Experimentation cont. • FMU was used for various validations – Second Experiment – Insertion study to find optimal force vs. Pogo life •First run: –100,000 insertions were made at ideal force first experiment –LLCR measurements were taken periodically to see if resistance values increased •Second run: –100,000 insertions at different force –LLCR measurements were compared to first run Jan 10, 2002 Force Measurement on Sockets & Contactors 9
