Applications
1. Vapor Phase Reflow Soldering (Main Application)
Galden LS 215 is primarily used as the heat transfer medium in vapor phase soldering systems. During operation, the fluid boils at 215°C, producing a saturated vapor that condenses on cooler printed circuit boards (PCBs). The released latent heat melts the solder paste uniformly without exceeding the fluid's boiling temperature.
Typical applications include:
- SMT PCB assembly
- Lead-free reflow soldering
- High-density electronic assemblies
- Prototype and low-to-medium volume production
2. Semiconductor Manufacturing
Galden LS 215 is used in semiconductor packaging processes where precise thermal control is required for assembling advanced electronic packages.
Typical applications include:
- BGA (Ball Grid Array)
- CSP (Chip Scale Package)
- QFN packages
- Flip-chip assembly
3. Automotive Electronics
Galden LS 215 is widely used for manufacturing automotive electronic control units (ECUs), power electronics, and ADAS modules where solder joint reliability is critical under vibration and thermal cycling.

FAQ
1. How long does Galden® LS 215 last?
Service life depends on equipment design, operating conditions, and maintenance practices. When used in a properly maintained vapor phase soldering system, Galden LS 215 typically offers a long operational life due to its excellent thermal and chemical stability.
2. How should Galden® LS 215 be stored?
Store Galden LS 215 in its original sealed container in a clean, dry environment away from contamination. Proper storage helps preserve the fluid's purity and performance.
3. Does Galden® LS 215 leave any residue after soldering?
Galden LS 215 evaporates cleanly during the vapor phase process and leaves virtually no residue on printed circuit boards, minimizing the need for post-process cleaning.
4.Can Galden® LS 215 be mixed with other heat transfer fluids?
Mixing Galden LS 215 with other fluids is not recommended. Using only the specified fluid helps maintain consistent boiling characteristics and ensures optimal soldering performance.
