Note:

For best result, please use a hot air gun and rotate the connector to evenly apply heat.
Please raise the temperature from low to high gradually when you use the hot air gun to heat the wire connector.
Please DO NOT set the high temperature at the beginning, or the surface of connector will be over-heated, which will lead to the tube melt while the solder ring still not melt.
Keep the hot air gun at the proper distance. Don't get too close.
