Abstract

Depicted in the drawing is a ceramic cap, metallized along the bottom of its walls to permit joining by solder reflow to a matching seal band provided on the surface of a ceramic substrate (not shown). To prevent the occurrence of solder bridging at internal corners, a preferential flow path is created by extending the metallization upward into the cap interior at each corner.
