Mechanic UV559 No-Clean BGA Flux Paste

The Mechanic UV559 is a professional-grade, lead-free, no-clean solder flux paste formulated for precision electronics repair, PCB rework, and BGA/SMD soldering. Based on the RMA-559 formula, it combines high-quality alloyed powder with a resin-based pasty flux to promote excellent solder wetting, strong joint formation, and minimal residue — making it a go-to consumable for mobile phone technicians, board-level repair professionals, and electronics hobbyists alike.

UV559 is classified as a weakly acidic flux, delivering reliable oxide removal and enhanced tin flow without corroding pads, traces, or component leads. Any residue left after soldering is very light in colour, non-conductive, and non-corrosive, with a high surface insulation resistance (SIR) value that ensures it is safe to leave on precision PCBs and communication devices. It performs cleanly with minimal smoke and no pungent odour. Suitable for BGA reballing, CSP solder ball repair, SMT assembly, PGA rework, and general PCB soldering on smartphones, tablets, and computer motherboards. Compatible with both leaded and lead-free solder alloys.
