Stencil Technology for SMT production

Stencils are used by electronic manufacturers today to print solder paste, which forms deposits on a printed circuit board (PCB) to hold the electronic components in place. When reflowed, the components are then secured to the PCB.

In comparison, solder paste printing is similar to painting a wall in your home yet with one important difference. In order to precisely deposit solder paste, it must be applied to a specific position and its volume must be controlled.To accomplished this precision task, it is necessary to use a special steel plate called a stencil to control the printing of solder paste.

A stencil is a pre-made template that transfers solder paste to a bare PCB through a relative aperture layout. The stencil can be made of stainless steel foil, ploy film or other material. But stainless steel foil is the most popular stencil material because it can deliver high solder paste printing quality. Precise solder paste printing is the key step for accurate circuit board soldering; however, there are other important elements to consider to ensure quality solder paste printing:
