Temperature Forcing Systems
Suitable for IC testing of all kinds of semiconductor chips, flash memory Flash/EMMC, PCB circuit boards, optical communications, electronic industries, etc.
It can isolate one IC or original component among many components and separately perform high and low temperature impact without affecting other surrounding device. Compared with the traditional thermal shock test box, the temperature impact rate is faster.
