- Micro-fine pattern on stencil squeegee side
- Enhanced paste roll
- Improved aperture fill
- Ideal for lead free production
Paste roll activation (PRA) is provided by the inclusion of a micro-fine pattern on the stencil squeegee side. Although effective paste roll will depend on the diameter of the paste bead used, significant enhancements are evident using the PRA pattern. An additional benefit offered is that paste mixing and conditioning is improved to increase the capability of the paste itself.
Effective paste roll is an important pre-requisite for successful solder paste printing and the PRA pattern encourages paste roll within 5mm to 10mm of the start of the printing stroke, thereby reducing the run-on and run-off distances which ultimately increases the print area. The PRA pattern delivers a better aperture filling capability than non-PRA stencils and is proven to be particularly beneficial for fine pitch applications in both leaded and lead-free production.
