— AOI equipment manufacturer SMT produces aoi equipment, specializing in the design, production, sales and service of electromechanical equipment (AOI, aoi automatic optical detector, aoi visual detector, tin slag reduction machine, SMT peripheral products and motor automatic tester) It is a high-precision mechatronics equipment. The equipment and process materials have certain requirements for the cleanliness, humidity and temperature of the environment. In order to ensure the normal operation and assembly quality of the equipment, the following requirements for the working environment are:

Power supply: The power supply voltage and power must meet the equipment requirements.

The voltage should be stable, requirements:

Single-phase AC220 (220±10%, 50/60 HZ)

If the three-phase AC380V (220±10%, 50/60 HZ) does not meet the requirements, a regulated power supply needs to be configured, and the power of the power supply should be more than double the power consumption. Temperature: Ambient temperature: 23±3℃ is the best. Generally 17 ~ 28 ℃. The limit temperature is 15～35℃ (the ambient temperature of the printing workshop is 23±3℃ is the best) Humidity: Relative humidity: 45～

Working environment: The workplace should be kept clean and hygienic, free of dust and corrosive gases.​​

Air cleanliness is 100000 (BGJ73-84);

In an air-conditioned environment, there must be a certain amount of fresh air, try to control the CO2 content below 1000PPM, and control the CO2 content below 10PPM to ensure human health. Anti-static: The production equipment must be well grounded, and the three-phase five-wire grounding method should be adopted and grounded independently. The floor of the production site, workbench pads, chairs, etc. should meet the anti-static requirements. Exhaust: Reflow and wave soldering equipment has exhaust requirements. Lighting: There should be good lighting conditions in the workshop. The ideal illumination is 800LUX×1200LUX, at least not less than 300LUX.​​

Requirements for SMT production line personnel: The operators of each equipment in the production line must pass professional technical training and be qualified, and must be proficient in the operating procedures of the equipment.​​

Operators should operate in strict accordance with the “safety technical operating procedures” and process requirements.
