Soldering: Capacitors can be attached by

conventional soldering techniques - vapor phase,

infrared reflow, wave soldering and hot plate

methods. The Soldering Profile charts show

recommended time/temperature conditions for

soldering. Attachment with a soldering iron is not

recommended due to the difficulty of controlling

temperature and time at temperature. If hand

soldering is necesary, the soldering iron must never

come in contact with the capacitor.

solder joints. The dimensional configurations shown

are the recommended pad geometries for both wave

are intended to be a starting point for circuit board

designers and may be fine tuned if necessary based

upon the peculiarities of the soldering process and/or

circuit board design.
