What Is Stepped Steel Mesh?
Due to the different requirements for the amount of solder paste when welding various components of different sizes on PCB boards, ordinary laser steel mesh can only control the amount of solder paste through the size of the opening.
In order to achieve higher requirements for soldering effect and quality, some users require two or more different solder paste thicknesses on the same SMT template to achieve precise control of solder paste amount, which leads to the emergence of stepped steel mesh. STEP-UP local thickening STEP-DOWN local thinning.
Steel Mesh Production Process:
Laser+etching technology, the first step is to etch the thinned thickness area out, and then carve holes on the laser machine.
Classification of Stepped Steel Mesh:
Local thinning, local thickening, and dual process steel mesh. (Note that the dual process steel mesh refers to the simultaneous application of red glue and solder paste on the same surface of the board. Therefore, the dual process requires the production of two steel meshes, one of which is a regular laser steel mesh and the other is specially etched into a stepped steel mesh. Therefore, if the dual process steel mesh is noted, it is necessary to clearly indicate how it is made.)
