How many bottleneck situations could be avoided if one could trust a design bureau that does the job in a professional manner and at a time frame, not expectable, from in house employees. Why, instruct a highly paid hardware engineer to lay out boards. Wouldn't it be more beneficial and more profitable to keep the ball rolling in R&D and let a specialized pcb design bureau do the work for you. Over 30 years of designing boards has given me the knowledge and expertise to do my part properly; the way expected in the Industry and by my customers. Custom layouts that reach from sky to underground; eg. from planes to mining applications with their respective regulations and specifications; such as, Mil-Specs, Aviation Standards, Intrinsically Safety Standards but also general ANSI / IPC Standard. My layouts reflect an extremely high & professional design standard; given the opportunity in being able to discuss any design issues with the hardware engineer throughout the design stage. To archive best possible layout and circuit performance interim design stages will be forwarded to the engineer; so optimum placement and tracking can be discussed; while still in design stage. Design Complexity: Have you ever seen an engineer starting the layout from scratch. The answer you may have heard - “I was assuming it all fits - but I just realized, it won't". I know just to good how much work, time could go down the drain in re-shuffling an entire layout. Assuming and guessing are 2 words in our vocabulary we can not tolerate in the industry we're in as both these words could become a very expensive exercise. An in house 'density calculation program' provides me with an instant, physical pcb density report; so, "any assuming or guessing" will be eliminated before I even place the first resistor. A netlist check will search through your provided netist for loose nets & duplicate designators, etc. Placement as well as routing is done interactively. All design rules, eg. creepage and clearances, tracking width and spacing, differential pairs, etc. will be added to the pcb file. In return I will have an error free layout and the design complies to your specifications.

With respect to physical board area available, component and pads density, an in-house formula will calculate the 3 most important figures: 1.) Packaging Density 2.) Estimated cost of design 3.) Estimated time to completion. Just to name some of the benefits when outsourcing: 01. no need to pay wages, overtime, superannuation, sick leave or, annual leave 02. no need to provide a workplace or, secure a workplace 03. eliminate bottleneck situation by taking some of the workload, of your engineers 04. no more disrupted layout sessions 05. faster design completion - thus, quicker to market (up to 40% faster than inhouse design) 06. professionally designed pcb's 07. instant density report, instant estimated design cost & completion time (a time saver of hours / days) 08. 'error free' netlist (a time saver of hours) 09. instant pin swapping within the pcb - without the need to access the schematic (a time saver of days / weeks) 10. adding new nets within the pcb - without the need to access the schematic (a time saver of hours / days) 11. 24 hour response to new designs & rework; workload not withstanding 12. peace of mind Time is Money; Time can also ruin a business!!! Amongst other delicate issues in today’s industry, “Time”, has become one of the most important factors; with such an immense and powerful impact in the world of business. Demanding customer, pressure on initial contract; it’s, manufacturability and delivery time; penalty rates for late delivery, etc... – a nightmare for any business! Contracting out pcb design will certainly free up 'Your Engineers time' to concentrate and proceed with higher priorities of the companies ongoing, world of R&D Contributing more hours towards, “a single design session” a day will not only result in a qualitative better layout and tracking, but even more importantly, gaining much faster design completion. The faster completion, the quicker to market.
Robi Artwork CAD Layout EDA PCB Design Bureau Robi Artwork 59 Jamaica Drive Phone @email QLD 4508 Deception Bay Australia int. +61 (0) 432 086 675 robi@robiartwork.com ADVB.DOC Designing PCB’s, for over 30 years will undoubtedly present the necessary experience, qualification, know-how and professionalism expected, in this industry. To whom this may concern! I’ve been designing boards on professional basis, since 1978. My experience has shown that R&D satisfaction has only come from major effort of the PCB designer in achieving the best possible layout. Therefore, communication with the R&D engineers is given first place throughout the whole design process so that optimum layout and tracking results, given the many issues which must be considered. These considerations encompass not only the fundamental PCB design rules, eg: high speed and /or impedance controlled signals, etc.; but also EMC requirements, assembly and test requirements, etc. Given the opportunity to prove my experience and efficiency, I shall provide and contribute to excellence in layout and design, manufacturability and time-to-market resulting, I am sure in complete customer satisfaction. I am highly motivated, adaptable and enthusiastic to join your R&D Design Team on a sub contract basis; where I believe that I can make a unique contribution to the success of your business. General Design Experience 3 years, (1972 – 1976) General PCB Manufacturing Experience 6 years, (1978 – 1984) Hand Taped Design Experience (1985 and ongoing) CAD Design using, Protel / Altium Design Suite Application Specific Experience Aircraft Application (Perkins Technology) Audio / Video Application (Fairlight ESP, Clarity EQ) Engine Control Application (Heinzmann S.E. Asia) High Current / High Voltage Application (Heinzmann S.E. Asia) High Current / Low Voltage Application (Fairlight ESP) Industrial Control Application (Foxboro Australia, QRail) Industrial PC Application (Stallion Technologies) Intrinsic Safety Application (NLT Australia) Mining Application (AIT, Leica Geo Systems) Networking Applications (Contemporary Control Systems, USA) Power Station Application (Foxboro Australia) Race Car Application (MSEtech, Perkins Technology) Sensor Application (Monitor Sensors, Environ Data) Traffic Control Application (Foxboro Australia, QRail) Summary Over 30 years of PCB Design Experience is quite something to look back to. Still, optimum placement & tracking, only results from a combination of both - A good team of experienced Hardware Design Engineer and experienced PCB Designer.

