Marc Knox, IBM, “The Development of a Flexible and Efficient Chip Thermal Imaging Capability“:
Traditional burn-in systems hold multiple printed circuit boards (PCBs) with one or more devices in burn-in sockets to provide temporary electrical interconnect to a device under test (DUT). These PCBs and sockets are known as “burn-in boards”. And the systems in which they are loaded are “ovens” that permit temperature stressing, sometimes at both hot and cold temperatures, while stimuli are supplied to the chip. The purpose of “burning-in” a device is to screen for infant mortality in an accelerated manner.
The IBM team adapted a burn-in board system to Continue reading “IEEE Semiconductor Wafer Test Workshop – Probe Potpourri – Session Six (Tuesday)”
