An epoxy filled via hole in a printed circuit board is presented. The epoxy filled via hole may have metal plating between the epoxy and the via hole walls of the printed circuit board. The epoxy filled via hole may have a land pad directly over the epoxy filling, creating a compact contact area for an ATE interposer.

In one embodiment, a mock wafer for calibrating automated test equipment includes a printed circuit board having a number of interconnect areas, with each interconnect area having a pair of mock die pads that are coupled via a connecting trace. In another embodiment, a method for calibrating automated test equipment (ATE) may include coupling the mock wafer to the ATE, and then causing the ATE to i) index the mock wafer with respect to a test head connector, ii) couple a number of probes or the test head connector to a number of the mock wafer's mock die pads, iii) transmit a test signal between a pair of the probes that are coupled via a pair of mock die pads and connecting trace of the mock wafer, and iv) calibrate a selected signal path or paths of the ATE by recording a characteristic of the transmitted test signal.
摘要:
In one embodiment, a mating circuit assembly is coupled and decoupled to a system by 1) mechanically and electrically coupling at least a first interposer, mounted on at least one of first and second substrates, to the mating circuit assembly. The mechanical and electrical coupling is accomplished using at least first and second spring mechanisms, with the first and second spring mechanisms being mounted between the connector housing and respective ones of the first and second substrates. At least one of the first and second substrates transmits signals between the first interposer and the system. The first interposer is electrically and mechanically decoupled from the mating circuit assembly by creating a vacuum between the connector housing and at least one of the first and second substrates. Other embodiments are also disclosed.
