Method for forming fine pitch contacts and fine pitch contacts obtained thereby

摘要

A method for forming fine pitch contacts (1) used in a ZIF socket comprises the following steps: stamping a contact strip (3) to form a plurality of contacts each comprising a first portion, a retaining portion (10) and a second portion being coplanar with each other, the first portion comprising a pair of arcuate arms (121) defining a circular receiving space (20) therebetween and a pair of parallel contacting fingers (120) defining engaging space (21) therebetween; bending the first portion to form a contacting portion (12) perpendicular to the retaining portion and the second portion; bending the second portion to form a soldering portion (11) perpendicular to the retaining portion and parallel to the contacting portion.
