Method of hand soldering with defined and uniform soldering times during the soldering of lead-in wires to the assigned terminals of electric components by means of soldering wire

摘要

At the start of the soldering process, an electric circuit is closed by the contact between the assigned terminal 11 to be soldered of the component 1 and the soldering wire 4. The electric circuit starts an electric time base 8, which controls a visual display, advancing over an LED strip 9, in accordance with a preset period until an optical and/or acoustic signal is initiated at the end of the preset period.
