There are four main types of materials for electronic packaging to support, metal, glass, ceramic, optoelectronic materials. Metal packaging is a packaging technology that uses metal as the housing material, and the wire passes through the metal shell. Most other materials are also used. As the name implies, these materials play a great role in achieving electronic chip installation, support, and environmental protection. Compared with other materials of the same type, they have better thermal conductivity, conductive heat dissipation, and the ability to shield the outside world.
The vast majority of packaging uses plastic packaging, the raw material is mainly resin, and other metal leads and metal pins are also used. High-quality packaging such as ceramic packaging, the raw material is mainly ceramics, including substrates and tubes, and there are also metal leads and Filler.
The packaging of semiconductor electronic components not only serves to connect the bonding points of the internal integrated circuit chip and the external electrical components, but also provides a stable and reliable working environment for the integrated circuit, and plays a mechanical or environmental protection role for the integrated circuit chip. Integrated circuit packaging should have strong mechanical properties, good electrical performance, heat dissipation performance and chemical stability. The quality of the packaging is closely related to the overall performance of the integrated circuit.
Different types of integrated circuits have different application occasions and air tightness requirements, and their processing methods and packaging materials are also different. In the early days of integrated circuits, the packaging materials used a mixture of organic resin and wax, which was sealed by filling or injecting. Reliability is poor; rubber has also been used for sealing, but its heat resistance, pressure resistance and electrical performance are not good, and it has now been eliminated. At present, the popular hermetic packaging materials are ceramic-metal, glass metal and low-melting glass-ceramics. Due to the demand for mass production and cost reduction, many integrated circuits currently use plastic packaging materials, which mainly use thermosetting resins. The mold is heated and pressurized to complete the packaging, and its reliability depends on the characteristics and molding conditions of the organic resin and additives. Plastic packaging materials are non-airtight packaging materials, which have poor heat resistance and hygroscopicity.
There are many forms of electronic packaging, one of which is a surface mount type. This packaging form has a feature of ball contact display. In order to replace the pins, a lot of thick rivet points are manufactured in an array manner, and an electronic chip is mounted on the surface of the substrate. Then it is hermetically sealed. It is also a packaging form commonly used in electronic products that require a lot of pins. Mainly used in several places, such as mobile phones, mobile phone equipment. In the future, it may be mostly used for computers. The other mode is glass-sealed electronic packaging. It has a window, and the heat dissipation performance is much more than the plastic material above. It can still be unaffected in harsh conditions.
Electronic packaging, also known as electronic sintering, is a protective cover for electronic chips, which has the ability to install and protect electronic products from the external environment. The quality of electronic packaging products depends on whether the sintered product process is beautiful, which is also a direct judgment of the product The basics of good and bad. Electronic packaging products have a great effect on electronic equipment. If there is something wrong with the packaging shell, it will inevitably affect the main electronic chips and cause damage to the entire set of equipment. Therefore, an electronic packaging and testing industry is derived accordingly.
Obviously it is chip manufacturing, such as the information industry. Mobile phones, computer hardware, smart air conditioners, smart home appliances, routers, microcontrollers, and other digital circuit related products all need to use semiconductors. It can be said that people are living with semiconductors everywhere in people’s lives.
