Product code definition
Solder alloy composition is Sn62.6, Pb36.8, Ag0.4, Sb0.2
- Ensures outstanding continual printing with fine pitch (0.5mm/20mil) and even super fine pitch (0.4mm/16mil) applications at slow to fast (20-100mm/sec.) print speeds, and long stencil idle time.
- Carefully selected thixotropic materials ensure excellent slump resistance and significantly reduce the occurrence of bridging and solder beading.
- A small addition of antimony (Sb) reduces wetting tension and as a result, effectively reduces (tombstoning).
- Specially developed flux system, ensures both extremely high reliability and superior solder wetting.
- Extremely long stencil and tack time, offer a wide process window.
