Machinery industry regardless of what products are required for maintenance, automatic soldering machine is no exception, in the process of the solder operation we have to pay attention to matters;
1, first select the appropriate solder. If the welding electronic components, it should be used for low melting point solder.
2, and then select the appropriate flux. The general mixed seventy-five percent twenty-five percent flux rosin alcohol.
3, tin soldering machine method is: first electric iron is heated to a certain temperature, so that it can just melt the solder, coated with flux, solder evenly coated on the soldering iron head.
4, pay attention to the solder welding method. The first pad and the assembly pin with fine sand coated with flux. And then use the soldering iron head picks up a small amount of solder contact pads, wait until the solder joints of all melted and immersion component lead head, soldering iron head along the components of the pin and gently to a left solder joint.
5, automatic soldering machine, the welding time should not be too long, otherwise it may spoil the components, can use tweezers pins for radiation.
6, automatic solder joints should be a sinusoidal wave shape, the surface should be bright and smooth, Wuxi thorn, the amount of medium.
7, solder machine after the completion of welding, to use alcohol to circuit board on the residual flux cleaning clean, to prevent carbonization and the flux affect the circuit work normally.
8, the integrated circuit should be finally welding, soldering iron to reliable grounding, or power after the use of waste heat welding. Or the use of integrated circuit socket, socket and then plug the integrated circuit.
