§  SOLDERING AND CLEANING PROCESS

Please ensure Switch in the ‘off’ position during the process of operation.

 

1)   Cleaning Process

Ultra-sonic cleaning probably stand out better effect.  Also, it should be controlled the temperature under 51°C if using steam cleaning.

 

2)   Hand Soldering

Using the soldering iron of 30 watts, meanwhile controlling the temperature at 320°C for roughly 2 seconds.

 

 

3)   Wave Soldering

Recommending the solder temperature at nearly 260°C for max. 5 seconds.

 

§  PACKAGE

Generally, Switches are shipped by standard IC tube.
