[Model] 900M-TI Outer Diameter: Approx. 6.7mm / 0.26" Inner Diameter: Approx. 4.0mm / 0.16" Length: Approx. 43cm / 16.93" [Good Quality Material] This indicates high heat fast and 480 heat resistant for long time using.Yes,with good use of the tip of the iron,its service life can reach over 20,000 solder joints. [Features] This tip has the advantage of long service life and is not easy to rust, easy to install and use. [Applicable] This tip applies to soldering stations 936, 937, etc. of the micro switches would have detached from the small printed circuit board and the microswitch contacts are smaller than those of the microphones. Description: These iron tips are made of electrolytic iron and nickel which protect them from oxidation, characterized by Heat resistance up to 480 C and a lifespan of over 20,000 solder joints with proper use. Like the the tip is very sharp, it is suitable for manual finishing, for example with car problems, once micro the switch had popped out of the small printed circuit, you noticed that the contacts of the micro switch are smaller than micro (smaller than a pinhead) or solder in a tight space, also around the . to be revised Tin bridge made of solder to the chip. How about get this set and make your soldering work easier?
