Soldering machine manufacturers can be divided into four categories according to the total number of welding heads: single-head automatic soldering machine, double-head soldering machine, three-head soldering machine, multi-head soldering machine, visual soldering system is the core element of visual soldering machine,
Soldering machine manufacturers can be divided into two categories according to the form of solder: contact soldering machine - soldering iron welding machine, non-contact welding machine - laser soldering machine, automatic dispensing machine is widely used in semiconductor, electronic parts, LCD manufacturing and other fields.
There are many types and specifications of automatic soldering machines, and the size of the parts to be welded is not the same. Therefore, the effective use of the output power and type of automatic welding machine is directly related to the improvement of welding quality and efficiency. When welding integrated circuit chips, transistors and electronic devices that are susceptible to heat, 20W internal combustion or 25W external heat welding machines should be used.
Before using and working with the welding machine, the soldering iron should be heated, the solder can be coated with flux immediately after melting, and the solder is evenly coated on the soldering iron head, so that the soldering iron head can eat the tin evenly. The welding technique of the welding machine is to rub the pad and the matching pin with fine sandpaper and apply the flux flux. Use the soldering iron tip to dip an appropriate amount of solder, contact a solder joint, after the solder part of the solder joint is melted and immersed to affect the component lead, the electric soldering iron head along the pins of these components at the same time need to gently lift us to leave the solder joint.
The soldering time of the soldering machine should not be too long, otherwise it is easy to burn the components, if necessary, you can use tweezers to clamp the dowel to help cool. The solder joint of the soldering machine should be sinusoidal wave peak shape, the surface should be bright and smooth, Wuxi thorn, and the amount of tin is moderate.
