Three Special Notices for Automatic Soldering Machine

Automatic soldering machines are far ahead of manual soldering in terms of efficiency and precision. Even a skilled soldering master can't continue soldering for a long time with high precision and high strength like automated equipment. However, there are some basic skills and methods to be used when using automatic soldering machines. These techniques and methods will make you more familiar with automatic soldering machines and solder out perfect products.
First, master the heating time, the automatic soldering machine can directly set the warm-up time in the control panel:
Different heating speeds can be used for soldering. For example, the shape of the soldering iron tip is poor. When soldering large soldering irons with small soldering irons, we have to extend the time to meet the solder temperature requirements. Extending the heating time in most cases is detrimental to electronics assembly because:
1. The bonding layer of the solder joint deteriorates the solder joint performance due to heating for a long time exceeding a suitable thickness.
2, printed boards, plastics and other materials will be deformed and deteriorated when heated too much.
3. The performance changes or even fails after the components are heated.
4. The surface of the solder joint is oxidized due to flux volatilization and loss of protection.
Second, maintain a suitable temperature:
If high-temperature soldering iron is used to weld the solder joint in order to shorten the heating time, there is another problem: the solder in the solder wire does not have enough time to flow over the soldered surface and volatilizes prematurely; the solder melts too fast. Affect the role of the flux; due to the high temperature, the heating time is short, which also causes overheating.
Third, the correct position correction of the soldering iron:
The force applied to the solder joint by the soldering iron will cause damage to the weldment, and the serious one will be scrapped as a product.
In addition to the above three points for the automatic soldering machine to pay special attention to the operation skills, there are some common methods in the soldering operation, such as the treatment of the surface of the weldment, pre-welding before welding, keeping the iron head clean, welding The pieces must be firm, etc. These are the necessary knowledge of some solder operators.
