Our Theme

When hot bar soldering, components are precisely and quickly soldered together:

Our Hot Bar Soldering Technology in the Industrial Production
  • Insert parts (tin depot + flux on the connections)
  • Parts are pressed together with cold thermode
  • Thermode is heated up
  • The tin melting creates a eutectic connection
  • Thermode and solder joint are cooled down
  • Cold thermode lifts off, solder joint is made
  • Remove parts - Completed!
Our Hot Bar Soldering Technology in the Industrial Production
The Initial Idea
When soldering in todays systems voltage currents of about 250 amps, correspond to the heating of the soldering iron. The power is generated in a special power supply and the soldering head is then connected to it with a thick feed line. This cable has a diameter of about 10mm, is absolutely inflexible and the crossing points, such as e.g. clamping connections on the soldering iron, connections to the power supply unit and any transitional connections are all warm, ultimately leading to power losses and leading to cable breaks after a short time.

Conventional soldering head of other manufacturers. You can see the thick feed lines to the thermode.

We wanted a soldering head, which has a flexible supply line, is nevertheless controlled as we know it today, which has no line losses and thus can heat up faster accordingly: The basic idea for our hot bar soldering generator was born.
Important Informationen:
As with all soldering processes, fl ux is also required for soldering. When soldering a previously applied tin deposit is melted and ensures an eutectic solder joint. For this purpose, flux should first be applied to one side.


Note: Lot depots, which were made from reflowed solder pastes (in the SMD assembly after reflow soldering), still have enough flux residues that a new soldering process (here soldering) sufficiently support - additional flux need not be applied.

The Advantage of Our Technology
Unlike other standard systems, we do not need a foil protector for the thermode. These films protect on other systems, the on-board electronics and on the other side the wear and tear of the thermode.

These measures are necessary because the thermodes are operated with voltages of several volts. Semiconductors switch on at voltages above 0.7 volts and, if necessary, allow currents to flow during the soldering process that are not provided in this way and that lead to damage.

In our technology, the thermode voltage is much lower!
The higher thermode voltage in other systems also leads to an electrolysis process associated with the flux. Here, too, due to the increased thermode voltage, this electrolysis is initiated, in which ultimately the thermode in the surface is slightly dissolved and undergoes noticeable wear after multiple soldering.

Illustration of Electrolysis During Soldering

Wear of the thermode by the elctrolysis process at thermodes voltages above 1.5 volts.


Other manufacturers therfore allow a film to run between the thermode and the solder joint, which unfortunately also lenghens the soldering time due to simultaneous thermal insulation.


This electrolysis can not occur with our technology because our voltage at the thermode is much lower and we also work at a high frequency.


In addition to this electrolysis problem results in cable break in the thick copper leads of other systems.
