SMT solder-paste stencils

Before parts are placed, solder paste is printed onto the pads through a stencil. Which type you want depends on whether you're prototyping or running production.

Framed Stencil

Foil tensioned in a permanent aluminum frame for production printing.

Frameless (Foil) Stencil

Bare foil used in a reusable tensioning jig or taped down by hand.

Prototype Stencil

A small laser-cut stencil sized to a single board.

Step Stencil

A variable-thickness stencil for mixed paste volumes on one board.
