PCBA production equipment and PCBA processing technology have certain requirements for the workshop's power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static, and production personnel's wear accessories.

1. Power requirements

The power supply voltage and power meet the requirements of PCBA processing equipment. The voltage is stable, generally requires single-phase AC220V (220±10%, 50/60Hz), three-phase AC380V (380±10%, 50/60Hz). If it does not meet the requirements, a regulated power supply must be configured. The power supply is greater than the power consumption of the device.

The power supply of the placement machine requires independent grounding. Generally, a three-phase five-wire connection method should be adopted. Because of the high speed of the placement machine, it is easy to produce electromagnetic interference when connected with other equipment, which affects the normal operation and placement accuracy of the placement machine.

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 all hot blast stoves, the minimum flow rate of the exhaust duct is generally required to be 14-15m/min.

3. 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 best when the relative humidity is 45%-70%RH.

4. Electrostatic protection requirements

Precision electronic components such as ICs involved in PCBA production are often easily damaged by static electricity, so static protection is also very important. Generally, personnel entering the workshop must wear anti-static overalls, wear work caps, and shoes need to be covered with shoe covers. Anti-static bracelet.
