Generally speaking, the quality of thinner and brighter solder wire for automatic soldering robot is better, while the too thick solder wire has a higher lead content and is relatively difficult to melt. A good solder wire is white and shiny, and it is not easy to apply to the hands when wiped by hand. It is shiny and has no oxidation and blackening. However, the solder wire with high lead content is black. Wiping by hand is easy to get black hands! The hardness of solder wire is not high. Let’s take a look at the editor from Shenzhen Rui Chi –A specialized automatic soldering machine equipment manufacturer in Shenzhen, China.
The temperature of the soldering iron should be adjusted correctly before using the automatic soldering robot. If the temperature is too high or too low, the tin can not be tinned normally. The melting point is different depending on the amount and composition. The appropriate temperature must be adjusted to accurately detect , The tolerances is generally ±5 degrees.
The soldering iron cannot be tinned and the quality of the solder wire has nothing to do with it. The main reason is that the soldering iron tip is too dirty or the soldering tip quality is not good. You can rub the contact surface of the soldering tip or change to a good quality copper soldering iron tip. ; During the welding process, it can be judged according to the size of the solder fume, less fume means higher purity! After soldering, it can be identified based on the gloss of the solder joints. If the solder joints are relatively white, it means that the solder wire contains more lead and the quality of the solder wire is poor. It can also be judged according to the amount of tin dross remaining. The more tin dross means that the purity of the solder wire is not high, and the lead content can contain more metal elements! The lead-free solder wire must be judged according to whether it meets ROHS standards, flux residue, halogen-free, and soldering speed.
