Brazing occurs at a temperature above 450℃. Braze Preforms are made of alloys customized into different shapes and dimensions specific to an application. The size of a preform is determined by the volume needed. Preforms are preferred for precision applications due of the uniform volume, consistency, and adhesion it delivers to the joint. Braze Preforms come in a variety of standard shapes e.g., rectangles, squares, discs or frames, and sizes as required by customers. COINING can customize preform geometry for any application. Dimensions can also be held to tight tolerances for volume accuracy.

How it’s made
COINING’s Solder Preforms are made of solder alloys and customized into shapes and dimensions specific to an application. Microstamped pieces of foil take the shape that matches solder joints, which optimizes soldering distribution in a precise manner. The size of a Solder Preform is determined by the volume of solder needed.
