Lead Free Solder Pastes
Available Alloys: SnAgCu, SnAg, SnAgBi, SnAgBiCu - Please see below for more details
Alloy: SnAgCu
No Clean
F 640
F 640 Solder Paste series is a state-of-the-art lead free no clean solder paste that promotes wetting and minimises soldering defects.
The F 640 Series exhibits minimal slump and has excellent print-after-wait performance.This formula provides superior performance on a variety of surface finishes and leaves behind a clear residue. Reflow can be accomplished in air or nitrogen.
Key Benefits of F 640:
- exceptional print to print consistency
- excellent wetting
- min. 8 hour tack and work life
- very good print after wait performance
- SIR 85/85 > 10E10 Ohm
- constant performance at 30°C for 7days
- work conditions between 20 and 32°C
- Fulfils Siemens Standard accord. DIN EN 29454 Part 1
- Passes J-STD-004
