Electronic packaging refers to the packaging of circuit chips to protect them from the external environment.

Electronic packaging materials refer to the matrix materials used to carry electronic components and their interconnection, and play the roles of mechanical support, sealing, environmental protection, signal transmission, heat dissipation and shielding.

At present With the development of integrated circuits, the most used packaging material is carrier tape

Electronic packaging materials include substrate, wiring, frame, interlayer medium and sealing material. As an electronic component, electronic packaging substrate material mainly provides mechanical bearing support, air tightness protection and heat dissipation of electrical equipment for electronic components and their interconnection.

① Substrate: high density multilayer packaging substrate mainly plays the role of electrical transition between semiconductor chip and conventional PCB (printed circuit board), and provides protection, support and heat dissipation for the chip. The main materials include ceramics, epoxy glass, diamond, metal and metal matrix composites.

② Wiring: conductor wiring is completed by the metallization process. Substrate metallization is to install the chip on the substrate and connect the chip with other components.

③ Interlayer dielectric: dielectric materials play a very important role in electronic packaging, including protecting circuits, isolating insulation and preventing signal distortion.

④ Sealing materials: the sealing materials of electronic devices and integrated circuits are mainly ceramics and plastics. The earliest materials used for packaging were ceramics and metals. With the gradual improvement of circuit density and function of electronic products, the requirements for packaging technology are becoming higher and higher, which has changed from metal / ceramic packaging to plastic packaging(carrier tape). Nowadays, epoxy resin sealing materials account for about 90% of the density materials of the whole circuit substrate.#carrier tape #embossed carrier tape
