What are the characteristics of SMT chip processing

2021-1-4 14:12:37  

SMT processing is surface mount technology. The specific content refers to the technology of placing flake components or miniaturized components suitable for surface mount on the surface of PCB board as required and then welding them with reflow welding and other welding processes to complete the assembly of electronic components.In THE SMT circuit board, solder joints and components are on the same surface of the board, so in the SMT SMT machined PCB board, the through-hole is only used to connect the two sides of the circuit board wire, the number of holes is much smaller, the diameter of holes is much smaller.Such a design can greatly improve the density of PCB components.

1. Miniaturization

The size and volume of flake components used in SMT chip processing is much smaller than that of traditional plug-in components, which can generally be reduced by 60% ~ 70% or even 90%.60 to 90 percent weight loss.This can meet the need for the miniaturization of electronic products.


2. High signal transmission speed

SMT PCB processed by SMT has a compact structure and high mounting density, which can achieve the effect of short connection and small delay, thus achieving high speed signal transmission.At the same time can make electronic products more vibration resistance, impact resistance.

3. High-frequency characteristics

Components for SMT chip processing are generally lead-free or short-lead, which reduces the distribution parameters of the circuit and thus reduces RF interference.


4. Conducive to automatic production

SMT chip processing chip components with dimensions standardization, serialization and consistency of welding conditions and other characteristics can make SMT chip processing highly automated.


5. Low material cost

The packaging cost of most PCBA SMT processing components is lower than that of plug-in processing components of the same type and function.


6. High production efficiency

SMT technology simplifies the production process of electronic complete machine products and reduces the production cost.The whole production process is shortened and the production efficiency is improved.
