Custom Capabilities: Mounting Options

For many types of passive components (e.g.through hole or surface mount) the mounting operation creates both an electrical and mechanical connection; however, with most wirebondable components the physical mounting only creates a mechanical connection and the electrical connection is made through wirebonds.

The exception to this is back contact resistors (BCR and IGBR) and thin film capacitors (NCx and CBx) where the backside of the component is also one terminal of the device. The method of attaching the die to the substrate influences whether and what kind of metal to have on the back of the die.
