Product Overview
Wide Range of Alloy Options
Available as a pure metal or metal alloy, solder preform are designed to reach liquidus at a certain temperature and provide specific mechanical and thermal properties. With over 250 standard alloys available, with melting temperatures as low as 47°C and as high as 1063°C. Check out our solder alloy selector guide to help you find the right alloy for your application.
Variety of Shapes & Sizes
Standard preform shapes include rectangles, squares, discs, frames, tubes and washers. Solder preforms can also be made into “special” shapes, customized to customers’ specifications. Typical sizes range from .010″ (.254mm) up to 2″ (50.8mm). Smaller and larger sizes, as well as custom shapes, are also available.
Preform Flux Coating
Indium Corporations proprietary flux coating process for solder preforms applies a uniform, consistent amount of flux to each solder preform providing a repeatable, low void solder joint every time. Flux coated preforms eliminate the need for manual fluxing, reducing process steps and offering a lower cost assembly process. Flux coating on the solder preforms can range from mild to strong, depending on the metallization’s being joined and the oxide levels on the metallization’s being joined.
Tolerances
Precision matters to ensure an accurate volume of solder. We offer both standard and high precision tolerances that will meet your design needs and assembly challenges.
