ODM/OEM FR-4 Double Sided PCB Assembly Electronic Circuit Board SMT& DIP PCBA Electronic PCB Assembly
SMT PCB Assembly Introduction
SMT is surface mount technology, which is a new generation of electronic assembly technology developed from hybrid integrated circuit technology. SMT PCB assembly refers to a circuit assembly technology that installs SMC/SMD (Chip Components) on the surface of a printed circuit board or other substrate, and sells and assembles it by reflow soldering or dip soldering.

SMT PCB Assembly Processing Technology requirements for PCB Design
In the process of SMT patch processing, all processing equipment has the characteristics of full automation, precision and speed. Then the PCB design must meet the requirements of SMT patch processing equipment in order to effectively guarantee product quality.
- PCB shape design
- PCB size design
- PCB thickness design
- PCB process side design
- PCB component layout design
- PCB Pad Design
SMT PCB Assembly Characterictics
1. High assembly density
Electronics are small in size and light in weight. Usually, after using SMT, the volume of electronic products is reduced by 40% to 60%, and the weight is reduced by 60% to 80%.
2. High reliability and strong anti-vibration ability
Since SMC and SMD have no leads or short leads, and are firmly attached to the surface of the PCB, they have high reliability and strong vibration resistance. Good high frequency characteristics.
3. It is easy to realize automation and improve production efficiency.
Compared with THT, SMT is more suitable for automatic production. For example, THT needs different plug-in machines (automatic plug-in machines, horizontal plug-in machines, vertical plug-in machines, taping machines, etc.) according to different components.
4. Can reduce costs.
Reduce the cost of manufacturing PCB; no-lead or short-lead SMC, SMD saves lead materials; omission of wire trimming and bending processes reduces equipment and labor costs; improvement of frequency characteristics reduces RF debugging costs; good reliability Reduce repair costs. Generally, the use of SMT in electronic equipment can reduce the total cost of the product by 30% to 50%.
