Socket-assembly and the method of manufacturing

摘要

One-piece socket with aforementioned structure and manufacturing solves the problems of two-pieces socket. Such one-piece socket can be made thinner than two-pieces socket, making it possible to be used as CPU socket of products like notebooks, where exiting two-pieces socket couldn't be used. Also, as one-piece socket is more appealing in terms of price, it can also enter burn-in test market, where price is a determining factor.

主权项

1. A method of manufacturing a socket assembly between an integrated circuit (IC) chip and a main board, the method comprising steps for:
forming a plural pin holes in a socket; forming probe pins by cylindrically rolling both end portions of a flat board to contact each other; forming a upper latch at a upper portion of each pin holes in order to prevent the probe pins from pulling out of socket; forming a vertical protrusion on the bottom portion of a circumference surface of the pin holes; inserting the probe pins into the pin holes; and forming a lower latch applying heat and punching to vertical protruded bump or surrounding area of socket to form latch around lower part of pin hole, preventing probe pin from drifting down from the socket.
