Quencher clamping operation using an electromagnet

摘要

A method of embedding a magnetically attractable member (25) in a ceramic material (1) and a system therefor wherein there are provided a magnetically attractable member and a ceramic member capable of being placed in a molten state. The magnetically attractable member is disposed over the ceramic member and the ceramic member is placed in a molten state. The magnetically attractable member is then disposed in the molten ceramic member by magnetic attraction and the molten ceramic member is then hardened around the magnetically attractable member. The magnetically attractable member is taken from the class consisting of Alloy 42 and Kovar. The ceramic member is preferably a glass. The ceramic member is preferably disposed on a semiconductor package and the magnetically attractable member is preferably at least a portion of a semiconductor lead frame.
