DEK's Eform stencil manufacturing process has taken electroform stencils to the next level by incorporating an exclusive, sophisticated aperture height control method to their production of Eform stencils.

DEK's Eform stencils ensure seal contact to the pad(s), pad paste deposit and a greater percentage volume of paste on pad. The reactive force created by DEK Eform stencils provides for an even distribution of paste and allows for a more clean release of paste from the aperture. This technology also delivers ultimate control over stencil thickness and uniformity, ensuring outstanding paste volume consistency for fine pitch applications. As the electronics industry moves even closer to the reality of lead-free manufacturing, DEK Eform stencils will become a necessity, as they improve solder paste release for some of the more challenging lead-free solder paste formulations.

But, when DEK's Eform stencil process is combined with its innovative new technology, termed variable aperture height technology (VAHT), it becomes even more powerful. As Richard Tang, DEK global Eform manager, explains, "Board co-planarity issues are a prevalent problem. The uneven resist layer causes a poor seal between the board and the stencil, which can result in printing problems. DEK has that problem solved. The Variable Aperture Height Technology (VAHT), an inherent characteristic of DEK's Eform stencils, adjusts for the variances in resist layer heights and provides a uniform seal across the entire board". This powerful combination of technologies – Eform stencils with VAHT – results in superior paste printing.
