Solder Preform (Sn63/Pb37, 15-Kilogram Reel, 0.020 x 0.040 x 0.019 inch)
Solder preforms are used in a variety of applications that require precise amounts of solder.
Preforms come in standard shapes such as squares, rectangles, washers, and discs. Typical sizes range from .010” (.254mm) up to 2” (50.8mm). Smaller and larger sizes, as well as custom shapes, are also available. Dimensions can be held to tight tolerances to assure volume accuracy.
Solder Preforms Packaging & Storage
Solder Preforms come in a variety of packaging options, including tape and reel. To minimize excessive handling, and exposure to air and subsequent oxidation, Solder Preforms should be packaged according to the quantity used during a typical work shift.
Store in the original container, closed securely, at 55% RH or less and at temperatures less than 22°C. Solder Preforms can also be stored in an inert atmosphere, such as a nitrogen dry box.
Solder Preforms Shelf Life
The shelf life of Solder Preforms is dependent on the alloy composition. Pb-free alloys, and alloys with a lead content of less than 70%, have a shelf life of 1 year from the date of manufacture (DOM). Alloys with lead content >70% have a shelf life of 6 months from the DOM.
