Test pin


Test needles, also known as probes in the industry, are divided into spring needles (special needles) and general-purpose needles when used for PCB board testing. When spring needles are used, test molds need to be made according to the wiring of the tested PCB board, and in general, one mold can only test one PCB board. When using universal needles, only enough points are needed, so many manufacturers are now using universal needles; pogo pins are divided into PCB board probes, ICT probes and BGA probes according to the usage. PCB board probes are mainly used for PCB board testing, ICT probes are mainly used for on-line testing after plug-in, and BGA probes are mainly used for BGA package testing and chip testing.
