Medium and Full Production

Every mass production in the semiconductor industry goes through three levels of testing: Wafer-Level Testing, Package-Level Testing, and Module-Level Testing.

Rule of thumb across the semiconductor industry is to reduce testing time because time means money!  For example, for a one million devices lot testing, if the engineer is able to reduce its test time for one second per device, s/he will be saving one million seconds for testing this lot.  That’s about 278 hours saving on test equipment rental, utilities, and resources!

However, module testing, unlike wafer and package testing, comes in different shapes, sizes, and varieties.  It often requires more time and resources to set up and test. Custom test fixtures often need to be designed and built to support module testing and production turnarounds.  

RTI designs and manufactures custom test fixtures for 1mm square dies to large complex PCBs and everything in between. We design fixtures to test medical hybrids, hybrids used for space satellites, multi-chip silicon-on-silicon modules, optical devices, cell phones, RF sub-assemblies, fingerprint detectors, guitar amplifiers, and many other applications. Our test fixtures have been used for both engineering evaluation and production test.

Our design tools include both 3D mechanical modeling as well as schematic generation and PCB layout. Combined with our own in-house machine shop allows us to design and produce unique, high quality, and reliable custom test fixtures.

We have developed several 'semi-custom' test fixtures that can be adapted to different applications. See examples of our 750 Series Fixture, RF Module and Small PCB Fixture, and our Large PCB fixture requiring contact on both top and bottom of the board.