Dec ‘2005 FOXBORO AUSTRALIA P/L Position/Contract PCB Designer Protel98 / 99SE Design Spec’s New Design COPEPC (79.84%) 6 Layer Multilayer Board Single Sided Placement 6/6mil Design Technology 19.30/9.84mil Vias Design Constraints High Density Board 32 bit high speed data and address bus 33MHZ PCI Bus Crosstalk Issues on all the different Clock Signals to neighboring track Differential Pair Clock Distribution, Source and Load Termination Grounding, within the Ethernet Circuit. Well matched impedance and propagation delay of a feedback Clock signal to chip with the impedance and propagation delay of the true clock signal. Ethernet Chips may force me to go to 8 Layers Xilinx Pin-Pitch may force us to use micro-vias. PinSwapping on the 2 Xilinx BGA’s This was quite an interesting design. Board size, 233.35 x 160.02mm. By the time all the components were loaded and tracked it became quite a high density board; taken into account that I managed to stick to a 6 layers multilayer board. It most certainly didn’t look that way right at the beginning as 2, 160pin BGA’s and limited tracking space almost forced me to use 8 Layers. As I could have never justified 8 layers, I did my best to avoid it. Re-arranging the layout to create slightly more tracking space and a different approach of tracking made it possible. The next problem I had to deal with was 2, 100pin Xilinx BGA’s. Due to the actual pin pitch I could not place standard vias, nor could I track a signal from the inner rows to the outside. Just Impossible. The 2 options we knew of were to, either use “micro vias” or pay hefty penalty on smaller vias but drilled with 0.2mm. That’s what Printed Circuit Eastcoast, in Western Australia was telling me. Well – I didn’t like the idea, going for micro vias, but I also didn’t like Penalty Rates. I had to look for a decent and acceptable compromise. This wasn’t easy – but I found a way.

Pushing for more space; on board One of the bigger problems I had with this board was trying to archive a 100mil clearance on 200mil spaced pins. All the connectors facing the front also needed 2KV isolation. Getting these 8 Channels placed with 100mil clearance to each other was quite a bit tricky as I also had to consider all of the track work involved. April ’2002 PERKINS TECHNOLOGIES P/L Position/Contract PCB Designer Protel98 / 99SE Design Spec’s DV1PC (77.63%) 4 Layer Multilayer Board Double Sided Placement 6/6mil Design Technology 26/14mil Vias Design Constraints Fixed location and orientation for all the connectors, flash card holder and Ethernet. Height Restrictions, 1KV & 2KV Isolation This particular design was quite different and challenging. Restricted by board width, component density and governed by fixed locations of connectors & cardholder, I tried to place the main components with respect to the flow of tracking. This didn’t look good at all. The entire bus was back to front. A 100pin Xilinx and the 16bit buffer were the only chips onboard where the signals could be rearranged. Based on the board density and tracking space required we placed components on both the sides - “double-sided placement”. Placing the 16bit buffer, the SRAM and Flash onto the solder side made a big difference to the main tracking; also freed up component side space, required for tracking. Due to extreme tracking density, but also 5 different supplies I was also forced to use “split planes”.

