Lead free flux removers are used to remove difficult lead free materials from PCBs. These fluxes require higher temperatures to reflow. Lead free fluxes and solder pastes also are prone to white residues. These fluxes require a cleaner formulated with aggressive solvency to fully remove the residues.
Removing no clean flux residues from PCBs is a special application. Most no clean fluxes are designed to remain uncleaned, and are more difficult to remove than old-style rosin-based fluxes. They are prone to leaving white residues and their activators can cause corrosion on the boards. These contaminates require a cleaner formulated with aggressive solvency, and possibly using inorganic fluids to fully remove any white residues. MicroCare offers several new formulations along with proven solvents that are strong candidates for these applications.
Rosin flux removers are a sub-set of general electronics cleaning. The cleaning and defluxing of traditional R, RMA, RA and SA fluxes is seeing a resurgence in the marketplace as the new no clean fluxes have not materialized into the economic panacea they were originally proclaimed. MicroCare offers a variety of solvents for flux removal on R, RA, RMA and SA fluxes.
Cleaning circuit boards and electronic assemblies is difficult. Today's PCBs run hotter, are smaller and more complex than ever before, so dendritic growth or corrosion can proliferate if the cleaning is not perfect. Aqueous systems simply cannot clean these components without higher spray pressures, extra cleaning agents and longer, more vigorous drying cycles, all of which add costs. In contrast, MicroCare offers a large family of specialty fluids which clean PCBs into the micron and sub-micron range. These fluids get under tight-fitting components and remove fluxes before they cause problems.
Stencil cleaning in SMT assembly is a high-risk, high-reward process, demanding the most from the solvents, wipes and tools. Proper stencil cleaning produces perfect PCBs. Inadequate stencil cleaning produces expensive junk. To achieve the highest yields from stencil cleaners, companies need the best cleaners with the best performance, global availability, a high degree of worker safety, and long-term material compatibilities. MicroCare has all these products.
Silicone removal is a particular problem for this remarkable industrial material. It often is used as an adhesive and as a protective conformal coating. These are very stable and resist acids, bases, solvents, chemicals, oils and water. But silicone can be difficult to handle and very hard to remove completely. MicroCare offers products for silicone removal, especially silicone conformal coatings.
Metal cleaning is complex and includes PCB components, jewelry, furniture frames, automotive trim, medical devices, and even household fixtures like faucets and doorknobs. The common need is to get metal components perfectly clean prior to painting, plating, welding or subsequent processing. Metal cleaning dissolves or displaces common soils metal finings, oils, inks, and/or waxes without damaging substrates. The process needs to be simple, fast and consistent. MicroCare offers a many solvents for metal cleaning.
Mass transit systems have very challenging cleaning environments. Subways, light rail systems, airport people-movers and city busses have a wide variety of cleaning problems: from simple grime and graffiti to cleaning complex electronics, removing protective coatings and refurbishing expensive traction motors. MicroCare has the answers companies need to clean better, faster and more reliably.
Mil-aero high reliability cleaning applications are often found in aerospace and military applications. To achieve the highest levels of performance, mil-aero components often have extremely complex shapes (which are hard to clean) and demanding environmental/performance specs, surviving extreme temperatures, out-gassing and performance in zero gravity. The high-purity, nonflammable cleaning fluids from MicroCare deliver highly reliability cleaning of crucial parts at the lowest possible cost-per-cleaning
Surface cleaning seems so simple just wipe it and it's clean but sometimes it's a critical issue. The need to clean work spaces, complex or expensive tools, soldering systems, racks and countertops mean that the best choices are needed, but they need to be affordable. The best choices will be nonflammable (for maximum safety), relatively fast-drying (to keep through-put up), environmentally benign, safe for people, and affordable. MicroCare can help.
Adhesive removal and cleaning glues, sticky residues and binders is a problem in manufacturing and repair across many industries. There are a wide variety of chemistries used in adhesives, from polyvinyl acetate, cyanoacrylates (Super glue), silicone adhesives, hot glues, polyurethanes and epoxies. Matching the adhesive to a solvent is easy with MicroCare adhesive removal fluids.
Ink removal is a very challenging industrial process. First, most inks are formulated to be permanent and durable. Additionally, inks are formulated from a wide variety of different fluids and chemistries; some inks are virtually indestructible. Finding a solvent that is safe for people and still has the cleaning power needed for ink removal without damaging the substrates can be a real challenge. MicroCare has a good range of creative answers
Removing water spots and water droplets from precision parts is a specialized form of precision cleaning called "solvent drying." If aqueous cleaning is used in a manufacturing process, solvent drying may be used as a final cleaning process to remove any residual water plus any residual contamination. This prevents water spots from forming. There are two entirely different methods of solvent drying. Absorption drying works well when the quantity of water is small; displacement cleaning is a better option for very wet applications.
