I have been involved with electronic engineering, and systems repair for the last 35 years. I have designed everything from radios to computers, and everything in between. My methods are simple. Design the needed system, do the coding, prototyping, and testing. if all tests pass.then create the schematic, design the PC board and Gerber files, and have some samples manufactured. Then in the lab solder all components on the board, whether through hole or surface mount types. Test the circuit board, and deliver the product with all details.
