The contactors have been deployed to multiple testing subcontractors in Taiwan and Singapore. The subcontractors report that the Mercury contactors provide a four to six percent yield improvement over the previous contacting solution, resulting in a significant cost-of-test savings. Additionally, the subcontractors are pleased with the Mercury contactors’ long life, low maintenance requirements and low replacement probe price.
Another fab-less manufacturer in Great Britain has purchased several 32-site Mercury wafer-scale contactors and sent one to a testing subcontractor in Taiwan where it is being used with great success.
The Mercury success story includes thousands of contactors for singulated devices, strip test and wafer-scale test. Mercury is popular because of its superior mechanical and electrical performance that results from its unique architecture and manufacturing process.
To quantify the performance, the probes have a bandwidth of approximately 20 GHz, a current carrying capacity of over 2 , an inductance of approximately 1 nH and a life of 500-800k insertions (values are pitch-dependent).
