Significant improvements in yield and life span
Multitest’s Atlas contactor with the recently launched Atlas 040 probe has demonstrated substantial advantages over a competitive solution in an onsite evaluation at a major Asian customer. Both test yield and probe life span were significantly increased and contributed to a sustainable cost of test improvement for the entire test cell.
The Atlas contacting products are the next generation of Multitest’s revolutionary QuadTech flat probe technology. The Atlas 040 is a high performance contactor designed for 0.4 mm pitch WLCSP and large BGA ball count device-under-test contacting applications. The Atlas 040 was configured as part of a quad site setup with a LTX-Credence Diamond10 tester. The Atlas 040 contactor delivered a 25% longer life for the customer with 250K insertions and first pass yields were increased by 4 percentage points. With these results the Atlas contactor clearly met the customer’s criteria to increase yields, increase system uptime, and reduce costs. After this successful evaluation the Atlas was designated the customer’s contacting solution of choice.
Bert Brost, Product Managers, explains: “The development of the Atlas probe was driven by the customer’s need for a low cost probe that has the strength and reliability of a radial probe but at a fraction of the cost. The measurable focus was low cost, high bandwidth, long life, with low and repeatable contact resistance. Higher test yields and longer probe life directly translate into less test capacity required for retest, higher system uptimes and a significantly increase in the number of shipped devices.”
