Doyan manufactures SMT stencils since 2006. In strained condition with a cutting opening of 20µm, an aperture size accuracy of ±3µm and an aperture positioning accuracy of ±10µm, we guarantee we only produce the highest-quality SMT stencils. All laser cut SMT stencils undergo a brushing process to remove the minimal cutting burr on the laser exit side. This insures a constant stencil thickness of ±3% and no enlargement of apertures. For fine structures with an area ratio<0.66 we recommend the use of our nano-coating SMT stencil.
Doyan is the only manufacturer of Solder Paste Stencils in northern China. We use German LPKF SLG 6080 for a consistently high quality cut. The system has been specifically designed to manufacture stainless steel SMD solder paste and adhesive stencils. The result is a stencil of unsurpassed quality and accuracy.
