Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel mesh inspection technology, specifically a double-head thickness measuring device for steel mesh inspection. Background Technology
[0002] Stencil: A specialized tool used for SMT printing solder paste on PCBs. It consists of a 30-40mm thick aluminum alloy frame and a 0.05-0.15mm thick stainless steel mesh. The stainless steel mesh has many holes for solder application. However, due to the increasing miniaturization and precision of electronic components, the stainless steel mesh needs to be thinned for some of these holes, resulting in solder paste of varying thicknesses. Therefore, it's necessary to measure the thickness of the stainless steel mesh with a precision of less than 0.005mm.
[0003] Current measurement methods on the market: 1. Micrometer with digital display; one side is placed against the marble surface for measurement; the steel mesh is generally 736*736mm in size and 30-40mm thick; it is time-consuming, laborious, and laborious. If the micrometer with digital display is not zeroed, or if the stainless steel sheet is not fully attached, it is difficult to obtain an accurate thickness value.
[0004] 2. Another method is to take a 45-degree angled shot with the camera and use trigonometric functions to calculate the thickness; however, the camera is affected by the depth of field, and the deformation of the steel mesh is generally around 1mm, so it is theoretically difficult to achieve an accuracy of 0.005mm.
