Employing both CNC and manual laser welding, Suron is capable of producing particularly intricate components. Solder Masks The use of solder masks is often essential in SMT assemblies. There is also solder mask around the holes to help prevent solder bridges. Laser marking is also possible if there is a solder mask on the surface of the material, as the laser can ablate the solder mask to reveal the underlying epoxy or metal layer if present for a contrasting mark. At the same time, the maximum size of a single solder void is limited by the dimensions of a single matrix segment. There are two main categories of BGAs based on the pitch and solder mask definition. The darker the color the darker the engraving. The machine can also be used for the direct photoimaging of the solder mask. JB weld seems like a much better solution. DIY Mini CNC Laser Engraver.
