ABSTRACT:
Disclosed is apparatus to enhance thermal energy transfer from a heater to a DUT in IC handler systems. The pick-up head of an IC handler system is made of metal blocks in maximal thermal contact, and further includes an electrically resistive and thermally conductive layer. The electrically resistive layer provides ESD protection to the DUT. The preferred apparatus uses a collapsible billows suction cup to secure, pick-up, and align DUTs.
