In the selective soldering process, dross can be detrimental. Dross (and I use this term to encompass all surface contamination) is created in conjunction with the presence of Oxygen in two different areas of the process, and by separate means. Each must be dealt with differently in order to prevent problems.
This unique method simplifies the rework process allowing the stencil get in to tight spaces, get higher first pass yields as the paste processing window is much wider than with metal stencils.
These rework one-time-use stencils are ideal for connectors, QFPs, and other areas on the PCB requiring rework. They may be designed with or without a solder paste boarder surrounding the area to be reworked.
