FPC supplier tells you a PCB stencil is a small piece of material with holes that affect the layout of parts on a board. Solder stencils are the most common PCB stencils that you can use to apply the right amount of solder paste accurately in a single round across the PCB. Your PCB becomes ready to fix Surface Mount Devices (SMDs) after using solder paste on its surface enclosed with a stencil. After removing the stencil, the solder paste deposits remain on the surface with formations of the stencil’s apertures.

FPC supplier tells you the smooth deposition of the paste creates accurate solder joints, ensuring high mechanical strength and excellent electrical connections.

There are two main types of stencils: framed and frameless stencils. Frameless stencils are cost-effective and easier to store, but they are not ideal for high-volume PCB printing. The stencil material significantly affects its ability to apply solder paste via the holes. Nevertheless, you can increase your stencil’s paste discharge capability by coating it.
