Heat transfer agent for your vapor phase soldering technology

Fluid (Galden®)

As Galden is the name given to a perfluorinated liquid (perfluoropolyether, PFPE) that is used in the Vapor phase soldering technology is used. Galden is characterized by an exactly definable boiling point, which allows extremely precise temperature control. This enables the assemblies to be heated evenly without overheating or the influence of oxygen. This property makes Galden particularly suitable for complex or sensitive soldering applications.

Efficient heat transfer through condensation

Galden is heated in the soldering system until it vaporizes and produces a homogeneous vapour. This vapor condenses on the cooler surfaces of the electronic assembly and transfers the heat very efficiently.

Special advantage

Da die Dampftemperatur durch den Siedepunkt begrenzt ist, wird ein Überhitzen empfindlicher Komponenten effektiv verhindert, ein zentraler Vorteil beim:

  • temperature-sensitive soldering
  • lead-free soldering with higher temperature requirements

Closed loop - safe and sustainable

The condensed Galden vapor flows back into the liquid container and is vaporized again. This results in a closed cycle. Due to its chemical inertness, non-flammability and reusability, Galden is particularly suitable for industrial soldering processes. Galden also ensures uniform, gentle and reproducible heat transfer.

IBL recommends the Galden heat transfer agent from SYENSQO for use in vapor phase soldering systems. The LS and HS series were developed in collaboration with SYENSQO to meet the requirements of vapor phase soldering:

  • Highest thermal stability
  • Consistent quality even over long periods of use

Galden is characterized by the following added values:

  • High thermal stability: Ideal for controlled heat transfer
  • Chemical inertness: Does not react with other substances
  • Low viscosity: enables efficient heat transfer
  • Non-flammable & non-toxic: Safe for industrial use
  • Defined boiling points: for precise temperature control during soldering
