SMT Stencil is a thin metal sheet used in the soldering process for SMT (Surface Mount Technology) and it plays an essential role in the SMT soldering process. Smt Stencil allows the direct placement of solder paste onto the SMD pads of PCB, which can help prevent errors and defects during the reflow soldering process.

The conventional paste stencil thickness including: 0.04mm, 0.05mm, 0.08mm, 0.1mm, 0.12mm, 0.13mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, 0.3mm and so on.

What material is used for SMT stencils?

The most common material is brass and stainless steel. In surface mount assembly, the stencil is the gateway to accurate and repeatable solder paste deposition.
