Stencil Overview

Stencil Stencil is the process of depositing solder paste on pads

The PCB establishes the electrical connections.

It is achieved with a single material, a solder paste consisting of solder metal and flux.

The equipment and materials used at this stage are laser stencils, solder paste and solder paste printers.

To meet a good solder joint, the correct volume of solder paste needs to be printed, the components need to be placed in the correct pads, the solder paste needs to wet well on the board, and it must also be clean enough for SMT stencil printing.

Using laser stencil technology, you can create durable stencils on wood, plexiglass, polypropylene or pressed cardboard for dozens of sprays, depending on your needs.

To be able to solder SMD components on a circuit board, there must be an adequate solder library.

End faces on circuit boards, such as HAL, are usually not enough.

Therefore, solder paste is applied to the pads of the SMD components.

The paste is applied using a laser cut metal stencil. This is often referred to as an SMD template or template.

Keep SMD components from slipping off the board

During the welding process, they are held in place with adhesive.

The adhesive can also be applied using a laser-cut metal template.
