Electroform Stencil

FCTA Mexico manufactures electroformed nickel stencils to offer superior paste release as industry standard board designs demand smaller apertures and pitch. Electroformed stencil aperture walls are smooth (mirror-like), providing less surface area for solder paste to cling to. Instead of laser cutting apertures, nickel is formed around a photo resist template of apertures that matches board designs.  Electroforming also allows quick turnaround times for jobs with large aperture counts.


  • Quick turnaround for jobs with large aperture count
  • Smooth aperture walls, good paste release
  • Electroform foil provides higher paste transfer efficiency than uncoated laser cut stencils
  • Nickel formed foils that are laser cut offer better paste release than laser cut stainless foils
  • Electroform stencils have higher tensile strength and hardness than stainless steel stencils
  • Electroformed foils can be produced in non-standard thicknesses

Trapezoidal Aperture Walls:


1mil – 7mil
+/- 0.0003″
+/- 0.0004 over 10”
10×10″ area: within 0.001″ of original
16×16″: 0.0015″
20×20″: 0.002″
Taper is approx. 0.1 mils [0.0001″] per side per mil of foil thickness.  (E.g.) 5 mils thick foil would have ~ 0.5 mils taper per side