The idea was to shrink the board size as much as possible. Well, I did; but the board had become a 6 layer board. I just couldn’t fit all the tracking; all of the address and data lines in addition to the inter-connection of 4 SRAM. Believe me, I wasn’t real impressed with myself; still – Out of curiosity I rang the engineer, saying – Wouldn’t it be nice if Mitsubishi would make these chips in “mirror image pin out”, as well! This would make my life a lot easier; right now.. The engineer was laughing and said that I could have them in reversed pin out – if that’ll help. I almost couldn’t believe the engineer. Anyway - Using a set of, “standard” and a set of “reversed pin-out chips” made the tracking so much simpler and the board to be; only of a 4 layer design; saving 2 layers!

With over 25 years of experience in contract manufacturing I can honestly say the pcb layouts by Robi have been nothing short of excellent in regards to through hole and surface mount assembly. Component positioning and orientation suit any form of soldering; reflow, wave, gluing and wave. Customer Feedback; Manufacturing Synergy; Sydney - Australia Tim Tasi (2002) We have manufactured numerous PCB’s over the last five years which have been designed by Robi. The files received are always of the highest quality with a commonsense approach to the ease of manufacturability for any OEM or Contract Electronics Manufacturer. All relevant details are noted for the Bare PCB manufacturer which removes all Grey Area’s, during the PCB manufacturing process and in turn speeding up the production of final product. Customer Feedback R&D Contemporary Control Systems (CCS); Chicago - USA Bennet Levine (2004) …..; Robi, you have an interesting background and I think you could handle our designs. I will send you our NDA – once we’ve received, I will send you our next pcb design. Fairlight ESP; Sydney - Australia Kim Ryrie (1987) …..; this is to confirm that Fairlight has been using Robi Bittler for nearly all of our PCB designs since1987. I don’t hesitate to recommend the quality of Mr Bittler’s design Leeds & Northrup (L&N); Brisbane - Australia Col Higgins (1984) .....; the quality of work is excellent, delivery reliable and prices competitive. I have no hesitation in recommending Robi Artwork to other potential customers Foxboro; Brisbane - Australia Chris Sloane (1984) …..; has contracted Robi Artwork to produce pcb artwork since 1984. His quality of work is excellent, delivery is quick and reliable and prices competitive. The results always reflect the highest standard of design accuracy. I have no hesitation in recommending Robi Artwork to other potential customers

The way Robi did it without any second modification is really appreciable. I have no hesitation in saying that Robi artwork has all that quality; which is required by a good PCB designer Leica Geo Systems; Brisbane - Australia Rodney Gullickson (1987) We have used the service of robi artwork for the last 12 years. We are impressed with the quality of design; fast turn around times and his habit of not making assumptions, which in electronics can cause many problems. All the work is professional and any changes requested are promptly completed. MetaChip; Sydney - Australia Norman Jackson (2001) Robi Artwork has been designing PCBs for us for over 5 years. All of his designs are of excellent quality and have proved to be very reliable to manufacture. Robi's competitive rates, his extensive knowledge of pcb design and pcb process makes his service extremely attractive as a design partner. NLT Australia; Brisbane - Australia TJ Botha (2005) Robi has been designing multiple pcbs for us; to be used in explosive hazardous areas that need certification by an accredited body to be intrinsically safe to be granted EC EX ia approval. Robi had to work under tight timeline while having non conventional requirements. The EX ia certification requires strict requirements and segregation rules in the attempt to prevent sparking between tracks and components. Robi added a special layer to show this segregation to make the assessment simple and accurate. Robi's work was excellent and he was always willing to work in close relation to us through many engineering changes while we had to learn the ropes ourselves. The resulting products are currently used successfully in the market. I highly recommend Robi to other companies that may be in need of PCB designs. Perkins Technologies; Brisbane - Australia Adrian Ball (1984) Robi has done the PCB artwork for all my designs since 1984. Quality of work has always been excellent, as has the working relationship. I highly recommend Robi to any potential customer. Smart Av; Sydney - Australia Chris Alfred (1987) …..; I strongly recommend Mr. Bittler’s work to other designers. Stallion Technologies; Brisbane - Australia Bob Waldie (1984) …..; the work involved dense multilayer boards. We found Robi Bittler to offer a flexible and accurate service. He has many years experience in the industry and his workmanship is of the highest professional standard.

