A dust-free workshop refers to the removal of particles, harmful air, bacteria, etc. in the air within a certain space, and the indoor temperature, cleanliness, indoor air pressure, air velocity and distribution, noise, vibration, lighting, and static electricity are controlled within the required range Inside, and given a specially designed workshop. That is to say, no matter how the external ambient air conditions change, the room can ensure the stability of the required cleanliness, temperature and humidity, air freshness, wind pressure and other performance parameters.

SMT workshop temperature and humidity standards: temperature 22±2℃ humidity 50±5%

The first is to ensure that the solder paste can work in a better environment. The temperature will affect the activity of the solder paste and have a certain impact on the activity of the added flux and related solvents. Too high temperature will increase activity, and ultimately affect the effect of screen printing and reflow. Prone to phenomena such as false soldering and non-glossy solder joints. The high humidity causes the solder paste to inhale moisture in the air. If too much moisture is absorbed, it will cause reflow to produce solder slag and continuous soldering. When mounting, if the humidity is too low, static electricity will be generated, which will cause IC micro-short circuit and too many defective products.

Temperature and humidity standards for dust-free workshops of electronics manufacturing industry: Temperature 22±2℃ Humidity 55±5%

Chip production and processing workshops, integrated circuit clean rooms and disk manufacturing workshops are important components of clean rooms in the electronics manufacturing industry. Because electronic products have extremely strict requirements on the indoor air environment and quality during the manufacturing and production process, they mainly control particles And metal dust is the main object, and strict regulations are also made on the temperature and humidity, fresh air volume, and noise of the environment. (Special electronic dust-free workshops have relevant temperature and humidity regulations).

Standard of temperature and humidity in filming workshop: temperature 21±2℃, humidity 60±5%

Strictly speaking, the filming workshop needs a 100-level dust-free workshop. In fact, few manufacturers do it. Many manufacturers build a clean shed in a 10,000-level workshop to achieve cleanliness due to cost factors. Claim. Firstly, the air-conditioning ventilation system should control the dust particles and microorganisms in the air and ensure the freshness of the air (air-conditioning structure: fresh air and return air), and then control the cleanliness of production materials and the cleanliness of entering employees. Eliminate the introduction, generation and retention of pollutants.
