1. The SMT patch processing factory needs to set up an appropriate temperature and humidity meter for monitoring based on the size of the facility during processing.
2. Speaking of SMT patch processing, many people are familiar with it. This technology and process are quite common in the electronic assembly industry. Typically, the electronic products seen or used contain PCB circuit boards. Various capacitors are designed according to different circuit diagrams, and these electrical components require various SMT chip processing techniques. There are specific requirements for the production workshop during this processing.
3. When processing SMT chips on PCB boards, manufacturers need to set up a suitable temperature and humidity meter according to the facility’s size for effective monitoring.
4. Generally, SMT patch production workshops have certain requirements for the production environment. First, the load-bearing capacity, vibration, and noise levels of the plant must be considered. The plant floor should support a load-bearing capacity of more than 8kN/m²; vibrations should be controlled within 70dB, and values exceeding this should not surpass 80dB; noise levels should be maintained within 70dBA. Power supply requirements generally include single-phase AC220 (220±10%, 0/60Hz), three-phase AC380 (380±10%, 50/60Hz), with the power supply capacity needing to exceed twice the power consumption.
5. The SMT patch processing factory must install an appropriate temperature and humidity meter based on the plant’s size for monitoring purposes during processing.
6. Next, let’s consider the air source requirements. The air source pressure should be configured according to equipment needs. The factory’s existing air source can be utilized, or a separate oil-free compressed air machine may be installed. Typically, the pressure should exceed 7kg/cm². Clean, dry, purified air is necessary, so compressed air must undergo degreasing, dust removal, and water separation treatments. Air ducts should be made from stainless steel or pressure-resistant plastic.
7. There are also requirements for exhaust air. Reflow soldering and wave soldering equipment must be equipped with exhaust fans. For all hot air stoves, the minimum exhaust duct flow rate should be 500 cubic feet per minute (14.15m³/min).
1. PCB manufacturers need to set up appropriate temperature and humidity meters for monitoring based on the size of the plant during SMT processing.
2. Lighting: The ideal illuminance in the workshop is 800–1200 lux, with a minimum requirement of 300 lux. If the illuminance is insufficient, install local lighting in inspection, repair, measurement, and other work areas.
3. Working environment: Maintain cleanliness and hygiene, ensuring no dust or corrosive gases in the workshop. The production workshop should have cleanliness control with standards of 500,000; the ambient temperature should be maintained at 23±3°C, generally between 17–28°C, and relative humidity at 45%–70% RH. Equip the workshop with suitable temperature and humidity meters for regular monitoring and facilities for adjusting temperature and humidity.
4. SMT patch processing reveals that the requirements for the production workshop during patch processing are quite high, particularly concerning cleanliness, air source, exhaust, and lighting.
