Tinsugetråd - 1,9mm x 30MCHEM WIK is an advanced ultra thin desoldering wick that responds even faster than any other desoldering wick. It`s lighter gauge, pure copper braidconstruction allows better thermal conductivity, even at low temperatures. With CHEM WIK, overheating of critical heat sensitive components and circuits is minimized because it requires less heat for a shorter period of time. CHEM WIK also requires less " contact " pressure for greater operator comfort.
