Manual soldering has for good reason outlived its usefulness and has been replaced by selective soldering

Factories are wonderful things when what they produce is shoes or food, for instance, but with manual soldering, however, things look somewhat different. That is associated with the fact that a good solder joint as an electrical or mechanical connection is distinguished by the following features: It works best on startup, it is created at as low a temperature as possible and it is finished as quickly as possible. These assumptions apply to manual soldering and to all other soldering techniques, even if the solder has changed from Sn63/PB37 to lead-free SAC305 or SN100 solder or the like. That a good soldering iron and the relevant skill suffice for manual soldering is a statement that of course still holds true but unfortunately it lost its meaning long ago because manual soldering is simply out of date.

Manual soldering has long been outmoded

Increasing complexity and ever-higher quality standards have contributed to soldering by hand no longer being accepted as an adequate technique. Out of habit, out of the conviction that finishing everything “by hand” is still wonderfully precise, specialists in small service businesses and medium-sized businesses and even some people in big firms still tackle their work manually without knowing that they could make things much easier for themselves, for example with selective soldering.


Manual soldering versus selective soldering:

  • The manual technique is suitable only for genuine one-off solutions or for individual repair points.
  • The soldering result is only ever as good as the person who produces it. This is and remains the weak point.
  • Reproducibility is not guaranteed.
  • Extreme flux residues from manual soldering
  • Significantly higher localised thermal load because of the small soldering tip and hence only a small contact area
  • Manual soldering is not authorised for use in the automobile industry or its supply sector.
