If you need to solder out several parts, the design of which consists of a large number of contacts, you need to follow some basic aspects. Such parts include microcircuits, line transformers, variable resistors, etc.
It is necessary
- - electric soldering iron;
- - coil with copper braid;
- - desoldering pump.
Instructions
Step 1
One of the most affordable ways to uniformly extract radio components from circuit diagrams is to use a copper braid. It is a network of thin wires (copper). Usually, the braid can be found in any store with radio components on a plastic coil.
Step 2
The braid is only useful when it is necessary to "pick up" a large amount of solder drops from the part to be soldered. Why is copper and network connection used. When heated with a soldering iron, the copper will not melt, and the net has an absorbent effect, like the loops of a terry towel.
Step 3
Surely you know that any product can be of both good and bad quality. Sometimes there is a braid that looks like a flattened leaf of a holly plant. Such a winding is considered to be of poor quality. Most likely, this coil will reduce performance, so it needs to be slightly improved. To do this, use any sharp object and slightly gut the winding.
Step 4
To soften the main wire, it is recommended to plunge it with a special rosin solution, for example, a liquid flux. It is also possible to use coarse lump rosin - more of it will be required and the effect will be less noticeable. The only drawback of this technology is the constant consumption of copper braid.
Step 5
The device "Desoldering pump" can become an analogue of coils with a sheath. From the name of this unit, you can understand the essence of its application. Solder is composed of a mixture of lead and tin, hence the name. The second name of this device is "Desolder", which means "solder removal" in English. The principle of its operation consists in heating the contacts of the parts and sucking the solder into a special reservoir using a piston system.
