Process
SOLDERING: Depending on the application, this component is
suited to the following methods:
- Terminals being Tin/Lead plated over a nickel barrier, the use of
slightly activated flux is suitable.
- Soldering on double wave machine. The bath temperature is
generally 225˚C±5˚C and soldering time < 5 sec.
- Cleaning according to typical washing processes.
- Infrared Reflow Soldering in accordance with CECC00802
Packaging
