What is SMT? I believe that everyone in the electronics industry is no stranger. Let's explain it to you by Xiaobian: SMT is a surface mount technology (short for Surface Mounted Technology) and is the most popular technology in the electronics assembly industry. And crafts.

Its main features are as follows: high density of SMT assembly, small size and light weight of electronic products, and the size and weight of patch components are only about 1/10 of that of traditional plug-in components. After SMT is generally used, the volume of electronic products is reduced by 40%~60. %, weight loss 60% ~ 80%. High reliability and strong seismic resistance. The solder joint defect rate is low.

It is because of its high frequency characteristics that it greatly reduces electromagnetic and radio frequency interference.

Easy to automate and increase productivity. Reduce costs by 30% to 50%. Save materials, energy, equipment, manpower, time, etc.

Surface mount technology (SMT) is an electronic assembly technology that originated in the 1980s and installed electronic components such as resistors, capacitors, transistors, integrated circuits, etc. on printed circuit boards. And electrical bonding is formed by brazing. The biggest difference from the plug-in package is that the surface mount technology does not require a corresponding through hole for the component pins, and the surface mount technology has a much smaller component size than the plug-in package. COG (Chip-On-Glass) is a bare-chip (Bare chip) connected directly to the glass of the LCD by wire bonding and sticking. The current COG bonding technology is a driver IC with gold bumps. The bare chip is connected directly to the LCD panel using ACF. After listening to the narrative of Xiaobian, I believe that everyone has a clearer understanding and make better choices in the electronic assembly industry.
