In this project lifespan, first pass yield and cleaning frequency were monitored. The Dura®Kelvin exceeded all targets significantly and the achieved life span of more than 4 mio insertions was more than four times the set target. First pass yield was improved from 95 -98.5 percent. The most amazing achievement is related to the cleaning frequency.
Dura®Kelvin only requires cleaning after approximately 100 hours. This reduces cleaning-related test cell downtime by 90 percent compared to the original test cell configuration. It also has a crucial impact, especially for cold test.
All of this leading-edge performance provides a unique cost of test advantage to the IDM.
