1.Different in activator.The activator has a great influence on the using effect,the weaker the better.
2.Different in main material.The grade of rosin in the soldering flux is different.868 and 625 are made in rosin which are in different grades.
R-868-LO
1.Weak activity,spaceflight military standard,high boiling point, unleaded, and no-clean soldering flux.
2.This soldering flux is high conductivity,no-clean and no corrosion to the items,which is special for repairing BGA,IC module,military products and advanced digital products(Apple series).
RMA-625-LO
1.Semi-active, military standard,high boiling point, unleaded, and no-clean soldering flux.
2.This soldering flux is high conductivity,no-clean and no damage and corrosion to the items,which applies to repair cell phone,precise instrument and digital products.
RMA-625A
1.Medium activity,unleaded,no-clean soldering flux.
2.This soldering flux is high conductivity,no-clean and no damage and corrosion to the items,which applies to repair cell phone and digital products.
RMA-223
RMA-223 is medium activity rosin soldering flux,which is widely used in phone SMD repairing.
