NP505-LT is a no-clean, Pb-free, zero-halogen solder paste for assemblies that have temperature sensitive substrates and components. Warping is becoming more evident with the trend towards complex boards and the trend of using thinner and larger packages and boards. The defects caused by the warpage may decrease board reliability and increase in rework. NP505-LT is designed to reduce warpage inherent to board-to-package. NP505-LT is classified ROL0.

Performance Characteristics:
• Classified ROL0 per IPC J-STD-004B
• Zero-Halogen (none intentionally added)
• Low reflow peak temperatures (175-215°C)
• Reduced reflow temperatures improving efficiency in energy and cost
• Reduction in board-to-package warpage
• Low voiding potential under QFNs (< 15%)
• Wide reflow profile window with good solderability on various PCB surface finish
• Excellent activity and printability
• Extremely stable paste properties
• Colorless residues for easy post-reflow inspection
