Solder PReforms
Flux-Coated Preforms
Solder preforms are precise shapes of solder that are manufactured to tight tolerances to give repeatable, accurate solder amounts that are efficiently introduced into the manufacturing process. Adding the flux directly onto the solder allows for an exact, correct amount of flux to properly complete the soldering process.

- Delivers Flux Precisely Where it is Needed
- Eliminates the Separate Fluxing Step
Flux-Coated Preform Products
Flux coatings for preforms are available in no-clean and rosin-based chemistries with a variety of activity levels to suit your substrate metallizations. Indium Corporation offers multiple unique flux coating processes with the ability to control the amount of flux to tight tolerances. Flux coatings range from 1-3%. Coatings can be applied to most shapes and sizes of preforms and can also be offered on solder ribbon and on InFORMS®.
