Do you know what the air source requirements of the SMT chip processing workshop are?

Does the production workshop for SMT chip processing have requirements for the environment? Does it require a dust-free environment? The specific requirements are: first the load-bearing capacity, vibration, and noise requirements of the plant, the load-bearing capacity of the plant road surface should be greater than 8KN/m2; the vibration should be manipulated at 70dB Within the limit, the limit value is not more than 80dB; the noise should be controlled within 70dBA; the switching power supply generally requires single-phase AC220, three-phase AC380, and the output power of the switching power supply is greater than 1B of the functional loss.

Next is the air source requirements of the SMT patch processing workshop. The air source pressure is equipped according to the requirements of the equipment. The air source of the factory can be used, or a separate oil-free compressed air machine can be equipped. Generally, the pressure is greater than 5kg/cm2. Clean and dry purified air is required, so the compressed air must be degreasing, dusting, and sewage treatment. Use stainless steel plates or pressure-resistant plastic hoses as gas pipelines. There are also requirements for an exhaust system, and the reflow oven and wave soldering machine must be equipped with exhaust fans. For the full hot blast stove, the low flow value of the exhaust system pipe is 500 cubic inches per minute.

The ideal lighting number in the SMT patch processing workshop is 800-1200LUX, not less than 300LUX. When the lighting level is low, install some lighting in areas where the inspection, maintenance, and accurate measurement are working. The SMT patch processing production workshop must maintain daily cleaning, no dust, no corrosive vapor. The production workshop needs to have cleanliness control, and the cleanliness control is: 500,000; the working temperature of the production workshop is preferably 23±3℃, generally 17-28℃, and the air humidity is 45%-70%RH; The specification and size of the production workshop are set with a suitable thermometer and hygrometer, which are monitored regularly and equipped with equipment for adjusting temperature and humidity.
