PCB lights are advanced lighting systems that utilize printed circuit boards (PCBs) to support and connect light-emitting diodes (LEDs). These lighting solutions combine LED lighting technology with sophisticated PCB design for lighting to create efficient, reliable, and compact systems. LED PCBs are a specific type of PCB where LEDs are soldered to the board, equipped with heat sinks to manage the significant heat produced during operation. This ensures optimal thermal management in PCB lights and extends their lifespan.At SQPCB, we offer tailored solutions for LED PCB manufacturing, delivering rapid prototypes and volume production with exceptional thermal and electrical performance.
