Manual test fixtures with rigid needles or spring probes
Manual test adapters are often needed for functional and IC testing. There are two ways of contacting the test subject: either spring probes or rigid needles are installed in the adapter, depending on the application and the required pitch. A combination is also possible.
MicroContact installs rigid needle adapters, such as in Ingun kits, so that the product specifications can be met even at a pitch < 1.27mm. With an appropriate interface, adapters can also be installed on function testers from Marconi, Flextronic, and others.
