The PA4 Series is the universal size for use at 2.54mm 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-PA4 series adds hardened steel tips which ensure an exceptional resistance to wear in high volume PCB production runs. The LF-PA4 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.
