Aluminum Organic Capacitor (AO-CAP)

A720 Polymer Aluminum

Soldering Process

The KEMET families of surface mount capacitors are

compatible with wave (single or dual), convection, IR,

orvaporphasereflowtechniques.Preheatingofthese

components is recommended to avoid extreme thermal

stress.KEMET'srecommendedprofileconditionsfor

IPC/J-STD-020D standard for moisture sensitivity testing.

passes at these conditions.

Notes:

Hand soldering leads to risk of damage. If performed use

tweezers to hold both capacitors terminals followed by

welding procedure. Avoid excessive force and touching

capacitor body while soldering. Once the capacitor is

removed from the board should not be weld again.
