Environment PolicyPCB / PCBA production equipment and SMT patch processing technology have extremely high requirements for the workshop's power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static, and production personnel's wearing accessories. And the workshop environment is required to be clean and tidy, the purpose is to reduce the health hazards of oil and dust to the workshop workers. At the same time, environmental protection and greening are the pursuit and goals of modern development, because an environmentally friendly and greening environment can reduce or control the generation of pollution sources. For the normal operation of the equipment and the high standard requirements of the production process, the workshop environment temperature is controlled at 20 ± 3 degrees Celsius, the relative humidity is 45%-70% RH and equipped with temperature and humidity adjustment equipment. Both reflow soldering and wave soldering equipment have exhaust and flue gas emission requirements, and exhaust fans are configured according to equipment requirements. 
The power supply voltage and power meet the requirements of PCB and PCBA processing equipment. The voltage is stable, single-phase AC220V (220±10%, 50/60Hz), three-phase AC380V (380±10%, 50/60Hz). The power of the power supply is more than twice the power consumption. The lighting in the workshop is 1000-1200 LUX. At the same time, local lighting will be installed in work areas such as overhaul, rework, and measurement. Precision electronic components such as ICs involved in PCBA production are often easily damaged by static electricity. Therefore, electrostatic protection is also very important. Personnel entering the workshop must wear anti-static overalls, work caps, and shoes with shoe covers. Anti-static bracelet, etc. 
The workshop should be kept clean and sanitary, free of dust and corrosive gases. The production workshop has cleanliness control, and the cleanliness is controlled at: 500,000.
