Characteristics Of Main Products
SS48-M955LV Low voiding type. Reduces voiding regardless of component type, such as BGA and PwTr
| Code | 48 | 58 |
| Particle size (µm) | 20 – 45 | 20 – 38 |
Solder alloy composition is Sn 36Pb 2
- Employment of rigidly classified 2038 micron solder powder ensures outstanding continual printing with fine pitch (0.5mm/20mil) and even super fine pitch (0.4mm/16mil) application and long stencil idle time.
- Conforms to Bellcore tests (Copper Mirror, Halides, Surface Insulation Resistance, Electro migration) GR-78-CORE, Issue 1.
- Extremely long stencil idle time and tack time offers a wide process window
- Carefully selected flux chemistry ensures low voids formation.
- Low color flux residue offers superior cosmetic appearance.
