1. In PCB manufacturing, the workshop serves as the factory’s main artery, with most production and processing activities occurring there. The environment of the workshop and the quality of its personnel are crucial in showcasing the factory’s corporate culture and excellence. Today, let’s explore the workshop to understand the requirements for its environment and personnel.
2. PCBA Production Workshop
PCBA small-batch proofing and PCBA production equipment, along with SMT patch processing technology, impose specific requirements on power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static measures, and the personal protective equipment worn by production personnel. The workshop environment should be clean and orderly to minimize health hazards such as oil and dust exposure for workers. Additionally, modern development emphasizes environmental protection and greening as key goals. A green environment helps reduce or control pollution sources. Large material particles mainly affect visibility within the workshop, which can impair workers’ operations and hinder management oversight. Furthermore, visible particles often significantly reduce the service life of air-conditioning systems and workshop equipment.
Next, let’s examine the specific requirements for the workshop environment.
1. Temperature and Humidity Requirements:
For optimal equipment operation and high standards in the production process, it is ideal to maintain the workshop temperature at 23±3 degrees Celsius and the relative humidity between 45% and 70% RH.
2. Ventilation Capacity:
Reflow soldering and wave soldering equipment both have specific exhaust and flue gas emission requirements. The exhaust fan should be configured according to these equipment requirements. For all hot air reflow ovens, the exhaust duct should generally have a minimum airflow rate of 14-15 m/min.
3. Power Requirements:
The power supply voltage and capacity must meet the requirements of the processing equipment. Voltage stability is crucial; typically, this requires single-phase AC 220V (220±10%, 50/60Hz) or three-phase AC 380V (380±10%, 50/60Hz). If these conditions are not met, a regulated power supply must be installed. The power supply should exceed the power consumption of the device. Additionally, the placement machine requires independent grounding, typically achieved through a three-phase five-wire connection. Due to the high speed of the placement machine, it can generate electromagnetic interference when connected with other equipment, which can impact its operation and placement accuracy.
4. Static Protection Requirements:
Precision electronic components, such as ICs used in PCBA production, are highly susceptible to damage from static electricity. Therefore, static protection is critical. Generally, personnel entering the workshop must wear anti-static overalls, work caps, and shoe covers. They should also use anti-static wristbands.
PCBA Production Workshop:
The workshop is the heart of the PCB factory and the primary environment for most staff. It is the factory’s responsibility to ensure the health and safety of its employees. Regular training on workshop environment and personnel requirements is essential, especially for small batch PCBA proofing.
