Clean room

[badsector]

Hi,

Is there a way to build your own clean room, because i know that class 100 clean room is needed for opening hdd, so i know some values (minimum dust amount) but don't know which filter for which size room etc....

Can anybody help ?
Thanks

There is no standard for the size of clean room,but the equiment are strickly choosen.Operators should wear uniform ,gloves.It's similiar like ICU in hospital or Operation Room.

Just my opinion.

Far easier to use a clean cabinet. An infant incubator is ideal.

With a cabinet, you don't need to wear all the clothing, it's generally way, way cleaner (in theory, at least) than a Class 100 clean room, and if you need to get up quickly to go to the loo, you simply pull your arms out of the sleeves and go...... none of the undressing and decontamination routines to go through as with a clean room.

Also transportable.

I agree with Odiferous : make a CLEAN CABINET. I am trying to design something useful, using common, cheap transparent Perspex - similar to plexiglass but more resistant). Class 100 gloves and materials are readily available at electronics distributors, I found also some wafer handling tools (for handling silicium wafers during chip fabrication) thet could help.
The main problem is the air filter . According to a colleague an air filter for a class 100 small clean room cost about $1000 and the filtering material must be replaced - in order to maintain the same class - about 1 time per year according to the amount of the air that has passed on it and other factors... but for us the purposal is to have sufficient cleanliness for opening the drive, make te operations you have to do e.g. head stack inspection, replacement etc. , close it and try to get the data back. The drive has to be discarded anyway!

Regards.

Thanks for your replies.

Whitpapers say that for a class 100 clean room, class 100 HEPA filter is needed. And a class 100 cleanroom maintains less than one hundred particles larger than 0.5 microns in each cubic meter of air space. Now i am trying to find this kind of HEPA filter (of course cheap one), and i will inform you.

I made 1,5x2x2 m glass room, and bought one BAP825 type tower filter and bap223 desktop filter. For this size of room, it supplies 0,3 mikron per m3 and %99 cleanness.

I'm trying this system now....
