Advantages of Multi-metal Terminations for NonMagnetic, High Temperature Solder Applications

Contemporary electronic board designs are becoming more challenging to designers than ever before. In today’s thick film, component applications designers are often faced with a trade-off between process flexibility and component performance. In terms of magnetic sensitive applications, this often requires the use of components that are sensitive to processing or attachment methods and therefore limit options for installation. At times this restricts the use of certain solders, temperatures or multiple re-flow operations. In applications where extreme processing is used with vulnerable components, failure modes can include component detachment or intermittent loss of continuity due to metal leaching of contacts and terminals.
