Machines change people's lives. In the era of technological innovation in the 21st century, fully automated soldering machines have been popularized in various fields. Although the advantages of the soldering machine are many, such as labor cost and high efficiency, it is inevitable that problems will occur during the welding process, which will affect the quality of the product. Today, the small series of Orix lends to everyone the reason for the low quality of welding.
1. Cold welding. During the soldering process, the soldering iron temperature of the solder is too low or the heating time is insufficient, the solder is not completely melted or wetted, or the solder surface is not bright and cracked.
2. Excessive amount of solder, forming tin deposits of solder joints; if the amount of tin is too small, it is not enough to wrap solder joints
3. The solder on the surface of the solder joint forms a sharp tip. This is mostly due to insufficient heating temperature or too little flux, and improper angles when the soldering iron leaves the solder joint.
4. There is a layer of rosin between the solder and the component or the printing plate, resulting in poor electrical connection. If the rosin is insufficiently heated, there is a yellow-brown rosin film under the solder joint; when the heating temperature is too high, the rosin will turn black. For the two cases, the former can be repaired with a soldering iron. For those that have been carbonized, refill the tin, clean the soldered components or the printed surface, and re-solder.
5. Excessive soldering agent and excessive rosin residue around the solder joint. When a small amount of rosin remains, gently heat it with a soldering iron to allow the rosin to evaporate. You can also wipe off excess rosin or flux with a cotton ball dipped in absolute alcohol.
6. Solder bridge. Too much solder is used, causing a short circuit between the solder joints of the components. This is especially important when auto-welding ultra-small components and small printed circuit boards.