How many bottleneck situations could be avoided if one could trust a design bureau that does the job in a professional manner and at a time frame, not expectable, from in house employees. Why, instruct a highly paid hardware engineer to lay out boards. Wouldn't it be more beneficial and more profitable to keep the ball rolling in R&D and let a specialized pcb design bureau do the work for you. Over 30 years of designing boards has given me the knowledge and expertise to do my part properly; the way expected in the Industry and by my customers. Custom layouts that reach from sky to underground; eg. from planes to mining applications with their respective regulations and specifications; such as, Mil-Specs, Aviation Standards, Intrinsically Safety Standards but also general ANSI / IPC Standard. My layouts reflect an extremely high & professional design standard; given the opportunity in being able to discuss any design issues with the hardware engineer throughout the design stage. To archive best possible layout and circuit performance interim design stages will be forwarded to the engineer; so optimum placement and tracking can be discussed; while still in design stage. Design Complexity: Have you ever seen an engineer starting the layout from scratch. The answer you may have heard - “I was assuming it all fits - but I just realized, it won't". I know just to good how much work, time could go down the drain in re-shuffling an entire layout. Assuming and guessing are 2 words in our vocabulary we can not tolerate in the industry we're in as both these words could become a very expensive exercise. An in house 'density calculation program' provides me with an instant, physical pcb density report; so, "any assuming or guessing" will be eliminated before I even place the first resistor. A netlist check will search through your provided netist for loose nets & duplicate designators, etc. Placement as well as routing is done interactively. All design rules, eg. creepage and clearances, tracking width and spacing, differential pairs, etc. will be added to the pcb file. In return I will have an error free layout and the design complies to your specifications.

With respect to physical board area available, component and pads density, an in-house formula will calculate the 3 most important figures: 1.) Packaging Density 2.) Estimated cost of design 3.) Estimated time to completion. Just to name some of the benefits when outsourcing: 01. no need to pay wages, overtime, superannuation, sick leave or, annual leave 02. no need to provide a workplace or, secure a workplace 03. eliminate bottleneck situation by taking some of the workload, of your engineers 04. no more disrupted layout sessions 05. faster design completion - thus, quicker to market (up to 40% faster than inhouse design) 06. professionally designed pcb's 07. instant density report, instant estimated design cost & completion time (a time saver of hours / days) 08. 'error free' netlist (a time saver of hours) 09. instant pin swapping within the pcb - without the need to access the schematic (a time saver of days / weeks) 10. adding new nets within the pcb - without the need to access the schematic (a time saver of hours / days) 11. 24 hour response to new designs & rework; workload not withstanding 12. peace of mind Time is Money; Time can also ruin a business!!! Amongst other delicate issues in today’s industry, “Time”, has become one of the most important factors; with such an immense and powerful impact in the world of business. Demanding customer, pressure on initial contract; it’s, manufacturability and delivery time; penalty rates for late delivery, etc... – a nightmare for any business! Contracting out pcb design will certainly free up 'Your Engineers time' to concentrate and proceed with higher priorities of the companies ongoing, world of R&D Contributing more hours towards, “a single design session” a day will not only result in a qualitative better layout and tracking, but even more importantly, gaining much faster design completion. The faster completion, the quicker to market.

