Hermetic Solder Seal Lids
Typically used to seal ceramic packages, solder seal lids combine the lid and an accurately aligned solder preform as a single unit. This assembly makes it easy to position the lid on the package as the solder is already fixed in place. Solder seal lids offer distinct advantages compared to having lid and solder preforms as separate components.
Typically the lids are flat, but it is possible to use a stepped lid. Rapid prototyping is available in small volumes even when no standard tooling exists.
