STM is a surface assembly technology, and it is currently a popular art and craft in the electronic assembly industry. Electronic circuit surface assembly technology, also known as surface mount or surface mounting technology, is actually an assembly process that uses silver free corners or short lead surfaces to mount on the surface of printed circuit boards or other basic components. On the surface, the circuit technology is assembled by soldering or immersion welding.
1. High reliability and strong seismic resistance.
STM surface mount mainly uses chip like components with high reliability, and the components are small and light, so its seismic resistance is also very strong. Automated production of surface mount has high reliability. Generally, the defect solder joint rate is less than 10%, which is one level higher than the through hole component wave soldering technology, and can ensure the soldering of electronic products or components, reducing the disadvantages. Previously, about 90% of electronic products had adopted this technology.
2. Electronic products have a small volume and high assembly density
The volume of STM patch is only about 1/10 of traditional components, and its weight is only 10% of traditional components. Usually, it can reduce the volume of electronic products by 40% to 60%, and the weight can also be reduced by 60% to 80%. The area and weight occupied are greatly reduced. And it adopts through-hole installation technology, which can increase the density of installation components.
3. Good high-frequency characteristics and reliable performance
Due to the fact that the chip is a primitive component and is firmly attached, the device is usually without or with short leads, which directly reduces the influence of parasitic inductance and capacitance. This not only improves the high-frequency path of the circuit, but also reduces electromagnetic and radio frequency interference. The adopted design reaches three GHz, which can greatly shorten the transmission delay time. And the additional features reduce power consumption by 2-3 times.
There are so many advantages of STM patch, it's really hard to explain in a few words. Moreover, patch technology can also reduce costs and expenses.
