Production Processes

  • Winding
    Winding
    This is the process where conductive material, usually metal foil, is wound tightly to form the core of the capacitor. This winding is crucial for creating the capacitor's ability to store and release electrical energy.
  • Hot Pressing (Flat Core)
    Hot Pressing (Flat Core)
    Here, the wound core undergoes hot pressing to flatten it. This step is important for shaping the capacitor and can also influence its electrical characteristics.
  • Gold Spraying
    Gold Spraying
    Sputtering gold onto the capacitor components is likely a method of applying a very thin layer of gold. This layer can be important for improving conductivity and protecting against corrosion.
  • Heat Treatment
    Heat Treatment

    The components are subjected to heat treatment. This process can relieve stresses in the materials, improving durability, and ensuring the stability of the capacitor's electrical properties.

  • Core Testing (Energizing)
    Core Testing (Energizing)

    Testing the core, especially after energizing, is crucial. This step ensures the core to meet the necessary electrical specifications and is free from defects.

  • Welding
    Welding
    Welding is used to securely connect various components of the capacitor. This step must be performed with precision to ensure structural integrity and reliable electrical connections.
  • Potting
    Potting
    Potting involves encasing the capacitor in a protective material. This material protects the internal components from environmental factors and mechanical stress.
  • Final Product Testing
    Final Product Testing
    After assembly, the finished capacitor is rigorously tested. These tests confirm that the product meets all required specifications and performance standards.
  • Inspection
    Inspection
    A thorough inspection is conducted to ensure the quality of the finished product. This step is critical for maintaining high-quality standards.
  • Storage
    Storage

    Finally, the capacitors that pass all tests and inspections will be stored, which are ready for distribution or further processing.

Surge Buffering Capacitor SNUBBER Industry knowledge

What materials do surge snubber capacitor manufacturers use to make surge snubber capacitors? What are the advantages and limitations of these materials?

Surge snubber capacitors (also known as surge suppression capacitors or transient voltage suppression capacitors) are primarily used in circuits to protect equipment from overvoltage damage caused by lightning, power switching, or other transient events. When selecting materials for surge buffer capacitors, manufacturers consider a variety of factors, including the capacitor's electrical performance, physical characteristics, cost, and long-term stability.
material selection
Metal Oxide Varistors (MOVs): MOVs are a common material used in surge snubber capacitors. They are composed of zinc oxide (ZnO) and other metal oxides (such as cobalt, manganese, nickel, etc.). When an applied voltage exceeds the threshold of MOVs, they undergo a transition from a high-resistance state to a low-resistance state, allowing large currents to flow and suppressing voltage rise.
Polymer Matrix Composite Materials: In recent years, polymer matrix composite materials have also been used in surge buffer capacitors. These materials combine the high insulating properties of polymers with the conductivity of conductive particles such as carbon black, metal oxides, etc. When the voltage exceeds a certain threshold, the polymer between the conductive particles breaks down to form a conductive channel, thereby suppressing the voltage rise.
Ceramic Materials: Certain ceramic materials are also used in surge buffer capacitors. They have excellent thermal stability and electrical properties, but may cost more.
advantage
MOVs: MOVs have good nonlinear voltage-current characteristics and can provide effective surge protection over a wide voltage range. In addition, they have high energy absorption capacity and good thermal stability.
Polymer-based composite materials: These materials have lower capacitance and better high-frequency performance, making them suitable for high-speed data transmission and radio frequency applications. In addition, they offer high reliability and long service life.
Ceramic materials: Ceramic materials have excellent electrical properties and thermal stability, and are suitable for high temperature and high humidity environments.
limitation
MOVs: While MOVs have good surge protection properties, they can be affected by temperature, humidity, and mechanical stress. Additionally, their performance may gradually degrade after experiencing multiple surge events.
Polymer Matrix Composites: The properties of these materials can be affected by temperature and humidity. Their electrical properties may change in high temperature or high humidity environments.
Ceramic Materials: Ceramic materials are generally brittle and prone to cracking under mechanical stress. Additionally, their cost can be high, limiting their use in some low-cost applications.

How does the manufacturing process of the surge buffer capacitor factory ensure the stability and reliability of the capacitor?

In the early stages of the manufacturing process, detailed circuit design and component selection are required based on the specific application environment and needs of the capacitor. This includes selecting the appropriate capacitor type, dielectric, internal electrode materials, etc.
Pay particular attention to the fact that the capacitors should be able to withstand expected surge voltages and currents, as well as have good thermal stability and durability.
Material selection and control:
Choosing high-quality, stable-performance raw materials is the basis for ensuring the stability and reliability of capacitors.
The factory should establish a strict material inspection system and conduct strict quality control and screening of incoming materials.
Manufacturing process control:
During the manufacturing process, the process parameters of each production link, such as temperature, pressure, time, etc., should be strictly controlled to ensure the consistency and stability of the capacitor.
Especially for the key manufacturing steps of capacitors, such as dielectric coating, electrode manufacturing and assembly, advanced process technology and equipment should be used to ensure manufacturing accuracy and product quality.
Quality inspection and evaluation:
During the manufacturing process, a strict quality inspection system should be established to conduct multiple quality inspections on capacitors, such as appearance inspection, electrical performance testing, environmental adaptability testing, etc.
Capacitors that fail the test should be repaired or scrapped in time to ensure the quality of the factory capacitors.
Environmental suitability test:
Since capacitors may need to work under various complex environmental conditions, environmental adaptability tests should be conducted, such as temperature shock, damp heat, salt spray and other tests.
