Long before printed circuit boards (PCBs) appeared in films. There were already vacuum tubes performing a similar function. At the simplest terms, PCBs are utilized for linking components in electronic goods in a hassle-free and more economical manner. Typically, PCBs are made of insulating material. Pcb’s are coated with metal, either on the bottom of…

Introduction to aluminum pcb board Aluminum circuit board is the most common circuit board among metal PCBs. The aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Generally, a single panel is composed of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal base layer. Because…

Nowadays, the demand for electronic PCBA hardware terminal customers for electronic contract manufacturing services is increasingly strong. The traditional PCBA manufacturers, due to weak supply capacity, lack of price advantage, unstable supply, and low labor efficiency, lead to low conversion rate and face the problems of fewer and fewer customers. However, in the process of…
