About PCB Test Probes

　　PCB test probes are one of the necessary verification testing methods in the PCB industry. In the earliest industrial period, it was first implemented in developed countries in Europe and America, and it was not popularized and implemented in China until the early 1980s.

　　The earliest test probe specifications applied to PCB are P125, P100, P075, and P50. A small amount of needles such as: nine-claw head, crown head, three-sided cone head, cup head, etc.

　　With the development of industry and the continuous upgrading of electronic PCBs, electronic PCB test probes are also developing products of various specifications to meet the testing needs. From the earliest single-layer boards to the currently developed multi-layer boards and flexible boards, since different sizes of PCB boards require different specifications of PCB test probes to meet their testing, the probe specifications are also evolving. Such as: P160, P75, PL75, PM75, PL50, G1353, etc. Eight-claw crown head, self-cleaning three-claw crown head, Hb3 nine-claw needle with rubber tube, etc. are added to the needle. The materials for making probes are also becoming more and more diverse. A variety of probe sizes, head shapes, and elastic forces are available to meet testing needs.

　　The wide application of PCB test probes today has fully covered the entire PCB industry!
