How to make reliable soldering

How to make reliable soldering?,There are often cases when something needs to be solder someone stepped on a telephone cable, when you walked to the phone through the apartment, someone called you when you listened to music through headphones, and one of them is silent, the charger has stopped working, etc-are the cause of this may be, most likely, breakage, which can be eliminated by using soldering. How to make reliable soldering, do not let the broke up,and securely through time, we will cover in this article.

So, first you need to prepare surface, clear them from dirt, oxide film, fat, i.e. to make mechanical cleaning. Usually I do it using a hobby knife. If, for example, simply take the wire and carefully them first by removing the top layer of insulation. You can also use the sand paper (not for wires of course),  filed, etc. Fat better wash off or warm ethanol, 10%-s ‘ solution of soda.

How to make reliable soldering

There are times when soldering the surface mechanically unable, or difficult and long, if it is a large surface. This is usually some alloys, iron, various coatings on the gland, then the surface should be clean dissolved acid. Usually for copper and its alloys are taking 10% solution of hydrochloric acid, which is heated to 50-70° С.

When self-cleaning,i.e. surface apply a thin layer of Tin on top. This gives a clear guarantee that there are good traction with the surface and Tin increases the durability and tightness. For a better connection to the same Tin solder, you will sweat.

There are different types of solder: POS60, POS30, POS80 and others, they are used for different purposes. Solders with high content of Tin (POS60, POS80) have better conductivity and are used mostly in the electronic industry for soldering electrical connections. PIC stands for 60 as tin-lead solder, which is 60% Tin.

And solders with high content of lead (POS30)-the more Refractory metals and are used more for engineering purposes, the radiators, basins, thick cables, where high current passes, etc.

Oversized items, and small, too, it is advisable to fasten before soldering soldering is more qualitative surface does not have to solder is cooling. To do this, you can use clamps, wire and other supplies and accessories.

For high quality soldering mechanical cleaning is not enough, as the addition of more use and fluxes. Fluxes need to remove oxide build-up from the surface of the solder and compress the parts during soldering.

The easiest flux is Rosin, or alcohol solution of rosin. Before soldering them moisten with surface, thus solder is better. It is widely used to connect the wireless component supplied, electrical wires, and does not cause oxide wires.

With regard to acid fluxes (chloride zinc, a divorced hydrochloric acid etc.) they are very effective when brazing of steel or galvanized products, different alloys, but when applied, after soldering, it is necessary to wash them very carefully, otherwise they could cause, in the near future, a considerable corrosion of the metal.

In radio electronics acid fluxes do not apply, because it is difficult to wash them away,  the wires they can very quickly. Therefore, before something to sweat, look what kind of flux you use.

Also want to add that the industry produces many different fluxes from the complex composition and for different purposes, in the form of liquid or paste, but before you apply them it is necessary to get acquainted with their appointments.

And to make it easy to solder, and soldering, it is necessary to do to choose the right power soldering iron, solder must be well melted. For electric wires and wireless component supplied enough 25-40 Watt, for massive parts to-100, 200 or 500 Watts. Tip for cleaning soldering iron use powerful powder ammonium chloride.
