Challenge

A major resistor manufacturer needed an alternative to ceramic for substrate material. The million-dollar question was, "could metal be held to the same or better flatness specifications?"

Solution

Absolutely. Careful process design and monitoring of the progressive die produces a 4" by 4" stamped metal plate with a flatness variance of less than 0.008".

This is not an expensive run, inspect, scrap, then run some more operation either. The process boasts consistent control and scrap rates less than 0.03% with hundreds of thousands of plates produced annually.

Isn't quality most cost effective when it is designed into the tools and die at the start of a project?

What improvements could precision metal stampings make in your world?
