Reasons for blistering of multilayer circuit board

The environment in an industrial workshop is different from that of ordinary places, especially in production and processing workshops. Summer temperatures are already high, and combined with the heat dissipation from the machines, temperatures in the workshop often reach over 60°C, and in some cases even reach 80°C. The HDI PCB in industrial control equipment are the "brains" of the equipment. If they are not heat-resistant enough, problems can easily arise. These include circuit aging, component loss, and even direct short circuits. If the equipment stops, the entire production line will be affected.

At present, there are two general FPC welding processes, one is tin press welding, and the other is manual drag welding
