Before the start of the factory, all areas must be disinfected and sterilized to ensure the protection and safety of the workers inside the factory, industrial safety inspection, fire inspection and other start-up inspections. Then ask you and your equipment supervisor to pay attention to the following:

SMT production line:

(1) Turn on the air conditioner in advance, and the temperature and humidity meet the requirements.

(2) Turn on the air source switch of the workshop and confirm that the air pressure meets the requirements.

(3) Confirm that the main power supply of workshop equipment is off.

(4) Confirm that the main power supply voltage of workshop or production line meets the requirements, and turn on the switch.

(5) And turn on the power of the equipment one by one. After the equipment is fully turned on, turn on the next device one by one.

(6) After the power supply of the equipment is turned on, the original point will return and the heat engine will run in the test mode.

(7) Please follow the above process. If there is any problem, please contact the equipment manufacturer at any time.

 

In order to reduce the start-up failure rate after the festival, Dafton-SMT shares the following attentions of SMT equipment.

Firstly, confirm whether the temperature and humidity of SMT workshop exceeds the environmental requirements, whether the equipment is affected by moisture, and whether there is dew. In a relatively cold environment, do not rush to raise the temperature of SMT workshop first. The equipment is easy to produce dew. (it is forbidden to turn on the power supply at this time). Specific practices refer to the different SMT workshop environment of each factory.

According to the different degree of moisture, the time of dehumidification treatment of the equipment is selected (check whether it is normal by the industrial control electrical part), open the front and rear chassis cover of the equipment (pay attention not to touch the wires in the corner), place the fan at 0.5 m in front of the chassis for blowing (purpose: blow off the moisture in the equipment cabinet with the air blower, note: do not use hot air), and select 2-6 hours for blowing according to the degree of moisture For wind operation, switch on the power supply after the dehumidification operation, and start the machine after checking that there is no error, but do not return to the original point. Warm up at the return point about 30 minutes to 60 minutes after starting up.
