Kester R562 Solder Paste for Extreme Environments
Kester R562 Solder Paste is a high-performance organic acid, water-soluble formulation specifically engineered to withstand severe environmental exposure during printed circuit board assembly. Developed by Kester, this specialized material overcomes traditional stability limitations, delivering consistent print quality and reliable solderability under fluctuating shop-floor conditions.
Key Advantages of R562 Solder Paste
Standard water-soluble pastes frequently suffer from slump or rapid drying when ambient moisture levels shift. Choosing this advanced formulation offers critical process benefits:
- Superior resistance to environmental extremes, preventing premature drying in low relative humidity.
- Excellent slump resistance in high relative humidity environments to reduce bridging risks.
- Long-lasting tack retention for stable component placement over extended open times.
- Robust organic acid chemistry providing exceptional flux activity for defect-free joints.
- Easy post-reflow residue removal using standard water cleaning systems.
