Design and etching PCB prototype by yourself The text provides a guide for making a printed circuit board (PCB) using a resist pen, ideal for quick, simple designs where appearance isn't critical. It emphasizes the importance of careful application to avoid removing the resist with the pen and suggests force drying the resist in a toaster oven. The process involves manually drawing component lead pads and traces, making it suitable for through-hole and limited lead-count surface mount components. The text also covers tips for drilling and marking the board, ensuring adequate resist coverage, and using a PCB layout program for more accurate results. Double-sided PCBs can be made by drilling holes first and using wire-wrap wires for vias. For professional results, the text suggests using SysPCB in Shenzhen, China, for FR4 PCB prototypes.
