    [Our Blogs] PCB Analysis
    Before the emergence of PCBs, circuits were composed of point-to-point wiring. The reliability of this method is very low because as the circuit ages, the rupture of the circuit can lead to an open circuit or short circuit at the circuit nodes. Wire winding technology is a significant advancement in
