Hi Victor,



IPC has just updated J-STD-001 to Rev E.



In RevE, the temperature and humidity in a factory are recommended as following:



For operator comfort and solderability maintenance, the temperature should be maintained between 18°C [64.4°F] and 30°C [86°F] and the relative humidity should not exceed 70%. For process control, more restrictive temperature and humidity limits may be required.



In order to control the factory environment, I think you should buy J-STD-001E. It's not free.



If you need to buy any IPC documents, please contact me.

Please refer to IPC J-STD-001 4.2.2.

Temperature control spec is 18ºC ~ 30ºC & Humidity is 30% ~ 70%.

Actually We need to control humidity not high than 60% since there are some MSD component using in factory.

Dear all,



请教一个SMT车间温湿度的控制要求，引用IPC什么标准?当前我们是18-26.度湿度是40%-60%，总是不达标，想修改这个范围，但不知道引用什么标准。
