Array Solders offers solder preforms in shapes such as washers, squares, discs, rectangles, and frames. Solder preforms can also be customized to specifically meet a customers’ desires.  Sizes can range from 0.010” up to 2”, although they can come in larger or smaller sizes.  Along with the shape and size, the thickness is also very critical. Typical thicknesses range from 0.002” up to 0.030”, but other thicknesses are available, as well. The most commonly applied tolerance is +/- .002″. To reach out to our engineering staff, click here.
