Energy and cost savings in electronics production
Easier than you think!
Electronics production without electricity – unthinkable! The largest consumers of electricity in SMT production are the reflow soldering systems. However, this soldering process is used in many electronics production facilities worldwide and is a very inefficient method of soldering in terms of energy. The extremely high power consumption of convection reflow systems is caused by the inefficient heat transfer via air.
A simple comparison
Heat transfer
30 - 120 W/(m²·K)
Connection power
60 - 90 kW
Average power consumption
15 - 22 kWh
Profile change
60 - 75 min
Product changes mean down time of the line
Excellent soldering quality needs nitrogen
Heat transfer
100 - 700 W/(m²·K)
Connection power
max. 25 kW
Average power consumption
max. 7 kWh
Profile change
max. 5 min
Changeover times are reduced to a minimum
Oxygen-free process eliminates need for nitrogen
Gentle soldering process without temperature peaks
Homogeneous heating with lowest Δt
Reduce energy consumption by up to 75 %
Energy costs will continue to rise and no one can accurately forecast how the trend will move in the long term.
Energy saving through vapor phase soldering!

Vapor phase soldering enables more than 20 times better heat transfer than air due to the liquid used! This means at the same time a saving of power consumption up to 70 % when using an ASSCON vapor phase soldering system. Find out more about the advantages of vapor phase soldering!
