The standard minimum trace width and spacing for industrial HDI PCB per official IPC 2226 standard is 25μm for inner layers and 30μm for outer layers for stable mass production, while ultra-fine prototype HDI designs adopt 20μm trace spacing matched with professional laser microvia fabrication for consumer electronics and automotive Read more
A heavy copper PCB is a printed circuit board built with thicker copper than a standard board, designed to carry higher current, improve heat dissipation, and deliver better durability in demanding applications. It is widely used in power electronics, automotive systems, industrial equipment, renewable energy, and high-reliability products. If you Read more
A PCB antenna is a small antenna made by etching copper foil or other conductive material into specific patterns on a printed circuit board (PCB). Its job is to send and receive wireless signals. Unlike external antennas that need to be added separately, a PCB antenna is built directly into Read more
If you’re designing, sourcing, or manufacturing PCBs, PCB OSP finish is a critical choice that impacts performance, cost, and reliability across every electronic assembly step—and getting it right means avoiding costly reworks and failed production runs. PCB OSP finish has become a go-to for high-volume and high-precision electronics, but navigating Read more
MCPCB provide superior heat dissipation for electronic products by integrating a highly thermally conductive metal core layer (typically aluminum or copper) into the circuit board. With the miniaturization of modern electronic devices and the ever-increasing power demands, the heat dissipation capacity of traditional PCB often fails to meet the needs Read more
