Metal packageWhat are the characteristics of the shell and what is its structure? What are its development prospects and what are the requirements for development? The editor of Keweite will give you a detailed explanation below.

1. Development prospects, applications and requirements of metal shells

With the development needs of various electronic industries, metal packaging shells are widely used in military and civilian fields such as aerospace, aviation, navigation, field operations, radar, communications, and weapons. At present, products in the field of microelectronics are used more and more widely, and the demand is increasing, but the product quality requirements are becoming more and more stringent. The trend is towards ultra-miniaturization, multi-function, stability, light weight, high performance, and cost. The low-end development field; the power of the device increases, and the heat dissipation characteristics of the package housing have become a very important factor in choosing a suitable packaging technology.

Second, the structure and characteristics of the metal shell package

As one of the key components of integrated circuits, the case mainly plays the role of circuit support, electrical signal transmission, heat dissipation, sealing and chemical protection. The case occupies an important position in terms of the reliability of the circuit and the proportion of the circuit cost. To classify the material properties, the types of enclosures are: low temperature glass package, ceramic package and metal package. Ceramic packages and metal packages are considered to be fully sealed packages due to their material properties.

1. Mechanical support: The rigid shell carries the circuit to protect it from mechanical damage and provide physical protection.

2. Electrical signal: The lead wire on the transmission shell plays the role of internal and external electrical connection, and participates in the transmission of electrical signals between the internal circuit and the peripheral circuit.

3. Heat dissipation: For power circuits, an important function of the housing is to transfer the heat generated by the circuit to the outside world to avoid thermal failure of the circuit.

4. Shielding: The electromagnetic shielding metal shell can isolate electromagnetic signals to a certain extent and avoid electromagnetic interference.

5. Sealing protection: The internal circuit is isolated from the external environment through the air-tight installation formed by the shell and the cover plate, and the circuit is protected from the influence of the harsh external weather, especially the corrosion of the circuit by water.
