ABSTRACT:
A ZIF connector is mounted on a tiny PCB that carries damping components and flying leads that are connected or soldered to locations of interest on a PCB. There may be one or many of such ZIF connector/connection accessories in any particular test set-up. A ZIF browser is connected to an active probe's tip by short flexible extended transmission lines that lead back to a small interconnect PCB having plated lands that are inserted into the ZIF connector. The ZIF connector is good for just a limited number of uses, but this is in agreement the a customer's usage model for an inexpensive ‘disposable’ part. Furthermore, the limited lifetime of the ZIF connector/connection accessory is apt to be mitigated in cases where several are in use at one time. The precision microwave connection of the ZIF browser to a potentially delicate and expensive probe tip need not be performed frequently for replacement of the ZIF browser, as the plating on the lands of the interconnect PCB is made thick enough to allow those lands to have a lifetime of 1,500 or more insertions, which is two to three times the amount research suggests is a typical customer expectation.
