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.
