Chip probing是什么意思
WebA probe card is essentially an interface or a board that is used to perform wafer test for a semiconductor wafer. It is used to connect to the integrated circuits located on a wafer to the ATE (Automated Test Equipment) in order to test their electrical parameters and performance before they are manufactured and shipped out. To make the process ... WebSep 6, 2024 · 第一道晶圆切割前的测试我们称为CP (Chip Probing), 因为这一道测试是在完整的晶圆上测的,用到的机台,我们称作Prober。 每一个产品,都会有针对自己设计的Prober Card, 上面根据芯片的测试焊盘(Pad)的位置装有对应的测试探针及电路与测试台连 …
