Preforms are usually made by stamping solder ribbon/strip that has been rolled to the specific thickness of our customer's application. Array Solders' Tooling and Wire EDM operation allows just about any shape to be fabricated and stamped in house.
Our preforms are made using dies that are designed to meet our customer's specifications. For obvious reasons, the price will depend on the complexity of the preform on the difficulty of making the tooling needed. For a special shaped preform, our Tool & Die department requires a drawing of the part for review before any quote may be extended.
The most commonly used performs are washers, rectangles, squares and discs with changes to their configurations.
Preforms are available plain, flux coated or flux filled.
