What is SMT? I believe that everyone in the electronics industry must be familiar with it. Let me explain to you below: SMT is Surface Mount Technology (Surface Mounted Technology) (abbreviation for Surface Mounted Technology), and it is the most popular technology in the electronics assembly industry. and craft.

Its main features are as follows: SMT assembly density is high, electronic products are small in size and light in weight, and the volume and weight of patch components are only about 1/10 of traditional plug-in components. Generally, after using SMT, the volume of electronic products is reduced by 40%~60 %, the weight is reduced by 60%~80%. High reliability and strong earthquake resistance. Solder joint defect rate is low.

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

Easy to automate and improve production efficiency. Reduce costs by 30% to 50%. Save material, energy, equipment, manpower, time, etc.

Surface mount technology (SMT, surface mount technology) is an electronic assembly technology that originated in the 1980s. It is to mount electronic components, such as resistors, capacitors, transistors, integrated circuits, etc., on printed circuit boards. And form an electrical connection by brazing. The biggest difference from the plug-in package is that the surface mount technology does not need to reserve corresponding through holes for the pins of the components, and the component size of the surface mount technology will be much smaller than that of the plug-in package. COG (Chip-On-Glass) is to directly connect the bare chip (Bare chip) on the glass of the LCD by using wire bonding and glue. The current COG bonding technology is to use the driver IC with gold bumps Bare chips, use ACF to connect directly to the LCD panel. After listening to the editor's narration, I believe that everyone will have a clearer understanding and make better choices in the electronic assembly industry.
