6.9 – Improved BGA shock and bend performance using corner glue epoxies

Posted by Michael Kochanowski and Brian Toleno on 01 December 2006 at 10:57

The adoption of lead free solders has decreased the reliability of BGA packages subjected to shock and bend events. Also, as BGA packages grow in footprint and as pitches shrink, they are at increased risk of failure induced through handling. Capillary flow underfills can be used to significantly enhance the reliability performance of BGA packages. However, underfilling larger packages can take significant time. This can translate to slow assembly rates or multiple underfill machines operating in parallel to meet throughput requirements.
