Abstract

Circuit cards containing electronic components are tested using a nodal impedance tester. In many instances misplacement of a component socket, such as a dual inline pin (DIP) connector socket, is the cause for rejecting a card. Misplacement of a DIP connector socket can be determined electrically using the same nodal impedance tester as used for checking circuit cards. Circuit cards have a gridwork of holes. Contact pins for electrically checking the location of a connector socket are added to the socket to meet the spacing of the gridwork of holes. This can be done by placing the two contact pins 10 between the existing rows of pins 11, as in Fig. 1, or the socket can be extended in length with the added contact pins 10 positioned in the extension, as in Fig. 2.

Electrically Locatable Connector Socket

Circuit cards containing electronic components are tested using a nodal impedance tester. In many instances misplacement of a component socket, such as a dual inline pin (DIP) connector socket, is the cause for rejecting a card. Misplacement of a DIP connector socket can be determined electrically using the same nodal impedance tester as used for checking circuit cards. Circuit cards have a gridwork of holes. Contact pins for electrically checking the location of a connector socket are added to the socket to meet the spacing of the gridwork of holes. This can be done by placing the two contact pins 10 between the existing rows of pins 11, as in Fig. 1, or the socket can be extended in length with the added contact pins 10 positioned in the extension, as in Fig. 2. The tester would then make a continuity check for the added pins at a predetermined location. If this continuity check fails, then the operator making the test knows that the connector has been misplaced or is missing. Misplacement of straight inline pin (SIP) connector sockets can be detected electrically by adding two electrically connected pins 20 (Fig. 3).
