Soldering gun procedure
Do not exceed
Note the follows, in case of using solder gun for replacement.
1)The tip temperature must be less than 280 for the period within 3
seconds by using soldering gun under 30W
2) The soldering gun tip shall not touch this product directly.
Soldering volume
Note that excess of soldering volume will easily get crack the body of
this product.
