Technologies and emissions
Soldering processes are also classified based on the liq-
uidus temperature of the solder and are used in different
applications:
HIGH TEMPERATURE
SOFT SOLDERING HARD SOLDERING SOLDERING
Liquidus temperature < 450 °C/842 °F > 450 °C/842 °F > 900 °C/1,652 °F
Materials • Copper and copper alloys • Steel • Stainless steel
• Sheet steel • Brass • Nickel
• Aluminum • Copper • Cobalt
• Zinc • Silver (alloys) • Ceramics
• Stainless steel • Gold (alloys)
Application examples • Electronics manufacturing • Instrument making • Electronics manufacturing
• Electrical installation • Plumbing installation • Jewelry making
• Sanitary engineering • Goldsmith work • Heating and air conditioning
• Jewelry and handicrafts • Tool making technology
• Heating construction • High frequency technology • Turbine production
Use of flux X X —
Depending on the specific application and SOLDERING FUME CAUSES
requirements, solder alloys (solder wire, solder THREE TYPES OF DAMAGE
bars, solder paste) and halogen-free fluxes
(mainly containing rosin) are used for both
soft and hard soldering. During the soldering
process, a significant portion of the flux and a
small amount of the solder vaporize.
This creates aldehydes, gases, and aerosols, HUMAN MACHINE PRODUCT
among other things, which have been proven
to be harmful to health. These substances
also negatively impact manufacturing equip-
ment and products.
