M-T20 solder paste M-T20 is designed for electronic circuit board surface mount technology and design without adding halogen-free cleaning paste. The flux of good printing performance, a high resistance to dry capability, spot light, full, at a reflux temperature can board a small amount of clear and transparent welding volatile residue. The residue is not easy to absorb moisture stable non-corrosive, so no cleaning greatly reduce production costs, but also cleared the use of cleaning agents may bring adverse environmental impacts. Note: 1. Solder metal powder and an organic solvent, try to be careful, to avoid contact with skin, if attached to the skin and clothing, as soon as possible with the alcoholic solvent to erase paste. 2. Reflow equipment, install an exhaust pipe and weld zone, do not inhale vapors emitted during reflow. 3. Please use appropriate gloves when operating, to wash their hands before meals and after welding work. 4. Save paste in the refrigerator (0 ℃ -10 ℃), preferably 5 ℃ -10 ℃. 5. When the paste is removed from the refrigerator, should be placed at room temperature for more than three hours until the reply. 6. Remove the container from the required amount of solder paste, once used, not back into the original container should be placed separately saved. 7. After long-term transportation paste may have a slight dissociation, it is recommended before use Stir by hand stirring for about 10 minutes, the automatic mixer for about 5 minutes. 8. Use the appropriate temperature solder paste is about 23 ℃ -25 ℃, humidity below 60. 9. Printing: Printing speed is recommended for 12-55 mm / s, squeegee pressure of 30n / mm, running 60-65 degree angle, welding soon as possible after printing.
