    Tips:  How to make a SMD Electrolytic Capacitor?

    1. Cutting of aluminum foil.
      This step is easy to understand. It is to cut a whole piece of aluminum foil into several small pieces to make it suitable for the needs of capacitor manufacturing.
    2. Riveting of lead wires.
      The pins outside the capacitor are not directly connected to the inside of the capacitor, but are connected to the inside of the capacitor through the inner lead. Therefore, in this step, we need to connect the inner leads of the anode and cathode with the outer leads of the capacitor by ultrasonic bonding. The outer lead is usually copper-plated iron wire or oxidized copper wire to reduce resistance, while the inner lead is directly connected with aluminum wire and aluminum foil. Everyone pays attention to these small steps, all of which require high precision machining.
    3. Winding of electrolytic paper.
      The electrolyte in the capacitor is not directly poured into the capacitor, and soaks the aluminum foil in a liquid state, but is attached to the aluminum foil layer by layer through the electrolytic paper that absorbs the electrolyte. Among them, the formula of the selected electrolytic paper is somewhat different from that of ordinary paper. It is microporous, and there should be no impurities on the surface of the paper, otherwise the composition and performance of the electrolyte will be affected. In this step, the electrolytic paper that does not adsorb the electrolyte is attached to the aluminum foil, and then rolled into the capacitor casing, so that the aluminum foil and the electrolytic paper form an interval similar to "101010".
