St. Paul, MN. Multitest announced that its new 0.3-mm-pitch Atlas contactor successfully passed a demanding customer production-floor evaluation. The customer’s evaluation confirmed that the Atlas reduced the customer’s cost of test while improving test yield and increasing throughput. Based on the evaluation results, the customer ordered a significant number of Atlas 030 contactors to support its new-product WLCSP production ramp.
The key to the WLCSP Atlas’s high performance, high reliability, and superior electrical contacting is the combination of increased mechanical tip strength and short-probe electrical performance, Multitest said. Atlas WLCSP test contactors achieve mechanical
The cruciform tip provides increased tip rigidity with a much greater immunity to breakage than traditional WLCPS probes used in earlier-generation test sockets. The Atlas 030 has 0.310 mm of compliance for bump structures that requires a larger compliance window for reliable contacting in high parallel test applications.
The customer is a long time user of Multitest contactors, and after reviewing the new Atlas design it was eager to evaluate it, Multitest said, adding that the added strength of the Atlas cruciform tip captured the customer’s attention. The Atlas offers electrical performance that allows the customer to test to the true performance of the device.
Bert Brost, senior product manager, explained, “We are very proud of the positive result of the evaluation. The evaluation by the customer confirmed what we already knew—the Atlas 030 contactor is a high-performance solution for WLCSP testing.”
