Pcb manufacturing workshop working environment requirements

PCB manufacturing assembly production equipment is a high-precision electromechanical integration equipment. Equipment and process materials have certain requirements for environmental cleanliness, temperature and humidity. In order to ensure the normal operation of equipment and the quality of pcb assembly, the following requirements are imposed on the working environment.

 

The workroom is kept clean and free of dust and corrosive gases. The air cleanliness is 100000 (BGJ73-84);there must be a certain amount of fresh air in the air-conditioning environment,, try to control the CO2 content below 1000*10 minus six, and the CO content is controlled below 10*10 minus six to ensure Human health.

 

 

The environment temperature of the Pcb manufacturing assembly workshop is optimized at 23 °C ± 3 °C. Generally, it is 17 °C-28 °C, the limit temperature is 15-35 °C (the best environment temperature of the printing workshop is 23 °C ± 3 °C)

The relative humidity is RH45%-70%.

According to the above conditions, due to the dry climate in the north and the large wind and sand, the SMT production line in the north needs to use double-glazed workshops, generally equipped with air conditioning.
