Abstract
A method for leak testing of a hermetic package closure comprises the steps of: creating a pocket in a lid; plating the lid; placing solder in the pocket; melting the solder in the pocket; drilling a hole through the solder and the plated lid creating an unplated area on the plated lid; testing the hermetic package closure for leaks through the hole; heating the solder reflow, wherein surface tension of the solder over the hole and the unplated area enable the solder to form a hermetic closure.
