Environment design of SMT dust free workshop

The environmental design of SMT dust-free workshop should pay attention to three aspects: temperature. humidity and air cleanliness.

• Temperature: workers assembly precision electronic components in the dust-free workshop of SMT.so we should make the indoor temperature between 17 ℃ ~ 28 ℃. and the minimum requirement is 15 ℃ ~ 35 ℃.

• Humidity: too high or too low humidity will affect the quality of electronic components. Too high humidity will cause the material to get damp and become unidentified. Too low humidity will produce static electricity.

Specifically. we should control the humidity in the dust-free workshop of SMT within 45% – 70% RH. and the minimum requirement shall be 30% – 55% RH or 40% – 80% RH.

• Air cleanliness: as mentioned above.SMT dust-free workshop is mainly due to surface mounting or surface assembly of precision electronic components.

If the dust content in the air is too large. it will inevitably affect the assembly or assembly of materials. and increase the wear rate of equipment. resulting in equipment failure.

The minimum standard of indoor air cleanliness is 100000. the carbon dioxide content is controlled below 1000ppm. and the carbon monoxide content is controlled below 10ppm.
