EVALUATION OF WELDED CONNECTIONS FOR AIRBORNE ELECTRONIC EQUIPMENT

Abstract

Preliminary results of a NAVAIRDEVCEN investigation of welded connections and the results of investigations made by several manufacturers engaged in the production of welded assemblies and welding equipment are presented. At present an absolute nondestructive test for welded connections does not exist. Many materials are weldable, but all require determination and control of optimum energy and pressure to insure that a good metallic bond has been obtained. The most desirable lead diameters are in the range from 0.010 to 0.032 in. Minor cleaning of leads may be necessary but is not critical. The length of the component lead has no affect on the welded connection. There is some danger of component injury, but this can be practically eliminated. The over-all cost per unit of welded modules appears to be slightly higher than printed circuit boards. Other advantages of welded modules, which tend to offset their higher cost, include higher component density, expendable packaging, rapid construction, increased structural strength, and increased reliability.
