Packaged Part Holder (PPH)
SemiProbe manufactures a family of packaged part holders (PPH), which are fixtures that allow you to hold a variety of devices such as packaged parts, substrates, printed circuit boards. PPH can even hold a chuck that allows you to test wafers, partial wafers and individual die.
It is not uncommon for users to require both wafer and packaged part testing on the same probe system. There are a number of ways to integrate a PPH into a probe system. The PPH has a single lead-screw that allows you to open and close the jaws. The jaws have a grooved rail in them for easy insertion and clamping of the device under test (DUT). Most PPH’s are designed to hold devices ranging in size from 1” (25 mm) to 6” (150 mm).

SemiProbe manufactures a few different types of probe card holders. Most applications use rectangular shaped cards that vary in width from 4.5 “ (114 mm) to 6” (150 mm). The overall length of the card can vary. The electrical cable connections to the card can be with individual cables or a ribbon cable and they can be mounted at the back of or on top of the card. The probe card holder provides both coarse and fine theta adjustments. When in place the card can be levelled and locked.
