▶Limit Pressure on Capacitor Installation with Mounter
A capacitor that has been damaged should be discarded to avoid later problems resulting from
mechanical stress.
Pressure must not exceed 4.9 N with a tool end diameter of 1.5mm when applied to the
capacitors using an absorber, centering tweezers, or the like. An excessively low absorber setting
position would result in not only the application of undue force to the capacitors but capacitor and
other component scattering,circuit board wiring breakage, and / or cracking as well, particularly
when the capacitors are mounted together with other chips having a height of 1 mm or less.
▶Flux
▷Select a flux that contains a minimum of chlorine and amine.
▷After flux use, the chlorine and amine in the flux remain and must therefore be removed.
