Most Common Mistakes & Their Solution During Soldering

The soldering process is one of the technical and complicated processes. Suppose we do not follow the correct rules( soldering temperature, solder size and type, and best soldering iron) of the soldering. In that case, the soldering of the components on the circuit board or any other material will not only damage that component but may also damage the whole circuit board. There are some common mistakes during soldering, which are mentioned below with their solution.

Soldering is a joining process used to join various metals, plastic, and other materials together by liquefying metals/solder. Bind is a metal amalgam typically made of tin and lead, dissolved utilizing a hot iron. The iron is warmed to temperatures over 600 degrees Fahrenheit, which then, at that point, cools to make a solid electrical bond.

Mistakes During Soldering

  • The most frequent mistake is placing the soldering iron on the work surface, neglecting an essential aspect: safety and danger.

  • Another most common mistake that cleaning tips using an invasive system OR using abrasive paper for cleaning tips.
Sand Paper
  • This is a common mistake: I think it’s easy to blend tin into the copper wire without using new tin.

  • The most common mistake in tin soldering is to solder the components without adding tin to the tip.

  • Another most common mistake is that soldering two elements without pre- thinning the surface or the copper wire.
Pre-Tinning
  • Cooling the tip quickly when it is at working temperature is to immerse it in cold water.

  • Try to solder with the presence of oxide.

  • The most dangerous mistake is inhaling the fumes during the soldering.

  • Using large tips for small components. It is wrong and risky

  • Dont respect the right temperature, melting of the coating materials.

  • Another common mistake is using the wrong tine size and bad solder, which damage the components.

Solution Of Mistakes

  • Placing the soldering iron on its support costs nothing but above all, you will avoid burning your hand or damaging other things in your work area.

  • Use a special abrasive sponge, but you have to use it wisely, just pass it gently to remove the dirt or tin. OR use a sponge soaked in water to avoid taking risks.

  • Always you have to use new tin/solder wire because you need the flux which is inside the tin.
  • When you have to solder always have to put the clean tin on the tip in order to speed up the soldering process. The tin added to the tip will act as a thermal conductor exposing much more surface to heat.

  • Always put tin on the wire before soldering into the connector.

  • Let your welder cool down through the natural cooling process. if you need speed cooling then use a thick cloth for cooling instead of cold water

  • Remove/clean the oxide with an abrasive sponge, once the oxide has been removed, The tin can easily adhere to the surface.

  • Use the exhaust fan or the activated carbon filter. To avoid the fumes reaching your face.
