PCB Manufacturing Process

Printed circuit boards (PCBs) form the backbone of all major electronics. These miraculous inventions pop up in nearly all computational electronics, including simpler devices like digital clocks. For the uninitiated, a PCB routes electrical signals through your electronics, which satisfies the device's electrical and mechanical circuit requirements. In short, PCBs tell the electricity where to go, bringing your electronics to life.

In here we handle the PCB manufacturing process for you from start to finish, but we believe it's important that our clients understand what we do - this ensures that your design specifications better serve your interests. Proper understanding of the PCB manufacturing steps prevents unnecessary errors from getting transmitted during the design stage. It also helps designers stay abreast of the latest printed circuit board manufacturing methods.

How Is a PCB Manufactured?

1.Hole drilling for holes, leads and vias on the bare dielectric substrate (e.g. FR4) followed by cleaning.

2.Activation for electroplating (applying a thin conductive layer) and rinsing.

3.Copper electroplating and rinsing.

4.Surface polising and cleaning.

5.Photoresist application, UV exposure and photoresist development (removal of either exposed or unexposed resist, depending on chemicals used).

6.Copper etching, rinsing and photoresist removal.

7.Solder mask application, UV exposure, development (removal of either exposed or unexposed solder mask, depending on chemicals used) and curing.

8.Optional tin and/or gold plating of exposed copper followed by cleaning.

9.Silkscreen printing, ink curing.
