Some PCB makers are using the dip-and-brush method to clean circuit boards during rework and repair. However this process doesn't allow you to easily rinse contamination off the PCBs after they are scrubbed.
Other companies use high-pressure aerosols to blast the contamination off the board, but that often wastes cleaning fluid due to overspray.
At MicroCare, we think the best way to clean PCBs is with the TriggerGrip™ cleaning system with a planet-friendly cleaning fluid. The TriggerGrip™ system allows you to obtain great cleaning quickly, easily and without a lot of chemical waste, even under tight-fitting BGA components.
For R, RA, RMA and SA fluxes and solder pastes, the best choices from MicroCare have high density, high Kb values, low surface tension and low viscosity. The best choices might be: the Heavy Duty Flux Remover — SuprClean™, the General Purpose Flux Remover and the Alcohol-Enhanced Flux Remover — ProClean™.
Messy aerosol sprays volatilize the cleaning fluid, exposing workers to fumes. The excess fluid also can puddle below the cleaning site, creating a flammability hazard if the solvent has flammable characteristics
