The 7-25L is a green Chem-Wik® Rosin Desoldering Braid designed for today's heat sensitive electronic components. The lighter mass, pure copper braid construction allows for better thermal conductivity, even at low temperatures. Chem-Wik® Rosin responds as much as 50% faster than conventional desoldering braids. This design minimizes overheating and requires less contact pressure for greater operator control. All sizes are coated with a type R organic flux system. The Chem-Wik® Rosin desoldering braid safely removes solder from through-hole components, surface mount device pads, BGA pads, micro circuits, terminals, identification script, lugs and posts.
