Why doesn't the soldering iron touch the tin?
What kind of electric iron are you?
It is OK to glue bit of colophony first, also can buy the silk that has colophony to use directly
The reason why electric soldering iron doesn't stick with tin and the way to solve it. Sometimes the soldering iron doesn't stick to tin in the lead free soldering process. This kind of circumstance removes the quality problem of electric soldering iron head oneself, we still can come from other nine respects to look for a reason: 1, choose the temperature is too high, easy to make electric soldering iron head to touch tin noodles to produce intense oxidation. 2 、 tin tin is not eaten before use. 3 、 use incorrect or defective cleaning methods. 4 、 use impure solder or solder flux in the welding wire to be interrupted. 5, when the working temperature exceeds 350 degrees, and stop welding more than 1 hours, lead-free soldering iron tin is too small. 6, "dry" electric iron head, such as: welding table open, not used, and the electric soldering iron surface top tin, will cause electric iron head rapid oxidation. 7, the use of flux is highly corrosive, causing rapid oxidation of the electric iron head; 8, the use of neutral flux activity, not to clean the iron tip oxide 9, exposed to organic materials such as plastic, oil or other compounds. Conventional treatment: scraping the electric iron head oxide layer with a knife to reveal copper that has not been oxidized by air. Then put it in the rosin box and dip it into the tin, and then you can use it properly. But this method of cleaning is not complete, and at the same time, long blow down, the tip will become thinner and affect heat transfer, leading to temperature drops, or even damage to the tip of the iron. Fast and efficient processing method is: holding electric iron wooden handle, the container is oxidized and the tip immersed filled with alcohol, after 1 ~ 2 minutes, completely and cleanly remove oxide, iron Tsui take on an altogether new aspect. This is because copper oxide and alcohol are heated to produce a chemical reaction, and copper is reduced, which does not corrode the electric iron head.
