For electronic enthusiasts amateur production of some circuit boards, they can only be hand-welded by themselves, welding one or two pieces generally no problem, but occasionally welding 10 pieces, it may not be so good, and want to weld well We must first understand the circuit board soldering techniques , the following small series briefly introduces the soldering techniques of the circuit board .
·Step 1 of the circuit board soldering technique
First, heat the soldering iron and heat it until it is just enough to melt the solder. Then, apply the soldering flux to the soldering iron. Spread the solder evenly on the iron head of the Aetsen soldering iron until a thin layer of bright tin is formed on the surface of the soldering iron. Yes.
Secondly, during the more general welding, one hand holds the electric iron and the other hand holds the solder wire, which is close to each other. The soldering iron head touches the root of the solder wire gently to form a solder joint.
Then, in the welding process, the welding time should not be too long. If the welding time is too long, the welding element can be easily burned, and if necessary, an auxiliary tool can be used. Finally, the soldering iron should be placed on the iron frame.
·Step 2 of the soldering technique of the circuit board
The welding sequence of the components shall be in accordance with the order of the first post-implantation and the first order shall be low and high. Take the chip-intensive integrated chip, this is a difficult place in the welding process, if the welding is difficult on the final welding, if welding defects, resulting in damage to the pad, then the previous efforts It's all gone. Therefore, the order of the first to be difficult is still very much based on the actual situation.
As to why the first low and high, the first post-installation after the patch is because this is more convenient when welding. If there are many high-level components on the circuit, if components with higher heights are first soldered, it will be inconvenient to solder components with lower heights. If the first component is soldered and then soldered, the circuit board will be uneven on the soldering station during welding, resulting in welding defects.
The relevant information on circuit board soldering techniques has been introduced here for everyone. I hope this article will help you. If you still have anything you don’t understand, you can follow our website and we’ll get back to you as soon as possible.
