circuit board manual soldering with five steps operation methods

There are two types of manual soldering operations for PCB printed circuit board electronics.One is the five-step welding method, and the other is the three-step welding method.Next, the staff of the PCB factory will introduce how to learn the five-step welding method.The specific operation steps are as follows:

The first step is to prepare for welding: first check the soldering iron before welding, the soldering tip should be kept clean and in the tin status, that is status ready for welding.In general, the left hand to take the soldering wire, the right hand to take the electric soldering iron, soldering tip and soldering wire close to each other, it’s welding status at any time, at the same time identify the location.

The second step is heating weldment: welding head for welding components of the solder joint, contact on the tin soldering iron head along the Angle of 45 ° in the direction of the stick close by welding components leads to heating, warming solder joints.

The third step is to melt solder: components after heated to the temperature of the molten solder, lead along 45 ° direction in a timely manner to solder wire from the side of the welding head touches the surface of the welding place, contact welding melting solder in moderation.

The fourth step is to remove the solder wire: melt the right amount of solder wire and quickly remove the wire.

The fifth step is to remove soldering iron:the welding point solder is close to the plump, solder wire fully infiltrates welding plate and weldment, soldering left Angle of 45 ° direction, so that we can form a bright smooth welds joint, the welding process a solder joint time is better not longer than  3-5 seconds .
