SMT FOILS

SMT stencil foils perform the critical task of depositing solder paste, adhesive or flux onto the PCB. The material that the foil is made from influences its dimensional accuracy, solder paste release properties and useful life.

Datum is the market leader in SMT stencil foils because we revolutionised the technology within them. By studying the root causes of solder paste printing issues associated with foil materials, we developed HD. In 1996, this was the world’s first stress-relieved steel alloy specifically targeted to the laser-cut SMT stencil market. Then we developed  Datum PhD 304 Stainless Steel. Datum PhD’s innovative characteristics are its homogenous and recrystallised grain structure, which promotes cut – and therefore print – quality.

Our innovative approach to ever-changing technologies keeps us and our customers at the forefront of what’s possible.

Datum PhD 304 Stainless Steel

  • Market leading material for over a decade
    Proprietary rolling and heat treating relieves internal stresses, resulting in less deformation during laser cutting and stencil printing
  • Tightest thickness on the market – controls area ratio and volume variations during print process
  • Excellent for general SMT with area ratios >0.66
  • Thickness range – 0.02mm to 0.5mm

Datum FG (Fine Grain) 304 Stainless Steel

All foils re available pre-mounted on our frames, in coils or as sheets cut to standard and custom sizes. We can also ship stencil foils with pre-milled pockets or cavities ready for laser cutting and we can also process border hole patterns in the sheets ready to mount in tensioning systems.
