The 10-5L is a 5ft Chem-Wik® Rosin SD Desoldering Braid especially designed for heat and static 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, minimizing overheating and requiring less contact pressure for greater operator control and are coated with a type-R organic flux system.
