Short for PWB, a printed wiring board features insulating substrates with conductive traces made by printing, etching and electroplating to realize electrical connection and signal control. Available in single-sided, double-sided and multi-layer structures, it delivers great insulation, uniform conductivity, compact size, high temperature resistance, corrosion resistance and EMI shielding. Custom wiring layouts, board materials and surface finishes are available to meet lightweight and high-density circuit design needs. It is commonly applied in industrial control, automotive electronics, smart home appliances, communication devices, new energy and precision instruments, serving as an essential foundational material for the modern electronics manufacturing industry.
