Rework Stencils

PCB Rework is the business of BEST. We teach PCB rework. We perform PCB rework. We also use that expertise to fabricate PCB rework stencils.

PCB rework stencils attempt to reproduce the initial assembly process when a more complicated SMT component part needs to be placed and reflowed onto a PCB. These stencils are essentially separately-designed cut-outs of the area requiring rework. They are placed over the component location with solder paste being rolled through the apertures. Once this is completed the replacement component is placed into the solder "bricks" and reflowed. 

Many times this rework stencil requires some ingenuity in terms of holding the stencil into place. Different fixturing holders are able to maintain the location of the printing. In other cases the rework stencils are outfitted with holding flaps which also serve to limit the areas where solder paste can be printed.

The BEST PCB rework stencils are made from the same high grade, nickel content stainless steel that are regular-sized SMT stencils are fabricated from. This material. wth its small grain structure and heat withstand properties allows for the best possible solder paste release which means that the rework area only needs to be printed one time.

With a BEST rework stencil the experience of thousands of rework projects are built right into the design of the stencil. Couple this with attention to your specific order requirements from our customer care team and you will have a good BEST PCB rework experience.