To whom this may concern! I’ve been designing boards on professional basis, since 1978. My experience has shown that R&D satisfaction has only come from major effort of the PCB designer in achieving the best possible layout. Therefore, communication with the R&D engineers is given first place throughout the whole design process so that optimum layout and tracking results, given the many issues which must be considered. These considerations encompass not only the fundamental PCB design rules, eg: high speed and /or impedance controlled signals, etc.; but also EMC requirements, assembly and test requirements, etc. Given the opportunity to prove my experience and efficiency, I shall provide and contribute to excellence in layout and design, manufacturability and time-to-market resulting, I am sure in complete customer satisfaction. I am highly motivated, adaptable and enthusiastic to join your R&D Design Team on a sub contract basis; where I believe that I can make a unique contribution to the success of your business. General Design Experience 3 years, (1972 – 1976) General PCB Manufacturing Experience 6 years, (1978 – 1984) Hand Taped Design Experience (1985 and ongoing) CAD Design using, Protel / Altium Design Suite Application Specific Experience Aircraft Application (Perkins Technology) Audio / Video Application (Fairlight ESP, Clarity EQ) Engine Control Application (Heinzmann S.E.

Dec ‘2005 FOXBORO AUSTRALIA P/L Position/Contract PCB Designer Protel98 / 99SE Design Spec’s New Design COPEPC (79.84%) 6 Layer Multilayer Board Single Sided Placement 6/6mil Design Technology 19.30/9.84mil Vias Design Constraints High Density Board 32 bit high speed data and address bus 33MHZ PCI Bus Crosstalk Issues on all the different Clock Signals to neighboring track Differential Pair Clock Distribution, Source and Load Termination Grounding, within the Ethernet Circuit. Well matched impedance and propagation delay of a feedback Clock signal to chip with the impedance and propagation delay of the true clock signal. Ethernet Chips may force me to go to 8 Layers Xilinx Pin-Pitch may force us to use micro-vias. PinSwapping on the 2 Xilinx BGA’s This was quite an interesting design. Board size, 233.35 x 160.02mm. By the time all the components were loaded and tracked it became quite a high density board; taken into account that I managed to stick to a 6 layers multilayer board. It most certainly didn’t look that way right at the beginning as 2, 160pin BGA’s and limited tracking space almost forced me to use 8 Layers. As I could have never justified 8 layers, I did my best to avoid it. Re-arranging the layout to create slightly more tracking space and a different approach of tracking made it possible. The next problem I had to deal with was 2, 100pin Xilinx BGA’s. Due to the actual pin pitch I could not place standard vias, nor could I track a signal from the inner rows to the outside. Just Impossible. The 2 options we knew of were to, either use “micro vias” or pay hefty penalty on smaller vias but drilled with 0.2mm. That’s what Printed Circuit Eastcoast, in Western Australia was telling me. Well – I didn’t like the idea, going for micro vias, but I also didn’t like Penalty Rates. I had to look for a decent and acceptable compromise. This wasn’t easy – but I found a way.

Pushing for more space; on board One of the bigger problems I had with this board was trying to archive a 100mil clearance on 200mil spaced pins. All the connectors facing the front also needed 2KV isolation. Getting these 8 Channels placed with 100mil clearance to each other was quite a bit tricky as I also had to consider all of the track work involved. April ’2002 PERKINS TECHNOLOGIES P/L Position/Contract PCB Designer Protel98 / 99SE Design Spec’s DV1PC (77.63%) 4 Layer Multilayer Board Double Sided Placement 6/6mil Design Technology 26/14mil Vias Design Constraints Fixed location and orientation for all the connectors, flash card holder and Ethernet. Height Restrictions, 1KV & 2KV Isolation This particular design was quite different and challenging. Restricted by board width, component density and governed by fixed locations of connectors & cardholder, I tried to place the main components with respect to the flow of tracking. This didn’t look good at all. The entire bus was back to front. A 100pin Xilinx and the 16bit buffer were the only chips onboard where the signals could be rearranged. Based on the board density and tracking space required we placed components on both the sides - “double-sided placement”. Placing the 16bit buffer, the SRAM and Flash onto the solder side made a big difference to the main tracking; also freed up component side space, required for tracking. Due to extreme tracking density, but also 5 different supplies I was also forced to use “split planes”.

