Applications
1. High-temperature lead-free vapor phase soldering
Galden HS 260 is used as the process fluid in VPS equipment for soldering electronic components and semiconductor packages onto printed circuit boards. It represents the highest-temperature grade in the Galden LS/HS range and is intended for processes requiring temperatures approaching 260°C.
2. Reflow of complex or high-thermal-mass PCB assemblies
The condensation-based heating mechanism can provide uniform heat transfer around components with different sizes, geometries and thermal masses. HS 260 may therefore be suitable for:
- Thick or multilayer printed circuit boards
- Power electronics assemblies
- Large connectors, transformers and inductors
- Assemblies containing substantial copper areas
- High-density electronic modules
This application suitability is an engineering inference from the uniform condensation-heating principle used in VPS.
3. Specialized solder alloys and high-temperature reflow profiles
HS 260 can support lead-free or specialized soldering processes whose validated profile requires a higher vapor temperature than Galden LS 230 or HS 240 can provide. The grade must still be selected according to the solder-paste specification and the maximum temperature ratings of the PCB, components, connectors and polymeric materials.
FAQ
1. What is Galden® HS 260 primarily used for?
It is primarily used as the working fluid in vapor phase soldering equipment for mounting electronic components and semiconductor devices onto printed circuit boards. The process uses the latent heat released when Galden vapor condenses on the cooler assembly.
2. How does Galden® HS 260 help prevent overheating?
The maximum heating temperature is controlled by the fluid’s vapor temperature. Once the assembly reaches the vapor temperature, condensation decreases significantly, providing a natural thermal limit and helping protect PCBs and components from uncontrolled overheating.
3. Is Galden® HS 260 suitable for lead-free soldering?
Yes. Syensqo positions Galden® LS/HS fluids as lead-free VPS solutions capable of supporting processing temperatures up to 260°C. The LS/HS product family is also described as RoHS compliant.
4. What types of assemblies may benefit from Galden® HS 260?
It may be appropriate for validated VPS profiles involving high-thermal-mass or complex assemblies, such as multilayer PCBs, power-electronics modules, large connectors, transformers and boards with substantial copper content. Suitability must be confirmed against the solder-paste specification and the temperature ratings of every component and substrate.
5. What is the shelf life of Galden® HS 260?
Syensqo states that Galden PFPE fluids remain chemically stable for more than 20 years when stored in their original sealed containers. Actual storage requirements should follow the current product safety data sheet and local handling regulations.
