LM Series Solder Reflow Recommendations
The LM Series capacitor is designed for use in
Infrared or Vapor Phase Convection solder reflow
processes. The chart at right indicates typical time-
temperature conditions for these processes.
Recognizing that a wide range of time and tem-
perature conditions is possible depending on each
manufacturer’s circumstances, it is recommended
that manufacturers adhere to the following general
process guideline:
MaxCap DLC peak temperature at the top sur-
face of the capacitor should be limited to 235°C for
less than 10 seconds.
Adherence to this guideline should enable suc-
cessful processing and allow for normal variation in
time and temperature for most customer processes.
