Influence of electrically conductive adhesive amount on shear strength of glued joints

This paper deals with the influence of electrically conductive adhesive amount on shear strength of joints glued by EPO-TEK® H20S and MG 8331S. These joints were made by gluing of chip resistors 1206, 0805 and 0603 with two curing profiles for each adhesive. The different thickness of stencils and reductions of the hole in stencils were used. These differences have an effect on the amount of conductive adhesives on the samples. The curing profiles and various amounts of the adhesives have an effect on the mechanical strength of the joint. Samples were measured after curing process by using shear strength test with the device LabTest 3.030.
