Abstract
1,018,622. Welding by pressure. GENERAL ELECTRIC CO. Ltd., and P. A. BARNET. Feb. 15, 1963 [Feb. 16, 1962; Sept. 24, 1962], Nos. 6059/62 and 36306/62. Heading B3R. The leads of electronic components are welded to portions of the conductors of a printed-circuit pattern, the conductors being mounted on an insulating substrate beyond which the portions extend, by electrodes engaging opposite sides of the members to be welded. In a known method the lead 2 of an electronic component 1 to be connected to a printed-circuit pattern formed in a layer 4 of copper foil on an insulating layer 5 is engaged by an electrode 9 and through a hole 7 provided in the insulating layer 5 an electrode 9 is engaged with the copper foil. Current passed between the electrodes welds the lead to the foil. According to the invention the layer of copper foil projects beyond the insulating material and the component lead and foil are gripped between the electrodes. To dissipate heat generated one metal block is placed in contact with the component and other components on the board 6 and another metal block is contacted with the other side of the board. Fins may be provided on the upper block to bend the leads down into contact with the foil 4. A hood into which cold air is blown may be arranged over the component.
