Assessment of Copper Bond Wire for Use in Long Term Military Applications
Assessment of Copper Bond Wire for Use in Long Term Military Applications
Aaron Lecomte -- Raytheon - Integrated Defense Systems
For years semiconductor manufacturers have used gold wire to connect the semiconductor die to the lead frames and external pins. However, rising gold prices are driving manufacturers towards less expensive alternative materials such as copper for use in high volume commercial plastic package devices. Military standards such as MIL-STD-883 do not define requirements for copper bond wire and therefore manufacturers are using qualification and process monitoring developed for gold wire to qualify the copper bond wire technology. Although copper bond wire designs are moving forward for commercial applications, there are concerns with quality and reliability for use of copper bond wire in high reliability military electronics with long mission life.
This presentation will review findings from the destructive physical analysis (DPA) testing performed on a number of standard commercial plastic encapsulated microcircuits (PEMs). We will focus on the die ball bond and lead frame crescent bond metallurgical structures, mechanical bond strength, wire composition, and manufacturing bonding process workmanship & overall quality.
Based on the DPA findings, potential risks will be defined along with recommendations to the qualification program of PEMs with copper bond wire for use in harsh environments and long term high reliability military programs.
