Dear all:
Merry christmas
I’m quality assurance engineer. Now I have some questions of die(LED) shear test by Dage4000.
Which point is the resonable test point? How to specify the shear height?
Best regards
Kyle

3um to 5um shear height from the pad surface is reasonable and common for most of the devices.
well, it is also depends on the devices. some devices are designate to have the shallow pad of probably 3-5um too,; therefore you shear height should be adjusted according to it.
