Rosin soldering flux6/23/2023 ![]() Rosin flux helps you produce good solder joints, so this recipe lets you continue to do that with less risk to your health. When you’re done soldering, alcohol will clean the resin right off the PCB. When you’re ready to use the rosin flux, you can either apply it with a brush dipped in the jar or with a large gauge syringe. Sealing the jar will retain that consistency. Then either add alcohol or let the alcohol evaporate until you reach the desired consistency. ![]() Repeat that process until you have nice, clean resin that is free of particulates. You can achieve that by mixing in alcohol (many different types work, including standard rubbing alcohol) to lower the viscosity enough to strain the resin through a coffee filter into a clean glass jar. With either, the goal is to refine and filter the substance to produce clean rosin flux of the desired consistency. You can collect that yourself if you have pine trees nearby or you can buy rosin from a music shop. The chemicals in commercial rosin flux exist to either lower costs or improve performance, but aren’t completely necessary. It may be possible to reduce those symptoms by using natural ingredients. Long term exposure may even result in asthma or dermatitis. Reports on the dangers vary, but exposure to rosin flux fumes can irritate the nose, sinus, eyes, throat and skin in the short term. Different formulas exist, but typical rosin flux contains several chemicals that may be toxic. Hopefully you’ve already stopped using lead solder, but your rosin flux may still be dangerous. To provide a safer alternative, catsndogs came up with a recipe for rosin flux that uses natural ingredients. Rosin flux comes in handy for both types of soldering, but the chemicals in commercial rosin flux can cause health problems. Most people start with a soldering iron and through-hole components, then move onto more advanced hot air soldering with SMD (surface-mount device) components as needed. With the exception of some basic components that fit together with special connectors, almost every electronic project requires at least some soldering. This versatile flux offers the benefits of a rosin flux, with the unique advantage of being water-soluble.Īdditional Rosin Fluxes available, including Solderability Testing Flux to meet the specifications of J-STD-004 testing for rosin fluxes.Soldering is likely the most common skill among makers. 8600 Type RMA is a revolutionary rosin paste flux whose residues are completely water-soluble. If you need to remove oxidization from wires, a rosin-based solder is your best bet. ![]() 9000 meets all the requirements of Mil-F-14256C, Type RMA. 1.Use rosin-based flux for electrical soldering. It has excellent wetting ability and a stable viscosity, and is both halide-free and halogen-free. 9000 Type RMA rosin paste flux was formulated for industrial operating environments. 100HT Type RA liquid rosin flux is formulated using a special combination of activator and solvents to work in high temperature solder applications. 100 Type RA liquid rosin flux is an ideal activated rosin flux for soldering PCBs, wire, cable, and semiconductors. 99 can be used for automated and manual soldering applications, and meets all the requirements of Mil-F-14256C, Type RMA. 99 Type RMA liquid rosin flux is ideal for general purpose soldering of PCBs, wire, cable and semiconductors and hand-soldering applications. 97 can be used for automated and manual soldering applications and meets all the requirements of Mil-F-14256C, Type R. ![]() ![]() 97 is completely free of any activators and leaves a non-corrosive, non-conductive, fungus-proof post-solder residue. 97 Type R liquid rosin flux is ideal for general purpose soldering of PCBs, wire, cable and semiconductors, and hand-soldering applications. Type RA (Rosin Fully Activated): High activity rosin flux ideal for high lead alloys.This petroleum/rosin contains NO Zinc Chloride or Ammonium Chloride, making it a better choice for. Type RMA (Rosin Mildly Activated): Mildly activated rosin flux that contains no chlorides. The ideal flux for electrical and electronic repairs.Residues are non-corrosive and non-conductive. Type R (Rosin): Non-activated rosin flux for soldering copper. ![]()
