HF Probe adapter features SMA connector
Ironwood Electronics introduces HF Probe Adapter which allows high-speed testing of BGA, LGA and QFN devices while accessing the signals using testers via header pins. Features of the HF Probe Adaptor include shortest possible trace length for maximum speed, low inductance, low capacitance, blind and buried via PCB design technology.
The Probe Adapter consists of two parts: the Probe board with two rows of 2.54mm center header pins and 4 SMA connectors for differential signal pairs and HF Socket to accommodate the device under test. The spring pin contact socket is mechanically mounted onto the probe board.
To use, drop IC into the spring pin socket, and apply downward force using compression screw in the socket lid. PCB is designed with 100Ω controlled impedance. Connect transmitter and receiver to the SMA connector and the test system is ready. The spring pin socket is constructed with high performance spring pins.
The self inductance of the contactor is 0.98 nH, insertion loss < 1 dB at 31.7 GHz. Operating temperature of this probe board is -35 to 125°C.
