Fine pitch probes are spring contact probes with pitches between 0.10 / 4mil and 1.00mm / 40mil.
In this pitch, direct soldering and the use of mounting receptacles is usually no longer possible. Therefore, almost all fine pitch probes are designed as double-sided spring-loaded contact probes. Fine pitch probes are installed in corresponding test sockets, which enable exact contacting of the test points. Feinmetall fine pitch probes are suitable for common components such as BGA, LGA, QFP, QFN or WLCSP. Precision and 100% quality control characterize these probes.In smaller pitches of 60 - 300µm, carrier needles (beams) are also used.
Line spacing 1.0mm each. Spring-loaded fine pitch probes with up to 0.2mm outer diameters and a length of only 3.0mm.
