Q Good High Frequency Effects
A Because the components have no lead or short lead, the distributed parameters of the circuit are naturally reduced and the RF interference is reduced.
Q High Signal Transmission Speed
A SMT assembled components are not only compact in structure, but also high in safety density. The assembly density can reach 5.5~20 solder joints per square centimeter when the PCB is pasted on both sides. SMT assembled PCBs can realize high speed signal transmission due to short circuit and small delay. At the same time, SMT assembled PCBs are more resistant to vibration and impact. This is of great significance to realize ultra-high speed operation of electronic equipment.
Q Realize Miniaturization
A The geometric size and volume occupied by SMT electronic components are much smaller than that of through-hole interpolation components, which can be generally reduced by 60%~70%, and some components can even be reduced by 90% in size and volume. At the same time, the weight of components can be reduced by 60%~90%.
Q Simplify the Production Process & Reduce the Production Cost
A When mounting on the PCBs, the leads of components need not be bent, shaped or cut short, so that the whole process is shortened and the production efficiency is improved. The processing cost of the same functional circuit is lower than that of through-hole interpolation, which can generally reduce the total production cost by 30%~50%.
Q Low Materials Cost
A Due to the improvement of production equipment efficiency and the reduction of packaging material consumption, the packaging cost of most SMT components has been lower than that of THT components with the same type and function. Consequently, the sales price of SMT components is lower than that of THT components.
Q SMT is beneficial to automatic production, improving yield and production efficiency
A The standardization, serialization and consistency of welding conditions of chip components make SMT highly automatic. The component failure caused by welding process will be greatly reduced and the reliability will be improved.
