Rosin SMD Kit (63/37)

Precision SMD soldering kit combining Kester 63/37 eutectic solder wire (0.020"), Soder-Wick Size 2 desoldering braid (0.06"), and Kester 186 RMA flux pen. All three items use rosin-based flux chemistry for seamless compatibility. Designed for fine pitch QFP and SOIC rework, compact PCB assembly, and surface mount replacement where minimal thermal impact and sharp 183°C melting point prevent cold joints on delicate pads.

• Bundle Contents: 1x Kester 24-6337-0010 Sn63Pb37 Solder Wire + 1x Soder-Wick 80-2-5 Rosin Desoldering Braid + 1x Kester 186 RMA Rosin Flux Pen
• Kester 24-6337-0010: Sn63Pb37 eutectic alloy, 0.020 inch (0.5mm) diameter, 44 Rosin Activated flux, 1 lb spool, sharp eutectic melting point 183°C, minimizes cold joint risk on fine pitch SMD pads and compact boards
• Soder-Wick 80-2-5: Size 2 rosin flux desoldering braid, 0.06 inch (1.5mm) width, 5 foot spool, pure copper construction, precise solder removal from fine pitch SMD pads without thermal damage to adjacent components
• Kester 186 Flux Pen: Type RMA rosin flux, 10mL applicator, non-corrosive and non-conductive residue, high thermal stability, targeted flux application on individual SMD pads, QFP and SOIC leads, and fine pitch rework
• Flux Compatibility: All three items use rosin based chemistry, fully compatible with each other for integrated SMD rework workflows
• 63/37 vs 60/40: Eutectic 63/37 sharp 183°C melt vs 60/40 wider plastic range, 63/37 preferred where fast solidification and minimal cold joints matter most
• Best For: SMD soldering and rework, fine pitch QFP and SOIC component work, compact PCB assembly, surface mount component replacement, electronics prototyping on dense boards, precision rework requiring finest solder diameter and braid width
