What is soldering soldering is a thermal process that has already been around 5000 V. Christ was used. This connection technique was already used during this time to make jewellery items made of gold, silver and copper. The solder is the connecting material, with this a metallic connection of two metallic components is created. Other connection techniques, for example, welding, gluing etc. is one of the electrical connection techniques, which types are available, for example, in soldering processes, cold soldering, diving joldering, vacuum soldering, which distinguishes soft soldering from brazing soft soldering up to 450 degrees, brazing from 450 degrees and above 900 degrees high temperature soldering. Soft soldering is often found in electrical engineering. Such as soldering circuit boards, cables, etc. The flux used is usually acid-free such as rosin. The diameter used in this process depends on the workpieces to be processed. A frequently used solder wire is 1 mm solder wire. What types of solder are there, metal solder can be solder paste, solder wire, etc. These usually contain a flux that serves to wetting the workpiece. If the purity grade of soldering is very high, such as semiconductor lasers, no flux is used, as this often leaves a residue on the solder joint. Silver solder is used in metallised ceramic parts, with glass solder used in ceramic and glass. Soldering wire lead-free. The use of soldering wire lead and other heavy metals is prohibited in electrical and electronic devices. This is to minimise risk for health and the environment. Therefore, replacement alloys such as Sn/Cu or Sn/AG/CU must be used. This insert increases the dangers of soldering. The soldering smoke that arise during soft soldering and the flux used which contain amongst other things, rosin ammonium chloris etc., can be very harmful to health. Therefore, ensure that you are wearing suitable protective clothing such as a breathing mask.
