The soldering iron head of automatic soldering machine is mainly used for welding components and conductors。 There are different classifications for mechanical structure, function and usage。 A soldering iron head is a necessary tool for the manufacture of electronic components and electrical maintenance。 When using an automatic soldering machine for welding, it is often met with such a problem that the iron head is not SN。 For this case, the cause of this situation can be caused by other reasons besides the problem of the iron head itself。 The manufacturer will help you analyze the reason why the solder doesn't go to the tin。
The reason why the soldering iron head of automatic solder machine does not go to tin is analyzed.
1, the tin surface of the iron head is not on the iron head before the machine is used, and the temperature is too high when welding. It is easy to oxidize the tin surface on the iron head with the oxygen in the air. The quality of the tin wire is not qualified or the flux in the welding wire is interrupted, and the use is incorrect or the improper cleaning method is used.
2。 When the welding real-time temperature is over 350, and the soldering over more than 1 hours, the amount of tin on the iron head is too low。 The flux used is highly corrosive, which causes the rapid oxidation of the iron head and contact with the organic compounds such as plastic, lubricating oil or other compounds。
3, "dry burning" iron head, such as: intelligent temperature controller often open not to use, and the iron head surface of no tin, will cause rapid oxidation of the iron head, the use of neutral active flux, no timely cleaning of the oxide on the iron head.
