Standards for PCB Thermal Shock and T Testing

Standards for PCB Thermal Shock and Temperature Testing Electronic components generate heat while they operate, which will heat up the rest of your board. Heat will move to cooler areas of the board, but a board that reaches high temperature without quickly dissipating heat is prone to failure. Thermal shock testing aims to evaluate a design to ensure it can withstand thermal shock and comply with important application requirements. The best set of design tools, like the circuit board layout features 阅读文章
