If you want to solder electronics, there are some important points to consider. Often boards offer little space, some of the components can withstand high temperatures for only a few seconds and not all soldering irons and solders have the optimal operating and melting temperatures. We will show you in this practice tip, what materials do you need for soldering of electronics, and give you tips for the soldering of electronic Parts.

Materials for electronics-soldering

For soldering electronics you need besides the electronics itself, of course, a soldering iron and solder. Pay attention to the following characteristics:
  • To solder electronics, you need to solder is soft. That is, the melting temperature of solder is below 450 degrees.
  • On the package by the solder, the composition is described. The Element is called, then the proportion in percent.
  • You use a solder with 60 percent Tin and 38 to 39 percent lead. So is the melting temperature of 180°C. In the image gallery we will show you how to use the composition of the packaging, the solder reading.
  • Solder with a diameter of 1 mm is ideally suited, 0.5 to 1.5 mm are also possible.
  • It is best to use a soldering iron with a 15 to 25 Watt.
  • Appropriate soldering iron tips are rather small and pointed. Very large and flat soldering iron tips, the look like a Flat-head screwdriver, are less suitable.
  • The tip of the soldering iron regularly to clean, you need a sponge. Caution: sponges made of foam, such as pot sponges, are unsuitable. Melt them under the hot soldering iron away and pollute him, instead of cleaning it.
  • Excess legs and cut after the soldering with a special side-cutters for electronics from.
  • Before soldering, you can many electronics Circuits to a breadboard or with Krokos test.

Tips for electronic soldering

To solder electronics, you have to work, sometimes quite quickly. With the following tips, you have a good place to start:
  • Insert components into the circuit Board and do not bend, then the legs, so that the device stays in place.
  • Wrap a few inches of solder from the roll.
  • You have purchased a kit, soldering them in the order recommended by the instructions.
  • You heat up the parts you want to connect. You touch your soldering iron to the components or the component and the solder Pad, it is for two to three seconds.
  • You have to aim now with the solder on the connection between the soldering iron and the components.
  • You give so much solder on the connection that it spans between the two wires, or the wire in the solder Pad completely from the Lot is wrapped.
  • Unplug the soldering iron and do not move the parts for the next few seconds.
  • Cut the excess leg part as directly as possible on the Lot.
  • Some components, such as Diodes, ICs and Transistors are sensitive to heat. You need to be quickly soldered.
  • Solder these parts first, if you already have a bit of Practice to cables, connectors or resistors have collected.
  • If the space allows it, you can attach to the leg of the sensitive device a pair of pliers or Crocodile clip, which serves as a conductor of heat.

The composition of solder is encoded on the package. Bp means lead, Sn is Tin, Cu for copper, and Ag for silver. Behind the share is in percent. Solder with 60 percent Tin and 38, or 39 per cent lead is "SN60BP38" or "SN60BP39". In the case of pure copper, you irritating, by the way, black: The melting temperature is 1083°C.

A bit more expensive, but for beginners a little safer: soldering Stations with adjustable temperature help you not to overheat the components. 300 to 350°C are optimal.
