We use dry boxes manufactured by DMS Clean Room Products in Lawrence, MA. The phone number on the tag is (508)683-2325, but I think their area code changed to either 978 or 781 recently. We flow dry nitrogen through the box in order to ensure that

Dave, Most dust and other crud is actually generated inside a plant. While working at another company they brought in consultants for this same issue. I don't remember the exact amount but only around 20% comes from the outside. Unless you are

Hi, I used to run a clean room, and it's right, most of the dust is created internally. You will need to add some HEPA filtering to the area, and an air handling unit that can control temp and humidity as well to get correct environmental control.

I would concur about clean room problems especially with a high mix changeover environment. Paper tape is horribly dusty and just the cover tape pulling away generates a lot of dust. There was a day when everyone said paper was on the way out for

Hi, Use nitrile or latex gloves for handling your product from your pre-coating cleaning step onward. In my opinion, conformal coating should be isolated from the rest of the factory floor. I'm not saying you need a clean room or even a white room.

Hi, It depends on smallest pitch size of your components. For the 0.3 um, 0.5 um, etc. sizes could be mentioned on Clean Room. For example; for ISO-7 standart (Class 10,000) higher than 5um is not acceptable, however 1mm can acceptable to describ
