MINIATURE ALUMINUM ELECTROLYTIC CAPACITORS
Reflow soldering method for series of VM, VL
1. Recommended conditions for reflow soldering
The aluminum electrolytic capacitor is subjected to soldering by reflow method.
Temperature and time conditions of reflow soldering shall be set as per each temperature profile shown below
as a standard. The following are recommended conditions in the case of reflow soldering method for the
aluminum electrolytic capacitor.
(1) The capacitor shall not be subjected to either flow or dip soldering method.
(2) Avoid soldering twice by reflow. The number of reflow time for aluminum electrolytic capacitor shall be once
basically. If this type of capacitor has to be inevitably subjected to the reflow twice, enough cooling time between
the first and the second reflow (at least more than 30 minutes) shall be taken to avoid the consecutive reflows
by all means.
(3) On setting the reflow conditions, it shall be done lest the temperature at surface of the capacitor should exceed
more than 175 C
