2. Conveyor Speed
A. 2.3 meters/min.
3. Pre-heat Temperature
A. +88°C measured on top surface of PCB
4. Solder
A. 63/37 alloy
B. Dry wave – no oil
C. Approximate contact with wave – 2 seconds
5. Cleaning
A. Fry GR8 is non-hygroscopic flux and does not require
cleaning
B. If cleaning is required on isolated areas such as finger
connector, cold cleaning by hand with Alpha 564 is
recommended. Care must be taken to avoid solvent
entering the keymodule.
