Multitest announces that its installed base of WLCSP contactors is steadily growing. The contactors are running high-volume production at subcontractors in China, Taiwan, Singapore and other locations. They show outstanding lifetime performance, contributing to unreached cost of test.
Multitest has been shipping WLCSP contactors for the past two years, which is relatively short compared to the decades of past shipping contactors for singulated devices. During this time, the company has learned that its contactors last much longer in the wafer-level test environment than in the package-test environment.
While Multitest’s Mercury probes achieve a good life of 500-700k insertions in package-test environments, the company is seeing probes in wafer-level test environments that are lasting 1.5-4 M for insertions and continue to provide excellent performance. This helps to make Multitest’s WLCSP contactor the industry leader for total cost of test solutions.
Multitest (headquartered in Rosenheim, Germany) is one of the world’s leading manufacturers of test equipment for semiconductors. Multitest markets test handlers, contactors and ATE printed circuit boards. Globally, more than 700 employees serve the company’s customers in offices and branches in North America, Singapore, Malaysia, the Philippines, Taiwan, China and Thailand.
