Chemtronics Soder-Wick® Rosin Flux Desoldering Braid SW18045

Detailed Product Description

Chemtronics Soder-Wick® Rosin Flux Desoldering Braid [SW18045] is a high-performance, rosin-fluxed braided copper wick designed for professional and industrial electronic desoldering and rework applications.

Soder-Wick® features a lightweight, pure copper braid construction that provides excellent thermal conductivity and fast heat response, even at relatively low temperatures. This allows solder to be removed quickly while minimizing overheating and reducing the risk of PCB damage.

The product helps to:

• Remove excess solder from PCB assemblies
• Support electronic repair and rework operations
• Clean SMT and BGA pads effectively
• Remove solder quickly and efficiently
• Minimize overheating during desoldering
• Reduce the risk of PCB and component damage

Suitable for use with:

• Thru-hole components
• SMT pads and BGA pads
• Micro circuits
• Terminals
• Lugs and posts
• Identification script
