Background

In the existing SMT stencil manufacturing and using process, an adhesive method is generally adopted. The method comprises the following steps: the SMT template steel sheet is generally made of metal sheets, particularly the steel sheet is placed on a screen frame provided with a tension screen gauze, the steel sheet is fixed on the screen gauze by using an adhesive, the screen gauze in the middle area is removed, the tension of the screen gauze is released onto the steel sheet, and therefore the steel sheet forms tension, but the steel sheet is further scrapped due to the fact that the tension of the steel sheet is reduced in the using process of the SMT template due to the problem of glue solidification.

However, the above scheme has the following disadvantages:

when tensioning operation is carried out through the hook seat, the hook and the stretching SMT template steel sheet clamp in the patent documents, the tensioning force cannot be adjusted according to the use requirements of SMT template steel sheets with different thicknesses, and the universality of the movable screen frame is poor.

To this end, we propose a movable mesh frame for tensioning the SMT platen steel sheet.
