pin find its place against the test point as well as ensuring adequate and consistent contact force. At the same time, durability needs to be improved to minimise stoppages to replace broken pins and prevent false NG results that can result from poor electrical contact and inconsistent contact resistance.


A new type of test pin made with a specially developed electroformed (EFC) metal alloy and fabrication process now presents a solution to meet these demands. The custom material provides mechanical properties comparable to 304-grade stainless steel (SUS304/SS304) and meantime electrical properties achieving great conductivity at copper level. The combination of alloy properties and dedicated pin design (figure 3) allow one-piece pins that eliminate the size restrictions and potential for seizing associated with the conventional spring mechanism.

OPTIMISED ELECTRICAL PARAMETERS The pins let test engineers create high-reliability test fixtures with a pitch down to 0.175mm. Because the pins have been shown to make proper contact with the test point on over 99.8 per cent of test operations, the risk of false NG results from poor
