Cleaning mats
Cleaning mats (KRM) are used to clean contaminated test probe tips. A cleaning mat cut to the same size as the DUT is placed in the test fixture instead of the DUT. When the fixture is closed, the tips of the test probes are pressed into the cleaning mat. The specialised composition of the cleaning mats works to clean the test probe tips. Cleaning the tips is a simple measure that helps to prolong the life span of the test probes. However, even regular cleaning cannot prolong the life span of probes indefinitely. Daily cleaning of heavily contaminated test probes before starting tests is recommended. Test probes which are used less often, or which only have light contamination, can be cleaned once a week.
