A printed circuit board assembly forms an essential part of an integrated circuit. The main benefit of using a PCB to assemble a circuit is that you don’t need to wire each board-mounted component. PCBs have integrated conductive pathways, typically copper strips on the base, which conduct the current between the various resistors, capacitors, diodes and transistors.
For this reason, PCBs are particularly suitable for self-assembly kits, such as guitar effects pedals. If you are having trouble with the assembly process, how to troubleshoot your work?
you need a test meter so you can look at your layout and isolate each component you installed and test for its proper function as indicated
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
