Problems solved by technology

[0002] In the original inspection of CCL incoming materials, the deformation of finished or semi-finished circuit boards under heat (mainly referring to the curvature of the substrate) used to be mainly visually inspected, but it was very inaccurate.
However, the measurement method used now is to put the caliper on the flat plate to see through the light, which requires an experienced master to judge, because the judgment is based on experience, the bending data is not accurate, and this method is difficult to quantitatively detect

Abstract

The invention relates to a curvature measuring instrument. The instrument comprises a frame, a slide caliper stand and a slide caliper, wherein the frame comprises two parallel guide rails; the slide caliper stand is connected with the guide rails in a sliding manner; the slide caliper stand is provided with an axial guide slot; the slide caliper is inserted in the guide slot and penetrates through the upper and lower surfaces of the slide caliper stand; the slide caliper and the slide caliper stand are locked by a bolt; and one end of the frame is provided with an inlet / outlet of the slide caliper stand. The instrument can accurately measure the curvature of a baseplate and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of a measuring instrument, in particular to a measuring instrument for measuring the curvature of a circuit substrate. Background technique [0002] In the original inspection of CCL incoming materials, the deformation of finished or semi-finished circuit boards under heat (mainly referring to the curvature of the substrate) used to be mainly visually inspected, but it was very inaccurate. However, the measurement method used now is to put the caliper on the flat plate to see through the light, which requires an experienced master to judge, because the judgment is based on experience, the bending data is not accurate, and this method is difficult to carry out quantitative detection. People long for more convenient and accurate detection equipment to be invented. Contents of the invention [0003] The object of the present invention is to provide a measuring instrument capable of accurately measuring the c...
