 Solding Parameters

1.Flux Station
A.Flux-Fry type GR8 
B.Applied by foaming 
C.Specific gravty-0.820 g/cm3
2. Conveyor Speed
A. 2.3 meters/min
3. Pre-heat Temperature
A. +85℃ measured on top surface of PCB
4. Solder
A.63/37 alloy
B. Dry wave-no oil
C.Approximate contact with wave-2 seconds
A. Fry GR8 is non-hygroscopic flux and does not require cleaning   
If cleaning is required on isolated areas such as finger connector,cold cleaning by hand with Alpua 564 is recommended,Care   must be taken to avoid solvent entering the keymodle. 


Mainly applied on computer keyboards,cash registers,industrial equipment and Man- Machine interfaces.
