Specific requirements for the workshop environment by PCBA

The workshop is the main artery of the PCBA factory, and most of the production and processing are carried out inside the workshop. For a PCBA factory, the workshop environment and personnel quality are key to showcasing its corporate culture and excellence. So today, let’s walk into the workshop and understand the requirements of PCBA processing for the workshop environment and personnel.

1、 Temperature and humidity requirements
In order to ensure the normal operation of the equipment and meet high standards for production processes, it is best to control the workshop environment temperature at 23 ± 3 degrees Celsius and the relative humidity at 45% -70% RH.
2、 Ventilation capacity
Both reflow soldering and wave soldering equipment have exhaust and smoke emission requirements, and exhaust fans should be configured according to the equipment requirements. For a fully 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) and three-phase AC380V (380 ± 10%, 50/60Hz). If the requirements are not met, a stable power supply needs to be configured, and the power supply power is greater than the device power consumption. The power supply of the SMT machine requires independent grounding and generally adopts a three-phase five wire wiring method. Due to the high operating speed of the SMT machine, it is prone to electromagnetic interference when connected to other equipment, which affects the normal operation and installation accuracy of the SMT machine.

4、 Requirements for electrostatic protection
The precision electronic components such as ICs involved in PCBA production are often easily damaged by static electricity, so static electricity protection is also very important. Usually, personnel entering the workshop must wear anti-static work clothes, work hats, shoe covers, and anti-static wristbands.
