Hand soldering leads to risk of damage. If performed use
tweezers to hold both capacitors terminals followed by
weldingꢀprocedure.ꢀAvoidꢀexcessiveꢀforceꢀandꢀtouchingꢀ
capacitor body while soldering. Once the capacitor is
removed from the board should not be weld again.

package body surface that is facing up during assembly reflow.
