The manufacturing process flow for the Conductive Polymer Hybrid Aluminum Electrolytic Capacitors is as follows
1.Slit
The anode foil, cathode foil, and electrolyte paper are cut to the specified width from the source rolls of the specified length.
2.Lead Attachment
Leads for contacting the cathode and anode foil electrodes are attached either by crimping or by ultrasonic welding.
3.Coiling
The electrolytic paper is layered between the anode foil and the electrode foil. A coiled construction separates the electrodes. When the structure is coiled in this manner it is known as an "element."
4.Filling
The element is filled with the electrolyte(electrolytic solution + Polymer) using, for example, the vacuum method.
5.Assembly
The rubber plug is attached to the filled element. Then, the element is placed in the case.
6.Aging
The specified voltage is applied to grow an anode oxide thin film on the cut surface end and on any flaws in the formed oxide thin film.
7.Printing / Lead processing
Print the rated voltage, capacitance, polarity, etc. on the capacitor and process the lead to support SMD
8.Inspection
All units are subjected to functional testing and cosmetic inspection. Non-conforming units are removed from production.
