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.

Abstract
The utility model relates to a kind of ceramic substrate with flying probe tester positioning tooling.It includes: test table, support sheet, clamping assembly and negative pressure component;Support sheet is equipped with detection area, and several detection holes are equipped in detection area;The clamping assembly is composed of fixed clamping plate, movable clamping plate and first cylinder, and movable clamping groove is equipped on movable clamping plate, and fixed clamping groove is equipped on fixed clamping plate;The negative pressure component is composed of negative pressure cavity, movable cover plate and second cylinder, and negative pressure cavity with the detection area one-to-one correspondence, movable cover plate or the test table is equipped with the air extraction connector that is communicated with negative pressure cavity.The clamping assembly provides vacuum adsorption effect in clamping process, ensure that ceramic substrate is closely adhered on support sheet, so that it can guarantee that ceramic substrate is still kept horizontal when being clamped and fixed, ensure that detection hole in detection area and the pad on the bottom surface of ceramic substrate one-to-one correspondence.
