1. Application: Medical Electronics Functional Requirements: Structurally intact; low thermal expansion Competing Technology: Stamped flat base, welded wire for posts Overall Size: – Base 0.25 mm thick, 1.25 mm square – Posts 0.5 mm diameter x 1.2 mm tall Part Weight: 0.007 grams Material: MIM-Alloy 42, subsequent Ni & Au plating

2. - Small Part! - MIM to replace existing process: - Base stamped out of gold- plated sheet - Posts made from wire form welded to base - MIM seen as a cost savings with better consistency

3. Parts needs to be solderable to the circuit board; bumps molded in to allow flow of solder under part One of two posts intact No cracks Minimal flash Posts strong enough to not deflect when wire is welded to posts; center support section added

4. Why MIM? – More consistent position of posts – Connection of the posts to the base is more reliable in a one- piece MIM part than the welded wire to the stamped base. – MIM Alloy 42 consistent with expected material properties – Economics of MIM regarding CAPEX, part price significantly better than stamp & weld – MIM a more repeatable for high-volume technology for this application
