B) on the glass surface of absorption lamp box, in blank sheet of paper edge and the overlapping place in addition of flexible circuit board, cover aperture with blank sheet of paper, blank sheet of paper edge and flexible circuit board imbricate, and the flexible circuitry panel edges is pushed down at the blank sheet of paper edge;
C) open the air-breathing device that adsorbs lamp box, the flexible circuit board that is placed on the lamp box glass surface is attracted on the glass surface under the getter device suction condition;
Wherein, described lamp box comprises glass surface, and described glass surface has the dot matrix aperture, has getter device near glass surface one side in lamp box.
In the technique scheme, optimized technical scheme is that the little span of dot matrix is even, the matrix form arrangement.Optimized technical scheme is that getter device is electrodynamic type air pump or air bag.Optimized technical scheme is that glass surface is smooth and flat surface.Optimized technical scheme is that after flexible circuit board was placed on glass surface, the place beyond flexible circuit board covered upper glass surface aperture with blank sheet of paper.
Among the present invention, make the dot matrix of Small Holes, need to guarantee the smoothness and the flatness of the lattice plane of glass surface simultaneously at the lamp box glass surface; In glass one side of adding an air-breathing device is installed, lamp box glass surface flexible circuit board can be by adsorbed close on glass under suction condition, place beyond the lamp box flexible circuit board need be with (blank sheet of paper edge and flexible circuit board are overlapping in the blank sheet of paper covering simultaneously, stop up flexible circuit board aperture in addition, help to compress flexible circuit board simultaneously), can place flexible circuit board more smooth this moment, after flexible circuit board is adsorbed on the lamp box surface, handle with care on the workbench that scanner detects, flexible circuit board can be close to scanner glass surface, scanner can obtain the image of better effects if, improves the accuracy of measuring.
The invention solves when detecting flexible circuit board, its flexibility has caused flexible board can not be close to the glass surface of scanner, there are deviation in image and actual product that this irregularity degree has caused scanning, testing result just can not accurately reflect the problem of actual conditions, this patent has been invented a kind of absorption type lamp box, flexible circuit board entirely can be adsorbed on the lamp box surface, when lamp box is placed on the scanner, flexible circuit board also just has been close together with the glass of scanner, has obtained better technical effect.
