The Requirements of SMT workshop production environment

 

There are many first-time users of SMT equipment, but they are not very familiar with the requirements of the working environment of SMT production equipment, so we make some research and show u as following. The first thing to tell you is that SMT production equipment is high-precision electromechanical Integrated equipment, equipment and process materials have certain requirements for environmental cleanliness, humidity, and temperature. In order to ensure the normal operation and assembly quality of the equipment, the working environment has the following requirements:

 

1, The load-bearing capacity, vibration, and noise requirements of the plant should be greater than 8KN/m2.

 

Vibration should be controlled within 70dB, and the maximum value should not exceed 80dB. Noise should be controlled within 70dBA.

 

2, Power supply

 

Generally, single-phase AC220 (220±10%, 0/60Hz) and three-phase AC380 (380±10%, 50/60Hz) are required. The power of the power supply should be more than twice the power consumption.

 

3, Air source

 

According to the requirements of the equipment, the pressure of the air source can be configured. The air source of the factory can be used, or an oil-free compressed air machine can be configured separately. Generally, the pressure is greater than 7kg/cm2. Clean and dry purified air is required, so the compressed air needs to be degreasing, dusting, and water removal treatment. Use stainless steel or pressure-resistant plastic pipes for air ducts.

 

4, Exhaust

 

Reflow soldering and wave soldering equipment must be equipped with exhaust fans. For all hot blast stoves, the minimum flow rate of the exhaust duct is 500 cubic feet per minute (14.15m3/min)

  

5, Lighting

 

The ideal lighting level in the workshop is 800~1200LUX, at least not less than 300LUX. When the lighting level is low, install local lighting in the inspection, repair, measurement and other work areas.

  

6, Working environment

 

The workshop is kept clean and sanitary, free of dust and corrosive gases. The production workshop should have cleanliness control, and the cleanliness should be controlled at: 500,000.

 

The best ambient temperature in the production workshop is 23±3℃, generally 17~28℃, and the relative humidity is 45%~70%RH. According to the size of the workshop, set a suitable thermometer and hygrometer for regular monitoring and temperature adjustment. Humidity facilities.