The idea was to shrink the board size as much as possible. Well, I did; but the board had become a 6 layer board. I just couldn’t fit all the tracking; all of the address and data lines in addition to the inter-connection of 4 SRAM. Believe me, I wasn’t real impressed with myself; still – Out of curiosity I rang the engineer, saying – Wouldn’t it be nice if Mitsubishi would make these chips in “mirror image pin out”, as well! This would make my life a lot easier; right now.. The engineer was laughing and said that I could have them in reversed pin out – if that’ll help. I almost couldn’t believe the engineer. Anyway - Using a set of, “standard” and a set of “reversed pin-out chips” made the tracking so much simpler and the board to be; only of a 4 layer design; saving 2 layers!

With over 25 years of experience in contract manufacturing I can honestly say the pcb layouts by Robi have been nothing short of excellent in regards to through hole and surface mount assembly. Component positioning and orientation suit any form of soldering; reflow, wave, gluing and wave. Customer Feedback; Manufacturing Synergy; Sydney - Australia Tim Tasi (2002) We have manufactured numerous PCB’s over the last five years which have been designed by Robi. The files received are always of the highest quality with a commonsense approach to the ease of manufacturability for any OEM or Contract Electronics Manufacturer. All relevant details are noted for the Bare PCB manufacturer which removes all Grey Area’s, during the PCB manufacturing process and in turn speeding up the production of final product. Customer Feedback R&D Contemporary Control Systems (CCS); Chicago - USA Bennet Levine (2004) …..; Robi, you have an interesting background and I think you could handle our designs. I will send you our NDA – once we’ve received, I will send you our next pcb design. Fairlight ESP; Sydney - Australia Kim Ryrie (1987) …..; this is to confirm that Fairlight has been using Robi Bittler for nearly all of our PCB designs since1987. I don’t hesitate to recommend the quality of Mr Bittler’s design Leeds & Northrup (L&N); Brisbane - Australia Col Higgins (1984) .....; the quality of work is excellent, delivery reliable and prices competitive. I have no hesitation in recommending Robi Artwork to other potential customers Foxboro; Brisbane - Australia Chris Sloane (1984) …..; has contracted Robi Artwork to produce pcb artwork since 1984.

The way Robi did it without any second modification is really appreciable. I have no hesitation in saying that Robi artwork has all that quality; which is required by a good PCB designer Leica Geo Systems; Brisbane - Australia Rodney Gullickson (1987) We have used the service of robi artwork for the last 12 years. We are impressed with the quality of design; fast turn around times and his habit of not making assumptions, which in electronics can cause many problems. All the work is professional and any changes requested are promptly completed. MetaChip; Sydney - Australia Norman Jackson (2001) Robi Artwork has been designing PCBs for us for over 5 years. All of his designs are of excellent quality and have proved to be very reliable to manufacture. Robi's competitive rates, his extensive knowledge of pcb design and pcb process makes his service extremely attractive as a design partner. NLT Australia; Brisbane - Australia TJ Botha (2005) Robi has been designing multiple pcbs for us; to be used in explosive hazardous areas that need certification by an accredited body to be intrinsically safe to be granted EC EX ia approval. Robi had to work under tight timeline while having non conventional requirements. The EX ia certification requires strict requirements and segregation rules in the attempt to prevent sparking between tracks and components. Robi added a special layer to show this segregation to make the assessment simple and accurate. Robi's work was excellent and he was always willing to work in close relation to us through many engineering changes while we had to learn the ropes ourselves. The resulting products are currently used successfully in the market. I highly recommend Robi to other companies that may be in need of PCB designs. Perkins Technologies; Brisbane - Australia Adrian Ball (1984) Robi has done the PCB artwork for all my designs since 1984. Quality of work has always been excellent, as has the working relationship. I highly recommend Robi to any potential customer. Smart Av; Sydney - Australia Chris Alfred (1987) …..; I strongly recommend Mr. Bittler’s work to other designers. Stallion Technologies; Brisbane - Australia Bob Waldie (1984) …..; the work involved dense multilayer boards. We found Robi Bittler to offer a flexible and accurate service. He has many years experience in the industry and his workmanship is of the highest professional standard.
