Features:* * Made of high-quality oxygen-free copper, which is fast conductivity and temperature resistance up to 480 degrees Celsius for use.* Applicable to 936, 937 and so on soldering station with pointed needle-shaped end, which is suitable for workmanship, such as fit for car alarm remote control like a micro switch popped out of a small circuit board, and the s on the micro switch are smaller than micro (Smaller than the pin head) or soldering in a narrow space, revision of the tin bridge coming out of chip soldering. Makes brazing these delicate, stronger joints much easier* If with proper use of iron drill, its service life can reach more than 20000 welding joints* It has the advantage of long service life and not easily oxidized, easy to install and operate* It has high safety and stable operation. Fairly easy to take and clean. Use a sponge to polish the surface.
