ABSTRACT:
An improved anti-wicking connector for releasably connecting an integrated circuit or other electrical component to a printed circuit board. Electrically conductive contacts are pre-formed into a loop, horizontal section, and tail configuration for insertion into respective recesses of an electrically insulating housing. Housing recesses have top openings to receive integrated circuit leads and bottom openings to receive the contacts and through which the electrically conductive contacts extend for connecting to the printed circuit board. The loop of the contact is inserted into the housing recess and secured in place by heat-staking. Horizontal sections of the inserted contact loops are dimensioned to substantially seal the bottom opening of the recesses to prevent flux and solder wicking up into the housing which can tack or contaminate the I.C. leads during or after soldering of the contact tails to the circuit board. Integrated circuit leads are inserted into recess top openings until the distal ends of the I.C. leads abut the horizontal sections of the contact loops. Contact is also made between the end of the contact loop and the I.C. lead.
