Precaution for soldering
Note that this product will be easily damaged by rapid heating, rapid
cooling or local heating.
Do not give heat shock over 100°C in the process of soldering. We
recommend to take preheating and gradual cooling
Soldering gun procedure
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.
