Not many customers know that we offer full PCB design and layout services here at Epec. Design and layout may not be a full-time employable position, so there are advantages of having your PCB fabricator complete the PCB design for you, not to mention the time needed to accomplish this task. So, rely on Epec to be an extension of your electrical engineering team.
PCB designs can be difficult to manufacture. Working in tandem with your circuit board supplier is beneficial to both you and your supplier. It can save cost, reduce manufacturing challenges and prototyping.
Knowing what is needed for quoting purpose and at the time of your order is key to a smooth process.
In this webinar, we review what is needed in terms of the Bill of Materials and schematic details to accurately quote and deliver the exact PCB design and layout that you require.

7. Drilling A differentiation between plated-through (pth) and non-plated-through holes (npth) in your data is very important! Please export a single drill-file for pth and npth drills, each (e.g. Excellon or Sieb&Meyer). This rule applies also for blind and buried vias 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 7
8. Silk Screen The marking print eases assembly and additionally allows to apply a revision number on the printed circuit board. Multi PCB offers white and black marking print. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 8
9. Solder Mask Plated-through-holes (pth) can, of course, be exempted completely from solderstop (e.g. test points, etc.). In General, you should cover pths with solderstop to avoid solder-bridges! 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 9

11. Heat Sink Heat Sink help transfer heat to an area where it can be better dissipated. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 11
12. Solder Mask Variation in colors help distinguish between part numbers and even revisions. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 12
13. V-Scoring V-Scoring is used to prepare printed circuit boards for mechanical separation. In this process, the PCBs get a pull linkage, done with precise cutters. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 13
14. Scoring Angels Scoring is only possible in straight lines, horizontal and vertical, from and to PCB outer edges We advise to score only PCBs down to a minimum thickness of 1mm, for stability reasons (thinner PCBs: notch milling) 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 14
16. V-Scoring Cut-Outs as well as Contours are normally milled. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 16
17. H.A.L. HAL (Hot Air Levelling) is the most tried surface finish. It is suitable for standard SMD but for finepitch applications, a chemical surface is preferable 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 17
18. Copper A very common surface with characteristics closely resembling those of HAL. Due to a faster oxidation process, shelf life depends strongly on temperature and packaging. Fingerprints on the surface should be avoided at all costs! 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 18
19. Silver A surface very similar to chemical tin, with better attributes at oxidation and for contact appliances. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 19
20. Gold Chemical gold, as well as chemical tin and silver, has a very planar surface and good oxidation resistance. It is suited splendidly for finepitch and bonding (alu wire) appliances. Chemical gold has replaced carbon print for keyboards. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 20
21. PC Slots PC / PCI slots are f.e. used to connect printed circuit boards directly to main boards (motherboards). It is differentiated between PC-AT standard with a grid space of 2.54mm and PCI standard with a grid space of 1.27mm between the gold fingers. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 21
22. Chamfering Chamfering of the gold fingers is to be avoided at all costs, therefore they need to have a spacing of min. 0.7mm from the PCB edge. We advise you to connect the gold-fingers with 200µm tracks to the edge (see sketch). Due to the production process, gold fingers are always connected with the edge like this. 10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A 22
