Making in-process testing of glassed-pin packages possible before assembling connectors HyPac Probe High Frequency Coaxial Packaging Probe (40 GHz) D-COAX’s HyPac probe is a great solution for in-process testing of hybrid packages with glassed pin feed-thru(s). By probing the package feed-thru pins with fast rise time TDR or high frequency VNA via HyPac probe, manufacturers of the hybrid packaging can pretest package performance and interconnections before assembling actual connectors and therefore saving money by not assembling defective packages. The HyPac probe is a high frequency probe with low contact resistance and bandwidth of 40GHz. The probe has an impedance controlled airline that was designed to follow the contours of the spring pin shape inside the probe and the signal pin under test and thereby maintain the best possible performance. The use of spring-loaded probe tips makes the probe durable. The probe head has gold plated and rugged crown tips that make contact with the rounded pin of the glass bead. The HyPac probe shape was designed to be a conjugate to the DUT for mechanical compatibility and high frequency performance. The probe airline serves a double purpose: it controls the impedance for the glass-pin/probe-signal-pin transition and it also acts like a stop for the probe travel, preventing it to crash against DUT.

The glass bead installation in a hybrid package for a board to a flange 2.92mm connector application may use the HyPac probe to pre-test the glass bead installation and the connection to the board. Hybrid package with glass bead pin Hybrid Package with glass bead pins Uncorrected S-Parameters and TDR data of HyPac probe tested up to 54 GHz. In this data the DUT is a glass bead installation of a 2.92mm sparkplug connector. Using a higher test frequency than the 40GHz probe bandwidth allows the VNA to calculate a rise time at 54 GHz for the FFT transformation to a TDR response of 6.48ps. HyPac Probe...
