Profitable SMT Stencils

The acquisition of stencil is not only the first step of the collection is one of the most important. The main function of the model is to facilitate solder paste deposition. The goal is an exact quantity of material to transmit the exact location on the printed circuit boards. But SMT Stencils are worth remembering that there are important variables other than those within the model, which can affect their performance. These variables include particle size printer and the viscosity of the solder paste, style, material, squeegee speed and pressure, the splinter group of the stencil from packing effect, the thickness and solder mask flatness and flatness of the components. Etching and laser cutting are subtractive processes, electroplating is an additive process.
