Disadvantages of traditional conductive adhesives

1, SMT is the abbreviation of English "Surface mount technology", that is, surface mount technology, which is a more traditional installation method. Its advantage is high reliability, but its disadvantage is large volume and high cost, which limits the miniaturization of LCM.

2.COB is the abbreviation of "Chip On Board" in English, that is, the chip is bonded on PCB, which can save PCB and other materials, greatly reduce the volume and reduce the cost from the price. As IC manufacturers are reducing the output of QFP (a kind of QFP(SMT) package in LCD control and related chip production, the traditional SMT method will be gradually replaced in future products.

3.TAB is the abbreviation of English "Tape Aotomated Bonding", that is, anisotropic conductive adhesive connection mode. TCP IC is fixed on LCD and PCB with anisotropic conductive adhesive. This installation method can reduce the weight and volume of LCM, and the installation is convenient and reliable! ?

4.COG is the abbreviation of "Chip On Glass", that is, the chip is directly bonded to the glass. This installation method can greatly reduce the volume of the whole LCD module and is easy for mass production. It is suitable for LCD used in consumer electronic products, such as mobile phones, PDA and other portable electronic products. Driven by IC manufacturers, this installation mode will be the main connection mode between IC and LCD in the future. ?

5.COF is the abbreviation of "Chip on Film", that is, the chip is directly mounted on the flexible PCB. This connection mode is highly integrated, and peripheral components can be installed on flexible PCB together with IC.
