·      PROCESSING

   Switch Operation and Taping

1)   Use tweezers or ballpoint pen for operation. 

2)   Flux cleaning should be done with removing the tape.

3)   If the tape was removed, the adhered may less than before. Also it is possibly causing flux inflow.

 

4)   Sealed switches can be immersed into aqueous, and using detergent and isopropyl alcohol to wash.

 

 

§  SOLDERING

·      Reflow soldering (see the figure below)

1) Applying reflow soldering only once (Device: In-line or Batch system).

 

2)   When soldering two or more terminals in the common land, it should be soldered them respectively.
