Abstract

The device consists of a plug which is inserted between adjacent circuitry cards to interconnect or jumper between them. The circuitry cards or the plugs can be heated to reflow solder between the plug and the cards. Circuitry cards, for example, core storage memory planes 10, 12, 14, and 16 are provided with connection lands 18, 20, 22, and 24 which can be of the printed circuit or molded-in type. Plugs 26 and 28 have electrically conductive portions 30 and 32 which extend into lapping contact with the lands 18 and 20 and 22 and 24 respectively, when the plugs are inserted between the cards as indicated.

Heated Plug for Array Jumpering

The device consists of a plug which is inserted between adjacent circuitry cards to interconnect or jumper between them. The circuitry cards or the plugs can be heated to reflow solder between the plug and the cards. Circuitry cards, for example, core storage memory planes 10, 12, 14, and 16 are provided with connection lands 18, 20, 22, and 24 which can be of the printed circuit or molded-in type. Plugs 26 and 28 have electrically conductive portions 30 and 32 which extend into lapping contact with the lands 18 and 20 and 22 and 24 respectively, when the plugs are inserted between the cards as indicated. Each plug is provided with a built-in electrical heater 34 and 36 which are utilized to heat the plug so as to reflow solder to make a connection between the conductive jumper areas 30 and 32 and the lands with which they make lapping contact. The plugs can be either made of material which has good thermal conductivity or the heater can be located close to the plug conductors. Alternatively, the plugs can be so shaped that heated gas flows over separate plug conductors without intermediate which has good thermal conductivity or the heater can be located close to the plug conductors.
