Galden vapor phase consumable

Choose the right heat transfer fluid for your electronic soldering process

Vapor phase soldering technology is based on the condensation of the heat transfer fluid, ensuring uniform, precise and controlled heat transfer to the PCBa. The choice of the heat transfer fluid (Galden) determines the boiling point, the vapor temperature, and consequently the maximum process temperature. We supply Galden in LS (Low Soldering) and HS (High Soldering) grades:

LS200 (200°C)

LS215 (215°C)

LS230 (230°C)

HS235 (235°C)

HS240 (240°C)

HS260 (260°C)

Supplied in 5 kg containers (equivalent to approximately 2.747 L of Galden)

What are the key advantages of Galden ?

Controlled temperature point

In vapor phase soldering, precise temperature control is essential to ensure uniform and defect-free reflow, especially for assemblies with complex geometries or high component density.

he condensation of Galden vapor allows perfectly uniform temperatures up to 260 °C, preventing cold joints or overheating that could damage the integrity of SMD components.

Unlike other fluids, Galden retains its properties even after many cycles, making it a reliable and durable consumable for vapor phase reflow processes.

Chemical stability and total inertness

Thanks to its perfluorinated molecular structure, Galden exhibits exceptional chemical inertness, making it fully compatible with most industrial materials, including sensitive metals, plastics and composites. It does not decompose, form residues, or react with system components, thereby extending equipment lifespan.

Enhanced safety: non-flammable, non-explosive

Galden has no flash point and no risk of self-ignition, making it extremely safe to handle, even in high-temperature environments. It produces no explosive vapors, and in the event of a thermal incident, its decomposition gases remain manageable with proper ventilation systems.

Finally, it creates an inert atmosphere without the need for nitrogen, preventing oxidation during soldering and ensuring clean, residue-free solder joints without defects related to ambient conditions.

What is the environmental impact of Galden?

Galden has a well-controlled environmental profile: it is non-toxic, non-flammable, non-polluting, and exhibits very low solubility in water. Although it is not biodegradable, its high chemical stability allows it to be recovered, filtered, and effectively reused in industrial environments. Compliant with the RoHS directive, it contains neither lead nor toxic halogens. However, at the end of its life, it must be disposed of through specialised channels to comply with environmental regulations.

Can a single grade of heat transfer fluid be used for several types of alloys?

Yes, provided that the boiling point of the selected heat transfer fluid is always higher than the reflow temperature of the alloy.

For example, with HS240, used in an IBL Premium range machine, both processes can be carried out successively: SnPb (210°C / 215°C max) and lead-free (SnAg and/or SnAgCu = 240°C max).
