There are times when a PCB prototype needs to be built quickly to test out a design. In such cases where it is known early on that there will be multiple iterations or that a "one and done" assembly will be made that there will be some SMT assemblers who choose to hand print solder paste onto the board using a "frameless" stencil. In such cases where hand printing is used, the consistency of the printing technique has typically been in question. Furthermore, the effectiveness of both the nanocoatings as well as the higher end stainless steel materials, which have been heretofore studied in controlled printing environments, will be evaluated for their impact on the hand printing process.The purpose of the study was to determine the effectiveness of select nanocoating materials as well as certain high end stainless steel stencil materials as they relate to the manual SMT printing process. A variety of nanocoatings were applied to SMT metal stencils and solder paste volume measurements were taken to compare the effectiveness.
These can be used to roll solder paste through the stencil aperatures for prototype printing. One set custom made for stencil size. At soldertools.net we supply numerous types of metal stencils including framed, frameless and prototype stencils. We
This is video shows how to print a PCB using a prototype foil only stencil. The SMT prototype stencil (www.soldertools.net) is made from a high nickel content material able to offer repeatable high precision apertures. The steps of alignment, printin

These fixture plates facilitate the controlled dipping of flux or paste onto the balls under the BGA packages. Flux or paste is controlled at a depth of 50-60% per cent of the ball diameter prior to placement of a BGA or to place a PoP component on t
