What is smt clean room

Smt (short for SurfaceMountedTechnology) is surface mount technology (surface mount technology), which is a popular technology and process in the electronics assembly industry.

What are the characteristics of smt:

The assembly density is high, the size of the electronic product is small, and the weight is light. The volume and weight of the patch components are only about 1/10 of that of the conventional plug-in components. After the smt is generally used, the volume of the electronic product is reduced by 40% to 60%, and the weight is reduced by 60%. 80%. High frequency characteristics, reduced electromagnetic and radio frequency interference, high reliability and strong anti-vibration capability. The solder joint defect rate is low, and it is easy to automate and improve production efficiency. Reduce costs by 30% to 50%. Save materials, energy, equipment, manpower, time, etc.

Smt basic process components:

Printing (or dispensing) --> Mounting --> (curing) --> reflow soldering --> cleaning --> detection --> repair

So in summary: smt workshop as a clean room in general to meet the needs of the production process, and production equipment, production environment is closely related, the main advantages are as follows:

1. To prevent dust, there is a lot of floating dust in the air.

2. Prevent body hair and other hair from falling onto the product, and strictly need to bring gloves, so as to ensure product quality.
