SMT production / storage environment requirements:

1. SMT ambient temperature is controlled at 23 ° C to 27 ° C

2. SMT environment humidity is controlled at 40%-70%

3. SMT environment dustproof requirements: All personnel entering the SMT workshop must wear electrostatic clothing and wear an electrostatic cap to enter the workshop through the air shower door.

4. SMT environment anti-static requirements: Class I electrostatic operation area, static control target <100V If the customer has special tightening static control requirements, it is classified as level 0 electrostatic operation area, static control target <50V and posted at SMT entrance Static identification.
