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.
