Metal packaging is an electronic packaging form that uses metal as a shell or base, the chip is installed directly or through the substrate on the shell or base, and the leads pass through the metal shell or base mostly adopt glass-metal sealing technology; metal shells and tubes for packaging are one of the important components of the metal packaging process. The functions of metal tube shells for packaging are: ① Mechanical support: the bearing circuit protects it from mechanical damage and provides physical protection; ② Electrical signal: the lead wire plays an internal and external electrical connection, and participates in the transmission of telecommunications between the internal circuit and the peripheral circuit; ③ Heat dissipation: For power circuits, an important function of the metal tube shell is to transfer the heat generated by the circuit to the outside world to avoid thermal failure of the circuit; ④ Shielding: Electromagnetic shielding metal tube shells 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-sealed packaging formed by the shell and the cover plate, protecting the circuit from the influence of harsh climates in the outside world, especially the corrosion of the circuit by water and gas.
