Made of high quality oxygen-free copper, fast conductance and heat resistance up to 480C for durable use Applicable to 936, 937 soldering station, etc., with its needle-shaped pointed end suitable for craft making, for example, suitable for a car alarm remote control If the use of the iron tip is appropriate, its duration lifespan can reach more than 20,000 solder joints. It has the advantage of long durable life and not easily oxidize, easy to install and use It has high security and stable performance. Quite easy to take and clean. Use the sponge to polish the surface. Please don't leave them exposed to air, better wrap them with tin Feature: Made of high quality oxygen-free copper which has a Fast conductance and heat resistance up to 480C for durable use. Applicable to soldering station 936, 937, etc., with its pointed needle-shaped end suitable for DIY making, for example, suitable for car alarm remote control, micro switches are more small than micro (smaller than a pinhead), or solder in a narrow space, revising the tin bridge emerging from the solder to the chip. This makes soldering these delicate, tighter connections much easier. If the use of iron tip is proper, its lifespan can reach more than 20000 solder joints. It has the advantage of long service life and is not easily oxidized, easy to install and use. It has high security and stable performance. Quite easy to take and clean. Use the sponge to polish the surface. Please don't leave them exposed to air, better wrap them with tin.
