At present, there are many types of soldering iron tips in the domestic market, and the quality is different. It can be said that the flowers are in full bloom, how to distinguish the quality of the iron tip when buying the iron tip, I hope that it can help more people to better distinguish the quality of the iron tip, and buy the iron tip model you are satisfied with.
■ The reference factors for identifying the quality of the soldering iron tip are as follows:
1. The size and accuracy do not have to be as high as possible. What you need to care about are several key sizes, installation size and head size;
2. Shape, no need to consider the color of the shape, whatever he is black, bright, white, the color of the surface of the soldering iron head is basically for two purposes: anti-rust and anti-climbing tin, no matter what color, the most surface layer is definitely chrome , Chromium is just to prevent tin climbing;
3. Pinholes, the head of the soldering iron tip should be carefully checked for pinholes. If so, this soldering iron tip is definitely not a good thing;
4. Inner hole, iron tip with inner hole, the inner surface should be as smooth as possible;
5. Destruction, this is the most intuitive way to judge. Use a file to set the head open, and see if the base layer must be copper and the iron layer is thick, but not too thick. The thickness is between 0.8 and 1.1 mm.
6. Lead-free, if it is a lead-free soldering iron head, the pre-tin on the head may not be very good, because the flow of pure tin is not strong, and the appearance will look slightly black, if the pre-tin on the head is too bright and beautiful, Whether to guarantee lead-free should be discussed carefully.
In summary, the Jimei alloy soldering iron tip is made of German alloy material, non-electroplating, no perforation and no tin running. The choice of soldering iron tip is very important. How to choose a really good and cheap soldering iron tip is not enough to judge by appearance, the best method is to directly take samples and make a comparative trial on the production line.
