Foamed elastomers for packaging interconnections, testing and burn-in applications
Abstract
The present study is directed to a new foamed elastomer composition for supporting the interconnecting conductive wires in the ElasticonTM interposer connector for the packaging interconnections, test and burn-in applications. The compressibility of interposer connector can be tailored by introducing controlled volume fraction of foam into elastomer or filled elastomer. The foamed elastomer has been successful applied to a new Ball Grid Array (BGA) module testing socket to meet the contact force requirement.
