What is tantalum capacitor, and what are the differences between tantalum capacitor and electrolytic capacitor? 2

3、 Manufacturing process of tantalum capacitors

The manufacturing process of tantalum capacitors mainly includes the following steps:

1. Preparation of Tantalum Metal Sheet diode

Tantalum metal sheet is the electrode of tantalum capacitor, which requires high-purity tantalum metal as raw material and processed through multiple processes. Firstly, the tantalum metal sheet is processed into the desired shape and size, and then surface treated to improve its surface roughness and surface area, making it easier to bond with tantalum oxide thin films.

2. Anodizing

Anodizing is a crucial step in the preparation of tantalum oxide thin films. Firstly, the tantalum metal sheet should be used as the anode, and a voltage should be applied in the electrolyte to form an extremely fine tantalum oxide film on its surface. This tantalum oxide film has the characteristics of high density, high stability, and low leakage current.diode

3. Assembly of capacitors

Assemble tantalum metal sheets and tantalum oxide thin films together to form a capacitor. This process requires aligning the tantalum metal sheet and tantalum oxide film, and adding an appropriate amount of conductive adhesive between them to ensure their electrical performance.diode

4. Encapsulation

Place the capacitor in a plastic or metal casing to protect it from external environmental influences. This process requires the use of specialized packaging equipment to ensure the packaging quality and reliability of capacitors.diode
