Thermostatic soldering iron soldering precautions:
1, constant temperature soldering iron soldering iron head temperature should be appropriate, different temperature soldering iron head on the rosin block, will produce different phenomena, in general, the rosin melts faster and does not smoke when the temperature is more appropriate.
2, constant temperature soldering iron welding time should be appropriate, from heating the soldering point to the solder melting and flow full of soldering point, generally should be completed within a few seconds. If the welding time is too long, the welding point on the flux completely volatile, it lost the role of flux. Welding time is too short, the temperature of the welding point can not reach the welding temperature can not reach the welding temperature, the solder can not be fully melted, easy to cause false welding.
3, the use of solder and flux to the right amount, the general welding point of the solder and flux used too much or too little will cause a great impact on the welding quality.
4, to prevent arbitrary flow of solder on the soldering point, the ideal welding should be soldered only in the need to weld the place. In the welding operation, the beginning of the solder should be less, to be welded to the welding point to reach the welding temperature, solder flow into the welding point of the gap and then replenish the solder, quickly complete the welding.
5, constant temperature soldering iron welding process do not touch the welding point, in the welding point on the solder has not been completely solidified, should not move the welding point on the soldered devices and wires, otherwise the welding point to deformation, the phenomenon of virtual welding.
6, constant temperature soldering iron welding should not burn the surrounding components and wires, welding should be careful not to make the soldering iron hot around the wire of the plastic insulation layer and the surface of the components, especially the welding structure is more compact, the shape of the more complex products.
7, the welding is completed Timely and good welding after the removal of work, welding is completed, should be cut off the wire head and welding down the slag and other timely removal, to prevent falling into the product to bring hidden danger.
