September 3, 2026 ALPHA JP-501 Solder Paste
ALPHA JP-501 is a low-temperature, lead-free, no-clean solder paste engineered specifically for precision jet printers. Manufactured by industry leader MacDermid Alpha, this zero-halogen formulation supports low-thermal-stress assembly on sensitive electronic substrates.
Performance Characteristics of ALPHA JP-501
Featuring a low-temperature alloy with a melting point of 138°C, the paste operates successfully across peak reflow profiles between 155°C and 190°C. Rated ROL0 per IPC J-STD-004, it leaves a clear, colorless flux residue that ensures high electrical reliability.
- Formulated for seamless application in high-speed jet printing equipment.
- Low melting point alloy (138°C) to protect heat-sensitive components.
- Zero-halogen flux system delivering excellent electrical reliability.
- Broad reflow process window across traditional circuit board surface finishes.
Assembly Guidelines and Compatibility
When applying ALPHA JP-501 in production, all interactive components must be lead-free. This avoids forming tin/lead/bismuth intermetallics, which melt below 100°C and compromise joint stability.
