Why OSP PCB probing challenges arise? It happens due to the sensitive nature of Organic Solderability Preservative coatings used on printed circuit boards. OSP surfaces can oxidize quickly and may not provide consistent electrical contact during repeated testing. Our specialized probe tips and materials are often required to maintain reliable contact without damaging the surface. Proper probe force and fixture alignment also play a vital role in successful probing. Understanding these challenges helps in selecting suitable probes and maintaining accurate measurements during ICT and functional testing processes in electronics manufacturing.
