QFN Probing Systems (Carrier Adapters)
These industry leading probing adapters for QFN/MLF allow probing connection to all pins of the chip. A high density male to male adapter provides interconnect from the probe board to the target attached SMT feet. The SMT foot is simply soldered to the same pads as for the IC using standard soldering methods. The IC is installed into the ZIF socket on the probe board. The probe board is connected to the PCB attached SMT foot with a male to male pin adapter. Stabilizers are tightened to target PCB to prevent movement when probes are attached. All pins are gold plated for highest reliability interconnect.
