Gremlins Lurking on Circuit Boards – What are these Gremlins on Circuit Boards? Corrosion. Microscopic corrosion can take out electrical boards in weeks. This is a silent killer like Corrosion that occurs Underneath Insulation (CUI). But unlike CUI where corrosion can take years to develop, this microscopic corrosion on circuit boards can attack quickly, within weeks, and can shut down equipment. The root cause typically is moisture, but sometimes chemicals in the air prove deadly to circuit boards. Further, the electronics industry created issues by moving to lead-free solder and miniaturization. This will be addressed as well.
