The Soldering Machine is extremely efficient. One Soldering Machine plus a screen printing table and two workers can complete nearly 100 PCB boards in the largest size in one day, and thousands of PCB boards in the small size. The Soldering Machine has changed the practice that the Soldering Machine can only rely on natural cooling or pulling out the PCB board for cooling outside the Soldering Machine, making the reflow soldering process curve more perfect and avoiding the damage of surface mount devices and the problem of soldering displacement.
How to use Soldering Machine correctly?
How to properly maintain Soldering Machine?
What is the capillary action of the Soldering Machine?
1. The soldering time of the Soldering Machine should not be too long, otherwise the components will be easily scalded. If necessary, clamp the pins with tweezers to help dissipate heat.
2. The solder joint of the Soldering Machine should be in the shape of a sine wave, the surface should be bright and smooth, without tin thorns, and the amount of tin should be moderate.
3. After the Soldering Machine is completed, the residual flux on the circuit board should be cleaned with alcohol to prevent the carbonized flux from affecting the normal operation of the circuit.
4. The integrated circuit should be soldered last, and the electric soldering iron should be grounded reliably, or the residual heat should be used for welding after power off. Or use a special socket for integrated circuits, and then plug the integrated circuit in after soldering the socket.
5. The Soldering Machine should be placed on the soldering iron stand.
When soldering the Soldering Machine, the solder joints should not be too saturated. If the solder joints are too large, it is easy to open the circuit with the adjacent solder joints. When soldering, the solder joints should not be too tin-saving, so that the situation of virtual soldering often occurs. The correct solder joint of the Soldering Machine is in the middle of three or four points. The solder should be in a small semi-circle with the component feet, and it is not saturated and does not save tin. It seems that the contact between the solder joint and the component is the best, and the soldered circuit The boards are also the neatest. It is better to use an adjustable constant temperature soldering iron for the Soldering Machine; when the soldering iron is not usually used, a certain amount of tin should be kept on the tip of the soldering iron. Measure the amount of water until the sponge is wet all day; when you pick up the soldering iron and start using it, you need to clean the tip of the soldering iron.
For example, after two clean metal surfaces are combined and immersed in molten solder, the solder will wet the two metal surfaces and climb up to fill the gap between the adjacent surfaces. This is capillary action. If the metal surface is not clean, there is no wetting and capillary action and the solder will not fill the spot. When the printed circuit board plated with through-holes passes through the wave crest furnace, it is the force of capillary action that fills the hole with tin and forms a so-called "solder ribbon" on the printed circuit board of the Soldering Machine.
