Printed Circuit Board 


A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.

Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.

Module PCB

There are mainly two types of module PCB in our company: Internet of things (IoT)/ communication module PCB and vehicle-to-everything(V2X) module PCB.

As the most basic perception layer of the Internet, the IoT/communication module PCB has continued to grow rapidly. Both long-term evolution vehicle-to-everything (LTE-V2X) and new radio vehicle-to-everything (NR-V2X) are important parts of self-driving, the development of the corresponding module board market is increasingly prominent.

Thermal PCB

As the mounting density of SMT increases, the effective heat dissipation area of electronic equipment decreases. Especially when the PCB temperature is greater than 70 , the reliability of the PCB decreases by 5% for every 1  increase. There are three ways of heat transfer: heat conduction, convection and radiation, and all of which are included in the thermal PCB.

Heavy Copper PCB

A PCB with a finished copper layer greater than 2oz is defined as a heavy copper PCB. Heavy copper PCB can achieve efficient and reliable power distribution. As a special type of PCB, heavy copper PCB is suitable for high-current capacity products. The significant benefits of heavy copper PCB are that it reduces the chance of circuit failure and enhances the heat transfer from the layer to an external source.
