Tekmos sells many micro controllers and Flash memories that are in PLCC packages. These mature packages are not being supported by modern handlers, and so we are fortunate to have acquired both a number of MCT handlers, and production kits for packages sizes ranging from 20-pin PLCC up to 84-pin PLCC packages.
While old, the handler is capable of both hot and cold operation, and can test parts at a 1800 uph rate. The handler has a clever mechanism that reverses the part orientation during test. Parts that are fed into the handler with pin 1 first, and leave the handler with pin 1 last. This allows a tube of continuity rejects to be easily retested.
We also use this handler in our programming operations. We pre-program about half of our micro controllers, and to do so, we use the combination of our production tester and the MCT handler.
The MCT handlers are just another capital investment Tekmos has made in order to continue to support mature products.
