Double-Sided PCB

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.

A printed circuit board (PCB) electrically connects electronic components by etching conductive pathways from a copper sheet laminated onto a non-conductive substrate. PCBs typically consist of a copper foil conducting layer and an insulating layer laminated with epoxy resin prepreg, with FR-4 being the most commonly used material. PCBs can be single-sided or double-sided, the latter allowing connections on both sides via through-hole plating. In electronics manufacturing, PCB prototyping is essential before mass production, enabling testing of the layout. While prototype boards may differ slightly from the final product, maintaining similarity ensures that the final PCB functions as intended. Read More

The diversification of PCB in materials, layers, and processes is suitable for different electronic products and their special needs, so its types are relatively diverse. Here are some generic ways to distinguish PCBs, and we can also introduce their classification and manufacturing processes at the Read More
