Type-4 No-Clean Low Voiding Leaded Sn63/Pb37 Solder Paste
- Employment of rigidly classified 20-38 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.
- Carefully selected flux chemistry ensures low voids formation.
- Extremely long stencil idle time and tack time offers a wide process window
- Low color flux residue offers superior cosmetic appearance.
- Conforms to Bellcore tests (Copper Mirror, Halides, Surface Insulation Resistance, Electro migration) GR-78-CORE, Issue 1.
- Uses carefully classified solder powder with uniform particle size.
- Superior workability, solderability and electrical reliability.
- Applicable for super fine pitch SMT production.
