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 within70dBA.
2. Power
Generally, single-phase AC220 (220±10%,0/60Hz) and three-phase AC380 (380±10%, 50/60Hz) are required. The power of thepower supply should be more than twice the power consumption.
3. Air source
The pressure of the air source can beconfigured according to the requirements of the equipment. The air source ofthe factory can be used, or an oil-free compressed air machine can beconfigured separately. Generally, the pressure is greater than 7kg/cm2. Cleanand dry purified air is required, so the compressed air needs to be degreasing,dusting, and water removal treatment. Use stainless steel or pressure-resistantplastic pipes for air ducts.
4. Exhaust
Reflow soldering and wave solderingequipment need to be equipped with exhaust fans. For all hot blast stoves, theminimum flow rate of the exhaust duct is 500 cubic feet per minute(14.15m3/min)
5. Lighting
The ideal illuminance in the workshop is800~1200LUX, at least not less than 300LUX. When the illuminance is low,install local lighting in the inspection, repair, measurement and other workareas.
6. Working environment
The workshop should be kept clean andsanitary, free of dust and corrosive gases. The production workshop should havecleanliness control, and the cleanliness should be controlled at: 500,000.
The best ambient temperature in theproduction 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 thermometerand hygrometer for regular monitoring and temperature adjustment. Humidityfacilities.
1. Purpose
Implement proper management of the workingenvironment and comprehensively strengthen the daily control of PCBA to ensurequality and ensure that the environment will not affect product compliance.Improve efficiency and brew a good working environment.
2. Scope of application
It is suitable for the management of theworking environment of the PCBA workshop product realization process.
