Problems solved by technology

In this way, because the jigs cannot be completely unified, the versatility between the jigs is not strong, and the design and manufacturing process of the jigs greatly increase the workload. Compared with the previous solution, this way more costly
[0008] Therefore, in the existing solutions, the fixed problems in the COF workpiece testing process are not well solved

Embodiment Construction

[0062] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present invention.

[0063] As described in the background, in the camera module industry, the requirements for pixels are getting higher and higher, and the requirements for testing accuracy of various workpieces are also getting higher and higher. Many existing test fixtures cannot meet the requirements for testing. Accuracy requirements, one of the root problems is the fixation of test artifacts during the test process. As mentioned in the background, although the existing...

Abstract

The invention provides a fixture preventing measurement deviation and a manufacturing method thereof. The fixture comprises a fixture body and a vacuum adsorption device. The fixture body is provided with at least one positioning groove suitable for accommodating at least one COF workpiece, and a bottom is formed; and the fixture body is further provided with a plurality of open holes disposed in the bottom where the grooves locate, and the open holes and the vacuum adsorption device form a vacuum adsorption structure so as to adsorb the COF workpiece.

Description

technical field [0001] The present invention relates to the design of a measurement fixture in the camera module industry, and further relates to the design of a measurement deviation prevention fixture. The design of the measurement deviation fixture applies vacuum adsorption technology to the design of the COF measurement fixture, so that COF is stable and fixed, which solves the industry's problem with the accuracy of COF testing. Background technique [0002] As the pixels of mobile phone camera modules are getting higher and higher, the requirements for the manufacturing accuracy of each component and the performance testing of the workpiece are also getting higher and higher. Almost every component must pass strict testing before it can be used in products. , so the accuracy and reliability of the testing process play a crucial role in checking the quality of the components. [0003] In order to obtain products with superior performance, the accuracy of the testing pr...
