Our fine pitch spring probe (< 0.35mm pitch) adopts MEMS barrel design, make small pitch possible with higher force and stable contact resistance. The smallest outer diameter 20 microns with the wall thickness 5um. The MEMS barrel has features of uniform gold plating inside, spotless surface smoothness and highly precise cylindricalness, so the tighter sliding gap control possible to make more consistent contact resistance of probe during test condition.

Characters:
Thinner wall thickness for more internal space of higher spring force
Harder mechanical performance for fine pitch probe
Uniform gold plating inside
Spotless surface
Previse cylindricalness
