What Role Does Galden Play as a Heat Transfer Fluid in Vapour-Phase Soldering?
Galden is the primary heat transfer fluid used in vapour-phase soldering, as it determines heat transfer and temperature control throughout the entire process. Thanks to its precisely defined boiling point, it enables precise, uniform, and reliable heating of assemblies in modern electronics manufacturing.
Galden as a Heat Transfer Fluid in Soldering and Electronics Manufacturing
In modern soldering technology, choosing the right heat transfer fluid plays a crucial role. Galden has become the standard in vapour-phase soldering because it was specifically developed for applications with high thermal and chemical requirements.
Galden belongs to the group of perfluorinated polyethers (PFPE) and is characterized by its high stability and process reliability. These properties make it particularly well-suited for demanding processes in electronics manufacturing.
Boiling Point of Galden: The Foundation for Precise Temperature Control
Why is Galden's boiling point so important?
The key factor is the precisely defined and stable boiling point, which ranges from about 200 °C to 260 °C, depending on the variant.
This boiling point determines:
- the maximum process temperature
- uniform heat transfer
- adaptation to different soldering requirements
This makes Galden versatile enough to be used both for temperature-sensitive components and for applications involving lead-free solders.
Heat Transfer Through Galden in Vapour-Phase Soldering
How does Galden transfer heat in the vapour-phase soldering process?
As soon as Galden is heated within the system, it evaporates evenly and forms a dense vapour zone. When this vapour comes into contact with the cooler surface of the assembly, it condenses.
This process releases latent heat, which is transferred to the components with exceptional efficiency. This physical process ensures uniform heating of the entire assembly.
A key advantage is that heat distribution is independent of:
- component geometry
- size
- thermal mass
is carried out evenly.
Chemical Properties of Fluxes for Safe Soldering Processes
In addition to its thermal performance, Galden stands out for its chemical properties.
The fluid is:
- non-flammable
- non-conductive
- corrosion-free
- oxidation-resistant
Furthermore, it does not react with the components or materials in the assembly. This chemical inertness makes Galden ideal for use in sensitive electronic manufacturing processes.
Here you will find more information on the use of Galden as a heat transfer fluid for your vapour-phase soldering process.
Sustainability and Reusability of Galden
Another advantage of Galden is that it can be reused in the process.
During vapour-phase soldering, the condensed fluid can be recovered and returned to the cycle. Before it is fed back into the process chamber for another soldering cycle, it is purified through filters and thus prepared for reuse in the cycle. This reduces material consumption and improves cost-effectiveness.
The main advantages are:
- reusable
- residue-free evaporation
- stable process conditions over long periods of time
Why Flux Is Essential for Vapour-Phase Soldering
Why is Galden the ideal heat transfer fluid for vapour-phase soldering?
Galden combines precise temperature control, efficient heat transfer, and high chemical stability.
Thanks to its defined boiling point, reusability, and safe material properties, it is a key component of modern vapour-phase soldering systems. In electronics manufacturing, Galden plays a significant role in ensuring the quality, process reliability, and durability of solder joints.
