Cantilever probe card with adjustable distance between carrying surface and seat
A recently granted patent (Publication Number: US11879912B2) discloses a cantilever probe card designed for testing electronic components. The innovative design features a carrier with a metal sheet that can be deformed through coarse adjustment members to reduce assembling tolerances between probe modules. These probe modules are placed on assembling regions of the metal sheet and include fine adjustment members to change distances between components, ensuring accurate testing results. The carrier also includes a retaining mechanism to limit the distance between the carrying surface and the seat within a predetermined range, enhancing the precision of the testing process.
Furthermore, the patent details the structure of the probe modules, highlighting the use of cantilever probes with soldering segments, testing segments, outer elastic arms, and focusing portions. These components are meticulously designed to create observation points for detecting apparatus during the testing process. The cantilever probes are configured to form enclosed spaces and have varying lengths of outer elastic arms to optimize their functionality. The carrier itself is equipped with coarse adjustment members to reduce assembling tolerances between different regions, ensuring the overall accuracy and reliability of the cantilever probe card for electronic component testing.
