SMT Stencils Basics: What Are Laser-Cut Stencils? Differences from Chemically Etched Stencils and a Practical Selection Guide In SMT (Surface Mount Technology) production lines, the stencil is one of the most critical tools for achieving high-quality solder paste printing. High-performance SMT Stencils directly improve printing accuracy, reduce defects, and raise overall yield. The two main manufacturing methods today are laser-cut stencils and chemically etched stencils. This article explains what laser-cut stencils are, how they differ from etched stencils, and how to choose the right type for your application.
