As Jim, says, in case you have to manage high RH% in your facility, if you
need to correctly handle, storage, package,use, etc, your:
- MSD (Moisture Sensitive Device), the IPC/J-STD-033C is the right standard
who gives you guidelines.
- PCB ( also them need to be protected against moisture absorption, mainly
if in lead free reflow environment) take in consideration the IPC-1601
For a correct protection against ESD, the Standard mainly followed are:
- USA : ANSI 20.20, others EIA, JEDEC,
- Europe : mainly IEC-EN-61340-5-1

Oggetto: Re: [TN] Humidity levels within SMT/PCA factories.
Can I assume you are having problems with too much humidity causing damage
to components when subjected to reflow temps? I recall there is a joint
IPC/JEDEC (at least I think that's who published the document) covering
storage of components for SMT. Or it could be an EIA standard.

I think there is an ESD Association standard that covers it but most control
systems have a minimum value of 30%. When values fall below that,
additional ESD measures kick in. The most common being spray misters to
increase relative humidity.

Hi all,
Is there a standard written that covers required humidity levels within an
SMT/PCA plant?
What levels do others maintain in their factories where humidity is an
issue?
Thanks,
Jim
