How to choose these electronics tools

soldering iron, soldering iron

When choosing a good soldering iron, you should take into account a series of characteristics that will determine if it is a good purchase or not:

  • Power: To use it as a hobby you can buy a lower power one, such as 30W. However, for professional use it should not be less than 60W. This will also affect the maximum temperature it will reach and the speed with which it will heat up.
  • Temperature adjustment: Many of the cheaper ones or for non-professional use do not have it. But the most advanced ones do allow it. This is positive, to modify the temperature and adapt it to the work you do.
  • Interchangeable tips: It is the best option, since when they are damaged, they can be easily changed for others. Or, better yet, when another type of tip is needed, it can be quickly changed.
  • Mounting: the handle must be ergonomic, have a good grip, and insulate well from the heat to avoid burns. The grips are usually made of silicone or TPU with engravings to improve grip.
  • Briefcase or case: If you plan to carry your tin soldering iron from one place to another, you should think about looking for one that is compact and that you can easily carry in its box.
  • dissipation system: Some include dissipation systems to help cool the tip so it can be stored more quickly.
  • Wireless or wired: the wireless ones are very practical, providing freedom of movement, without ties. However, the ones that provide the best performance and power are the cable ones. Cable ones are also usually more durable and reliable.
  • Extras: some also include a heat pump for desoldering, support to leave it when it is hot, accessory for cleaning the tip, LCD screen to see the temperature, etc. All this can be additional points, although it is not the most important.

How to choose the tin to solder

As for the choose the best tin For soldering, the first thing you should know is that the current options are lead-free, since it is a fairly toxic metal. Now they use other alloys, and they usually have a core of Colofina (resin), which helps during welding to penetrate well in all corners when heated and flow, improves adherence, the fluidity of the tin itself, and improves welding.

  • Manufacturer: There are notable brands, with better quality, such as JBC and Fixpoint.
  • Format: you have it in coils, which is the most common, and also options in supports, more expensive but practical to use.
  • Appearance: Look at the appearance of the tin wire, it should look bright and vivid.
  • flux cored: the resin, flux or rosin, comes inside the wire. A hollow thread, with flux inside it to improve results.
  • Diameter: there are from the finest to thicker, such as 1.5mm. Each one is valid for one application. For example, the thinner one will work for smaller items, while the larger ones might work for soldering wires and other larger components.
  • Unleaded: Must not contain lead. Before they used to be 60% Sn and 38% Pb.
  • Composition:: you can find them compounds with various proportions, which are usually composed of Sn and small amounts of Cu and/or Ag.

How to solder tin properly

Board Tin Electronics Soldering Station Soldering Iron

Explaining the steps to good soldering is easy, however it takes practice. You should start with a broken PCB and try to solder components to get the necessary experience, and that the solders come out better and better. Go soldering smaller and more complicated components, and in the end you will get it. Among the steps to take for soldering are:

  1. Prepare all the pieces you need, as well as the tools, protection elements, etc.
  2. All surfaces must be very clean, including the soldering iron tip.
  3. Heat up the soldering iron until it is at the right temperature.
  4. One piece of advice is to tin the pieces or parts to be soldered separately (the tip of the soldering iron must also be tin plated). That is, use the soldering iron to heat the ends and put some tin. This will result in a more homogeneous union.
  5. Then, join both parts, ensuring that they are well held in the right place. Avoid that they are in contact with other elements with which it can interfere, etc.
  6. Now heat and tin the joint, bringing the tin wire closer to the joint area. Remember that the tin wire cannot touch the tip directly, but rather the tip must touch the area to be soldered to heat it and then touch that area with the tin to tin it.

It seems simple, but it is not so in practice, since the solder should be:

  • Sparkly: if it has impurities or a dull color, it will be indicating that it is of poor quality, and that it was made at too low a temperature.
  • Just the right size: it should be enough to bond the components together, but there should be no globs or excesses, even if they are not shorting out another circuit element.
  • Resistant: It must be robust, without being able to easily break due to vibrations or thermal stresses.

In addition, you should use the tips of a pair of pliers or something similar to grab the terminal of the component to be soldered (if possible), between the solder area and the component, to try to dissipate some heat and that the high temperature does not damage the component.

Common problems and mistakes when welding

Between the most common mistakes that are usually committed during soldering of tin include:

  • Not fixing the elements well and causing them to move, preventing you from welding properly.
  • The tip of the soldering iron touches the tin.
  • Do not tin before use.
  • Not using the right tip.
  • Position the soldering iron tip too vertically. (It must be more horizontal to increase the surface that is in contact)
  • Do not wait a few seconds for the tin to solidify properly.
  • Not cleaning the work area to be welded. (alcohol and a lint-free cotton can be used and if what is left is traces of previous soldering, then use the desoldering iron)
  • Using sandpaper to clean the soldering iron tip, damaging the surface and making it unusable.

welder maintenance

maintenance

It is important keep the welder in good condition. In this way it will always be available to do a good job, and we will extend its useful life. To keep it in good condition, it is as simple as:

  • Store the soldering iron in a correct place, always waiting for it to cool down completely.
  • Avoid winding the cable or pulling it.
  • Clean the tip of the soldering iron or soldering iron correctly:
    1. Use the sponges or cleaners mentioned above (damp sponge, or copper braid) to rub the hot tip over them and remove any debris or impurities it may have.
    2. If it is still not clean enough, you can use a cleaning liquid such as flux. The tip must be hot, it dips and moves. In this way the rust is removed.
    3. If it still looks bad, it's time to change the tip.
