Abstract

Abstract A high speed socket housing having a relatively simple manner of contact inspection and/or replacement is taught. Briefly stated, the device includes a chip carrier housing having a portion which is removable therefrom and which thereby exposes the contacts contained in slots or partitions in the housing. Thereby, upon removal of a portion of the housing an inspection, replacement, and/or testing of individual contacts may be accomplished without disturbing the remainder of the contacts or removal of the entire chip carrier housing from a printed circuit board.
