.031" 60/40 Rosin Solder + Flux Remover Bundle

This Concorde Solder bundle pairs the Kester 24-6040-0027 tin lead 60/40 rosin solder wire with the Chemtronics ES835B flux remover to give you everything needed for a complete rosin flux soldering workflow. The 0.031 inch diameter wire offers precise control and a wider plastic range than eutectic formulations, making it well suited for drag soldering and larger joints where extra working time is valuable, while the 183 to 190 degree Celsius melting range delivers reliable wetting and strong joint quality. The ES835B aerosol features a fast drying formula with low surface tension and an integrated brush applicator, efficiently removing rosin, RMA, RA, and synthetic flux residue to restore board cleanliness after soldering. Together they eliminate the need to source solder and cleanup separately, making this bundle the practical choice for PCB assembly, electronics rework, through hole soldering, and general repair work wherever a rosin flux soldering workflow and post solder board cleanup are part of your process.

• Bundle Contents: 1x Kester 24-6040-0027 Sn60Pb40 Solder Wire + 1x Chemtronics ES835B Flux Off Rosin Aerosol
• Kester 24-6040-0027: Sn60Pb40 alloy, 0.031 inch (0.8mm) diameter, 66/44 Rosin flux, melting range 183 to 190°C, wider plastic range suited for drag soldering and larger joints, post-solder cleaning required
• Chemtronics ES835B: Flux Off Rosin fast drying aerosol, removes rosin, RMA, RA, and synthetic flux residue, low surface tension for thorough penetration, integrated brush applicator
• Together: Solder and cleanup covered in one rosin flux bundle, essential two item pairing for a complete rosin workflow
• 60/40 vs 63/37: Wider plastic range (183 to 190°C) vs sharp eutectic 183°C melt, preferred by some technicians for drag soldering and larger joints where working time helps
• Best For: PCB assembly, electronics rework, through hole soldering, drag soldering, general electronics repair, rosin flux workflows where post solder board cleanup is required
