Problems solved by technology

[0010] However, no special testing equipment has been found for testing the properties of palladium alloy probes.
This situation is not only due to the new MEMS probe card technology and narrow field, it is difficult to have general-purpose equipment for direct application, but also it is difficult to manufacture special test equipment for testing the performance of palladium alloy probes. Due to the size of the MEMS probe card itself Tiny, the components are only millimeter level, so there are very strict requirements for the number of drive systems, if there are too many drive systems, not only cannot be arranged in a limited space, but also the problem of heat dissipation is difficult to solve

Description

technical field [0001] The invention discloses a MEMS palladium alloy probe testing device and its key structure and method, belonging to the field of IC manufacturing industry, and specifically relates to a device, method and related key technologies for performance testing of palladium alloy probes in MEMS probe cards. Background technique [0002] The probe card is a very important technology in the chip manufacturing process. Before the chip is packaged, the probes on the probe card directly contact the pads or bumps on the chip to lead out the chip signal, and then cooperate with peripheral testing instruments and Software control realizes automatic measurement, and then screens out defective products to ensure product yield. [0003] With the development of micro-electromechanical system (MEMS) technology, the size of the chip is getting smaller and smaller, reaching the order of millimeters, and the degree of integration inside the chip is getting higher and higher, r...
