• Nickel Stencils
  Improvements in Pb-free Stencils
  When screen printing with Pb-free solder pastes, stencils made from pure nickel or a nickel alloy help to achieve paste transfer efficiency comparable to the levels achieved using SnPb pastes with stainless steel laser-cut stencils. Combined with the efficiencies of a framemounted interchangeable foil stencil system, nickel is the optimal medium for process repeatability and productivity.
