Whether engineers or PCB manufacturers, they inevitably encounter PCB failures. The occurrence of these failures may lead to delays in product delivery, damage to the manufacturer’s reputation, and increased time and monetary costs. (Most importantly, it costs money.) Today, we mainly discuss PCB failure modes and solutions. (It is recommended to save for later viewing, … Read more
Before the advent of PCBs, circuits were made through point-to-point wiring. This method had low reliability, as aging circuits could lead to wire breakage, resulting in open or short circuits at connection points. Wire winding technology was a significant advancement in circuit technology, enhancing the durability and replaceability of wires by winding small diameter wires … Read more
