Low-Volume PCB Assembly SMT Solder Paste Stencils Vendor

SMT stencils define:

Stencils, or SMT Stencils, are SMT-specific molds whose main function is to help the deposition of solder paste. The purpose is to transfer the exact amount of solder paste to the exact location on the empty PCB.

The classification of SMT stencils:

SMT stencil can be divided into: laser template, electro-polishing template, electroforming template, staircase template, bonding template, nickel-plated template, etching template.

Generally,laser stencil and etching stencil is most popular here

So you can provide us files to chose detail stencil size

Frameless SMT Stencils

CPF Stencils

Framed SMT Stencils

These solder paste stencils are designed for high volume screen printing on printed circuit boards.

Foils are permanently mounted into aluminum frames

Provide optimum solder paste volume control

Large variety of standard frames for every printer

Framed Multi-level / Step Stencils

These Multi-level Stencils offer superior flexibility in achieving the right solder paste volume deposit for components with diverse paste requirement.

Provide optimum solder paste volume control

Eliminate co-planarity problems

Foils are permanently mounted into aluminum frames

Framed UltraSlic Stencils

Framed Electroformed Stencils

Electroformed stencils offer the best paste release characteristics available and are frequently used for fine pitch (20 mil to 12 mil pitch) SMT applications on printed circuit boards. They are also used for µBGA's, Flip Chip, and Wafer Bumping (12 mil to 6 mil pitch).

The smooth trapezoidal sidewalls of an electroformed stencil allow for better paste release

Nickel has a lower coefficient of friction compared to stainless steel

Electroform foils are harder than full hard stainless steel of comparable thickness, providing for longer stencil life
