AI Technical Summary
Technical Problem
The existing technology addresses the difficulty of positioning small-sized ceramic substrates during flying probe testing.
Method used
The positioning fixture, which includes a test stage, a supporting plate, a clamping assembly, and a negative pressure assembly, ensures that the ceramic substrate is firmly fixed in the test area through vacuum adsorption and cylinder-driven clamping, and uses elastic elements to provide clamping force to avoid impact damage.
Benefits of technology
It achieves efficient and precise positioning and inspection of small-sized ceramic substrates, ensuring that the inspection holes correspond one-to-one with the pads, avoiding substrate damage, and adapting to the inspection needs of different substrate models.
