Problems solved by technology
However, since the printed circuit board made by high-density interconnection technology is thin and flexible, if the traditional centroid calculation method is directly applied to the above-mentioned thin circuit board, the circuit board will be bent due to the force when it is close, misaligned and may even be damaged by cracking
[0004] In addition, when using the above-mentioned centroid calculation method, the four sides of the circuit board need to be roughly parallel to the wall structure. When the skew angle between the circuit board and the wall structure is too large, the wall will The structure may put excessive pressure on the corners or sides of the board, which also increases the chance of damage to the board

Description
technical field [0001] The invention relates to a centroid detection device, and in particular to a centroid detection device which can calculate the centroid position of an object in a non-contact manner. Background technique [0002] High-density interconnect technology (high density interconnect, HDI) is a novel technology for making printed circuit boards. Compared with the general printing method, the high-density interconnection technology uses the build-up method to replace the traditional mechanical drilling, and the high-level high-density interconnection technology circuit board even uses two or more Multilayer technology, combined with electroplating hole filling and laser opening to produce printed circuit boards with high contact density and high wiring density, so that the printed circuit boards made have light weight, high circuit density per unit area, and signal transmission. Strong effect and low interference from radio frequency or electromagnetic waves. ...
