ATE Test Probes -
1.27mm / 0.050" test centre The LPC1 Series is the universal size for use at 1.27mm test centres in the majority of ATE test fixtures. It has a very wide range of tip styles for almost all test targets. Additionally, a wide choice of spring forces is available. The ST-LPC1 series adds hardened steel tips which ensure an exceptional resistance to wear in high volume PCB production runs. The LF-LPC1 series has hardened tips, extra resilient plated surfaces and an enhanced pre-loaded spring pressure to enable good penetration of the tough residual contamination often found on the surface of many lead-free solders.
