The 10-100L is a 100ft Chem-Wik® Rosin Desoldering Braid especially designed for heat sensitive electronic components. The lighter mass, pure copper braid construction allows for better thermal conductivity, even at low temperatures. It responds as much as 50% faster than conventional desoldering braids. This design minimizes overheating and requires less contact pressure for greater operator control and are coated with a type-R organic flux system.
