The ability to accept all TSSOP 173 devices with from 14 to 28 leads is featured in the Model 3923 Multitest socket. The high-frequency-response RF socket offers a universal contact block for Multitest 9308B and 9320 handlers. Its contacts will last up to 500,000 plug-in/plug-out cycles, it's claimed. The socket's body is made of Torlon, a high-grade plastic, to withstand the elevated temperatures and high wear of automated testing. Other features include an integrated ground contact for grounding to the device-under-test's bottom ground paddle. Ground contact inductance is as low as 0.035 nH.
