[labnetwork] Cleanroom ISO 7 (Class 10,000) Specification

[Weaver, John R]

YuYing -

The specifications for your cleanroom will depend on the process and research needs and the equipment design and layout. You certainly want to comply with ISO 14644, but also need to specify any other parameters that are critical to your process. From an airflow standpoint, you will most likely want to specify temperature, humidity, and air changes per minute as well as the particle concentration specified in the ISO spec. Whether you specify unidirectionality of the airflow depends on your equipment layout and airflow design. In addition, you may want to specify vibration, static levels, EMI levels, and anything else that will affect your process and equipment. If you drop me a note that describes the equipment and layout as well as the process parameters, I should be able to help.

I'm not trying to advertise, but since you are in Amherst you have an easy opportunity to take a course I'm teaching in Boston in April. ESTECH is the foremost conference on cleanrooms, and ESTECH 2015 will be held in Danvers April 27-30, 2015. I'll be teaching a tutorial on Cleanroom Basics on Monday, April 27. It's an all-day tutorial that covers all aspects of cleanrooms and a glance at their operation. I think it would be very useful to you. There is more information at iest.org. Click on Meetings, then ESTECH.

Does anybody have a cleanroom specification and can share it with me?

We need to build a clearnroom in our new Life Science Center, and this clean room is housing our Roll to Roll facilities for flexible electronics fabrication research.  We are thinking of a class 10,000 cleanroom, after considering the cost and efficiency compromise.

Many of you manage cleanrooms.  When the cleanrooms were built, are they just satisfy the ISO 14644 standard, or you have to specify the following
items:
particulates, air changes, air flow patterns, static control and acceptable humidity ranges....

We currently have a couple of Soft Wall Cleanrooms, and there is some rusty and deposition on metals.  We are not sure whether is caused by clean room air or other factors.

Thank you very much.
