Abstract
The invention discloses a reinforcing apparatus for improving mesh stretching tension. The reinforcing apparatus comprises a screen frame and two sets of reinforcing devices, wherein the screen frame is a hollow frame structure composed of two groups of opposite sides and has through holes penetrating the inner and outer sides of the opposite sides, each set of the reinforcing devices comprises a screw mechanism, a cushion block and a gasket, the screw mechanism comprises a threaded screw and a threaded nut, one end of the screw is fixed through the through hole in one of the opposite sides, and the other end of the screw is connected with the nut through the through hole in the other opposite sides. The nuts are span to compact the opposite sides so as to allow the screen frame to have inward deformation, so after the reinforcing apparatus is dismounted, secondary mesh stretching of a silk screen is realized, and the problem of poor solder paste removal capability due to unsmooth rebounding of a template caused by insufficient silk screen tension is overcome. The invention further provides a corresponding application method.
