Generally speaking, the design requirements of the production environment determine the quality of the product to a certain extent. Today we mainly understand the environmental requirements of the SMT production workshop, mainly from the aspects of workshop temperature, noise treatment, electrostatic protection, workshop purification, etc. .

1. A bright and clean workshop environment is an important guarantee for product production quality. Some auxiliary materials such as SMT production equipment, SMT patch glue, solder paste, etc. should be used within a certain temperature range to maintain specific special performance and good craftsmanship. Sex. Generally, the temperature of the workshop should be controlled within the range of 18℃~26℃. At the same time, attention should be paid to the fire safety of the production area and warehouse. For example, the design, construction or transformation of the workshop should be reviewed by the fire department.

2. SMT equipment generally uses compressed air and electric power as dual power, and the requirements for the cooperation of gas and electricity are relatively strict. Reflow soldering, wave soldering, etc. are all equipment that consumes a lot of electricity, and their shutdown and startup will have a certain impact on other electrical equipment.

3. SMT equipment will produce a certain amplitude of vibration during operation, especially when large-scale high-speed placement, the vibration caused to the plant is more obvious. According to the "Urban Area Environmental Vibration Standard GB 1070-88", daytime vibration should be controlled within 70db, and the maximum value should not exceed 80db. Too much vibration is not only detrimental to the safety of the plant structure, but also interferes with the operation of other equipment and causes discomfort to the staff.

In addition, since it is a production workshop, it is indispensable that there are multiple machines operating at the same time. If some noise reduction materials are not used, the workshop noise will be very loud. The noise control standard should refer to the "Industrial Enterprise Noise Control Design Specification GBJ 87-85", and the noise value in most areas of the SMT production workshop should be controlled within 70db.

4. Regarding electrostatic safety protection: We have mentioned its importance before, and the SMT production workshop is no exception. It should be designed in accordance with the standards of electrostatic safe working area. At the same time, the production area should be equipped with electrostatic protection equipment to maintain a good production environment. .

5. With the development of productivity, environmental pollution and resource consumption caused by human production activities are not conducive to human health and sustainable development. The pollution sources in the SMT production workshop mainly come from the smoke and dust generated by wave soldering, reflow soldering and manual soldering (the main components are lead/tin vapor, nitrogen oxides, ozone and carbon monoxide and other harmful gases), of which lead vapor is the most harmful to human health Therefore, effective measures must be taken to purify the air in the workshop, such as installing smoke filters to absorb and filter out harmful gases.

The last one is the problem of electromagnetic radiation. Excessive electromagnetic radiation can cause harm to the human body. Therefore, when selecting or purchasing SMT equipment, the electromagnetic radiation that may be generated should be required to ensure the physical safety of the production personnel.

In short, the SMT production workshop must put safety first and quality second. At the same time, the SMT production workshop should follow the people-oriented and "green" production philosophy.

The above is the content of SMT production workshop design requirements introduced by Sanjing, I hope it can be helpful to everyone!
