Softwareupdate of Vapor Phase One V1.04

Anna Metzenroth

More flexibility in terms of temperature profiles and Galden©

Different types of Galden© are compatible now. The type of process medium, that is used determines the highest temperature that can be reached within the temperature profile and therefore also in the soldering process itself. To allow more flexibility in terms of temperature profiles and the solder medium we will now support more types of Galden©. Until now, process medium with a boiling temperature of 230°C was required. With the update, you can now use Galden© with a boiling temperature between 100°C and 250°C.  

Via “Boiling Temperature” the desired temperature can be set. The incorporated microprocessor will evaluate the given temperature profile and uses the boiling temperature for setting the heater. Meanwhile, the default setting for the boiling temperature remains set to 230°C.  

Further the anti-condensation temperature can now be selected manually. If no specific temperature is selected the “Anti-condensation” mode will be skipped and the lift will go straight up.  

More transparent soldering process

While the Vapor Phase One is on, you can now easily see in which status it is in. This makes the process much more transparent and understandable. Every second the current status is checked and disclosed to the user via the display. The status can be found under the new “i” (information) symbol.

The different statuses are:

  • Calibrating 
  • Idle 
  • Preheat 
  • Soldering 
  • Quick Cool

Improved control technology 

We continously improve our control technology. With the new update, a maximum temperature deviation of +-3 °C compared to the temperature profile is realized. The heating control is now switched off during the soldering process and only takes effect in the valley phase. This regulation caused high vibrations in the past. In order to enable faster cooling, the next but one profile stamp is compared with the actual temperature. The heating is switched off in the event of a high difference and only switched on again when the actual temperature has reached the target temperature.  The temperature is now controlled exclusively via the lift, which is following the target temperature using a PID-Controller, to reduce Oscillation. In the following graphic this is illustrated: The red line is the temperature that should be reached at the time. The blue line shows the actual temperature using the previous software version.  The green line shows the actual temperature that is reached in the process after the latest software-update.

We will keep you updated about our process of learning and improving the Vapor Phase One in cooperation with our customers and own experiences. Stay tuned!
