during 2±1s in the molten solder with a
temperature of 235±5°C.Pick up the
capacitors-and cleaned with solvent, and put in
on the> 10 times microscope.
After soldering capacitor on the PCB, 1mm of
bending shall be applied for 1 second as shown
by Drawing.
Apply 2.5 x rating voltages to both Terminations
for 5 seconds. Charge and discharge current
are less than 50mA.
