SMT Assembly Stencil Cleaners MicroCare SMT Assembly Stencil Cleaners are high-performance, high-yield cleaners, including stencil-wiping rolls, lint-free wipes, and pre-saturated alcohol wipes. MicroCare SMT Stencil Rolls are engineered for lead-free and fine-pitch applications. These rolls use a highly specialized fabric that is exceptionally strong and absorbent. MicroCare Presaturated Wipes from MicroCare are ideal for cleaning SMT stencils, PCBs, tools, plastic parts, metal cabinets and housings, work benches, and test equipment. They remove flux residues, solder paste, fingerprints, oils, grime, lint, and dust. All MicroCare pre-saturated wipes have an unlimited shelf life because a slam-shut lid keeps the wipes from drying out.
