The heat resistance of the Robot 3step HDI PCB is an important item in the reliability of HDI. The thickness of the Robot 3step HDI Circuit Board becomes thinner and thinner, and the requirements for its heat resistance are getting higher and higher. The advancement of the lead-free process has also increased the requirements for the heat resistance of HDI boards. Since the HDI board is different from the ordinary multilayer through-hole PCB board in terms of layer structure, the heat resistance of the HDI board is the same as that of ordinary multilayer through-hole PCB board is different.
