Electronic packaging can be broadly classified into two types: plastic packaging and metal packaging. Plastic packaging is commonly used in low-power electronic devices such as smartphones, tablets, and other consumer electronics. Metal packaging, on the other hand, is used in high-power electronic devices such as power modules, automotive electronics, and industrial automation systems.
Plastic packaging is cost-effective, lightweight, and easy to manufacture. It is made of thermoplastics such as polycarbonate, polyethylene, and polypropylene. Plastic packaging can be molded into complex shapes and is suitable for high-volume production. However, plastic packaging has limitations in terms of mechanical strength, heat dissipation, and EMI shielding.
Metal packaging, on the other hand, offers superior mechanical strength, thermal conductivity, and EMI shielding. It is made of metals such as aluminum, copper, and stainless steel. Metal packaging is suitable for high-power electronic devices that generate a lot of heat. It can be customized to meet specific requirements and is suitable for low-volume production. However, metal packaging is more expensive than plastic packaging and is more difficult to manufacture.
