What are the differences in the functions of soldering iron tips with different shapes
Release Date：2017-07-12
The shapes of soldering iron tips include pointed chisel shaped, blade shaped, and horseshoe shaped. The editor of Yapude summarizes the differences between these three different shapes of soldering iron tips.
Sharp tip soldering iron tip: A pointed soldering iron is suitable for welding small parts due to its small heating surface at the tip. It is only suitable for welding small parts and can also be used for mobile phone repair. Due to its small heating area, the welding table often needs to be heated to a higher temperature in order to weld well.
Knife head: The blade head is relatively easy to use and is most suitable for soldering multi legged chip chips. Scratching and soldering are very smooth, and the soldering speed of the chip is fast. After soldering the chip with a hot air gun, using the blade head for repair soldering is both fast and good. Similarly, the tip of a blade can also be used to weld small parts, so I have seen many skilled laptop repairers even using this type of soldering iron tip to weld both chips and small parts, with larger parts being easier to weld.
Horseshoe Head: The horseshoe head is widely recognized as the most user-friendly, and most electronics factory technicians use this type of soldering station. The horseshoe soldering iron is most suitable for soldering with drag soldering. Due to its large heating surface, it can instantly melt the solder at a very low temperature. Therefore, after dipping a horseshoe head in rosin, the rosin evaporates very little in a short period of time (because of the low temperature), so using it to solder chips is very efficient. For example, when soldering multi pin chips, the soldering iron tip is dipped in rosin and then soldered with solder wire from left to right. Due to the assistance of rosin, bridging rarely occurs halfway. After dragging to the far right, the soldering iron tip is wiped clean to absorb excess solder, and the reliability of soldering is very high.
