What are the requirements for the workshop environment for PCBA processing?
The PCBA production equipment and SMT chip processing technology for PCBA processing have certain requirements on the workshop's power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static, and the wearing accessories of production personnel.
1. Temperature and humidity requirements
For the normal operation of the equipment and the high standard requirements for the production process, it is best to control the ambient temperature of the workshop at 23±3 degrees Celsius, and the relative humidity of 45%-70%RH is the best.
2. Ventilation capacity
Both reflow soldering and wave soldering equipment have exhaust and flue gas emission requirements, and exhaust fans should be configured according to equipment requirements. For a full hot blast stove, the minimum flow rate of the exhaust duct is generally required to be 14-15m/min.
3. Power requirements
The power supply voltage and power meet the requirements of PCBA processing equipment. Voltage stability, generally requires single-phase AC220V (220±10%, 50/60Hz), three-phase AC380V (380±10%, 50/60Hz). If the requirements are not met, a regulated power supply should be configured, and the power supply power is greater than the power consumption of the device. The power supply of the placement machine requires independent grounding, and generally a three-phase five-wire wiring method should be used. Because of the high speed of the placement machine, it is easy to generate electromagnetic interference when it is connected with other equipment, which affects the normal operation and placement accuracy of the placement machine.
Fourth, electrostatic protection requirements
Precision electronic components such as ICs involved in PCBA production are often easily damaged by static electricity, so electrostatic protection is also very important. Usually, personnel entering the workshop must wear anti-static work clothes and work caps. Anti-static bracelet.
Shenzhen Baiqiancheng Electronics Co., Ltd. has operated its own factory for more than 19 years. It strictly controls the workshop environment and regularly trains employees. The good environment and personnel quality of our workshop demonstrate the cultural conservancy and excellence of our company.
