Pickering Interfaces model 65-22x Modular LXI Matrix Reed Relay Modules

Pickering Interfaces’ Modular LXI Matrix Reed Relay Modules (model 65-22x) were originally designed to test semiconductors at wafer and package levels. The reed relay matrix solution combines Pickering’s LXI Modular Chassis (model 65-200) with its plug-in matrix module range, providing access to all signal connections on 200-pin connectors. The plug-in modules are constructed using Pickering Electronics’ reed relays, which offer high performance as well as fast operating times.

The range includes four plug-in models covering matrices of up to 1536 x 4 in increments of 128 (model 65-221), 768 x 8 in increments of 64 (model 65-223), 384 x 16 in increments of 32 (model 65-225) and 192 x 32 in increments of 32 (model 65-227). Users can specify as many or as few plug-in modules (up to six) required and can field upgrade the chassis to extend the matrix when necessary. Over 1500 relays can be closed simultaneously for specific conditions for parametric testing.

The plug-in matrices offer built-in scan list sequence stores with triggering capability, providing users with the ability to set a series of predetermined sequences on an LXI instrument. The sequences can be triggered by software or one of the 16 DIO software-configurable open collector triggers. They also feature multibus capability for parallel testing.

The range includes Pickering’s Built-in Relay Self-Test (BIRST) and is supported by the company’s eBIRST Switching System Test Tools. These tools provide a quick and simple way of finding relay failures within the modules. Besides semiconductor testing, applications can be found in several other industries, such as the functional verification of automotive ECUs.
