2. Introduction
• Manufacturing chlorine is a laborious process with several steps that take time.
• The manufacture and assembly of chlorine should be carried out in a clean environment free of
contaminants.
• This is important to produce good quality panels that have been providing stable service.
• PCB manufacturing processes are briefly described in the following slides.

4. Designing Electronic Circuit
• With the increasing sophistication of electronic products, the demand for highly complex PCBs is increasing.
• PCBs are now designed intricately with lots of connections and interconnections.
• PCB design is one of the basic steps that must be carefully implemented.
• At the design stage, it is important that the manufacturer and the customer work in hand in hand.
• With technological advances, many PCB design programs have been developed, supporting
and facilitating the work of PCB Designers.

5. LayoutPrinting
• Once the customer approves the design, the design is printed on any
Photo gloss core transparent sheet
• Generally, laser printers are used to print the chart.
• Ensure that the layout is completely printed on paper. It is recommended
to sample print on plain paper, check for clarity of design
• It is recommended to keep printing unchanged.
• This helps in dry the ink completely.

6. Preparing Substrate
• Put some heat and pressure on the assembly, and keep it there for some time
• The layout of the PCB will now be attached to the paper and the copper plate
• The paper the chart was printed on should be removed at this point
• The easiest and fastest way to do this is to soak the substrate in water for some time.
• Wait a few minutes and take the substrate out of the water. Remove the sheet from the assembly.
• Paper waste in the pool. Remove leftovers by soaking the pool again in water for a few hours.

7. Etching & Drilling
• Excimer (UV)
• YAG laser (infrared)
• Carbon dioxide laser
• The purpose of drilling is to remove unnecessary copper traces from the substrate.
• Dip the group in the drilling solution for some time.
• You can rub the plate with a little bit of acetone once the drilling process is complete

The next step in the PCB manufacturing process is drilling holes. Small to large holes are created to
connect the PCB components using advanced laser engraving techniques, including:-
PCB Assembly Assembly Supplier in India contains only copper plate with PCB layout attached to it.

8. Electroless Copper Deposition
• The critical chemical step in manufacturing PCBs is the chemical
deposition of a very thin layer of copper on the walls of the holes.
• The thickness of the coating is usually kept as 1ml and sometimes it is
set as 0.5ml

9. Soldermask Applications
Coat the entire plate with a liquid welding mask. The plate is then exposed to high intensity UV rays
Soldermask is implemented to achieve the following:
• Protect copper circles from oxidation, damage and corrosion
• Prevent shortening of welding between components, and maintain circuit isolation during assembly

10. Assembling
Now, it's time to put all the electronic components on the holes involved in the plate.
The components assembled on the board include:
• Terminals and connectors
• Resistors
• Keys
• Capacitors
• Network components
• Diodes
• Transistors
• Integrated Circuits

11. PCB Testing
• The prefabricated panels are then dispatched for operation and
electrical tested to ensure optimum performance and quality.
• Various methods like Bed of Nails Test, Rigid Needle adapter, CT
survey test, the flight probe is used to test efficacy, operational
excellence and robust final assembly.
• Each PCB assembly is thoroughly tested against the original
panel data.

12. Cutting Individual PCBs from the Production Panel
• The final manufacturing stage cuts PCBs from the production
board.
• In general, PCB manufacturers use milling machines or
computer-controlled routers to reduce individual PCBs without
damaging other paintings in the painting.

13. Final Testing
• A EMS Company in India team of expertise inspectors performs a final inspection of the final assembly.
• Strict examination is done on individual panels to see any obvious defects such as scratches.
And also, across the team assembly is achieved with mechanical drawing.
• In addition, they also verify the board's compliance with the specifications provided by customers.
• In addition to manual scanning, many automatic scanning machines are also used at this stage for
final inspection holographic.

14. Conclusion
• As you can see on these slides, PCB manufacturing includes several time consuming steps that must
be taken very carefully.
• Any defect in these manufacturing processes will affect the performance, effectiveness and durability
of the final assembly.
• PCBs manufactured after the right manufacturing process will last for a long time, and provide
outstanding performance for many years.
