In order to ensure high quality PCB, PCB production needs reliability and adaptability test.

The temperature test of PCB circuit board is to prevent the PCB board from bursting, foaming, delamination and other undesirable reactions at excessive temperature, which leads to poor quality or direct scrap. It is a problem that needs to be paid attention to.

The temperature problem of PCB circuit board and its raw materials, solder paste, surface parts under temperature, usually the highest PCB circuit board high temperature 300 degrees 5-10 seconds; over lead-free wave soldering temperature is about 260, a lead is about 240 degree.
