Custom Solder & Braze Preforms

Hi-Rel's solder and braze preforms keep it all together!

Our solder preforms and braze preforms provide an exceptional solution for attaching electronic circuitry and packaging electronic devices.  They provide both good thermal and electrical conductivity as well as an interface for electronic connections. Alloy selection and shape geometry/dimension are critical decision points and Hi-Rel not only understands the intricate physical and chemical requirements for solder and braze preforms, it excels at helping customers select the best material.

Extensive tooling is available for all common shapes with low cost tooling options for more complex geometries. With special attention paid to managing extremely tight tolerances, we offer square, rectangular, spherical and disc shapes for our braze and solder preforms that are often required for the construction of electronic packages.   Our washer shaped preforms are used to attach hermetic feed-thrus for electronic components.

Typical tolerances are +/- 0.003” for both length and width (tighter tolerances are available) and 10% of thickness tolerances are typical.
