Process  
SOLDERING: Depending on the application, this component is  
suited to the following methods:  
Terminals being silver or gold plated over a nickel barrier, the  
use of slightly activated flux is suitable.  
– Soldering on double wave machine for vertical versions:  
soldering time < 5 sec.  
– Cleaning according to typical washing processes.  
– Infrared Reflow Soldering in accordance with IEC 61760-1.
