Electrical Engineering

Testing integrated circuits that employ an area array of I/O presents unique challenges because the face of the chip is not visible for probing. On chips that use perimeter bond pads the face of the chip is exposed, so signals on the wiring in the top layer metal may be probed while the chip is in operation.This is not possible when the face of the chip is hidden. This work proposes a way to probe test points on the top layer metal of chips that use area I/O. The method works by attaching the ch...
