Episode description
Even though we talk a lot about PCB assembly on this show, one aspect of the process still remains a bit of a mystery to Chris and Melissa - the ins and out of the PCB fabrication process. On this episode are joined by Dave Wilcox, a CAM engineer at CircuitHub who has been working with PCBs for 32 years. Dave gives us a 10,000 ft level overview of the PCB fab process, using a simple, standard 1.6mm thick, 2-layer board as an example. He breaks it down into all the steps that have to take place in order to have a finished circuit board that is ready to be assembled:
- Engineering/CAM
- Drilling
- Print Outer layers
- Plating and Etching
- Solder Mask
- Surface finish - ENIG/HASL
- Silkscreen
- Routing
