Electroform Stencils are our specialty.
Stentech is a leading-edge company with the latest in stencil technology. With seven manufacturing facilities and over 130 dedicated and quality driven team members across North America, Stentech once again is ready to "raise the bar" in Quality, Delivery and Service.
Why Electroformed Stencils?
- The smooth trapezoidal sidewalls of an electroformed stencil allow for better paste release compared to polished laser or etched stencils. Electroform stencils provide fine and ultra-fine pitch apertures with paste transfer efficiencies at 95% and above, while minimizing bridging.
- Since the process occurs at an atomic scale, the aperture tolerances are in the micron range. Typically, +/- 10 microns (.0004") are achieved.
- Electroform foils are harder than full hard stainless steel of comparable thickness, providing for longer stencil life (hardness 500 Hv and greater). This durability is advantageous for high-volume runs.
- Nickel has a lower coefficient of friction compared to stainless steel, which allows for a better roll of the solder paste and decreases wear on squeegee blades.
- Allows for thinner stencils due to the increase in paste transfer efficiencies.
- Can mean an increase in production yields due to lower numbers of re-works.
- Stencils and foils can be produced in a non-standard thickness, if required, as well as step up, step down, and recessed areas (i.e. 2.4, 4.2, 5.7 etc)
- Large aperture counts can be completed faster and more efficiently with an electroform stencil due to the electroform process itself. This allows for a denser image area without any distortion due to heat transfer caused by laser cutting. (pad count: 1 to unlimited)

Although emulsion screens are one of the oldest forms of printing, they remain the most versatile to this day. Emulsion screens are made from a frame. Mesh is stretched onto this frame, and the mesh is then imaged ready for printing. ...
Inspection templates enhance the visual inspection process by guiding the operator's eye to a specific location on the board to check for the presence and correctness of components. Stentech uses state-of-the-art laser machinery to...
Pressfit fixtures are used to support products during the insertion or assembly process. During this operation, a considerable amount of force is required to insert the connector into the board. Stentech's design allows for c...
Stentech's Vacuum Plates provide support for the circuit board during the assembly process. Because we now manufacture highly complex and dense boards, this has become critical to avoid warping, sagging, and bending of the board. ...
