Some portable clean rooms are hand carried. Other portable clean rooms can be walkable and self-contained. Consisting of a airtight chamber and various chemical filtration systems to keep nitrogen levels high. Portable clean rooms are sometimes used for shipping certain items also. Portable cleanrooms can be used for pharmaceutical, biomedical, bioresearch, microelectronics, hospitals, universities, and also food processing. Some of these portable clean rooms also have a HEPA or ULPA filtration system. You can test the amount of particles with a laser particle tester to verify the work area before starting. When the application of use calls for a positive pressure laminar flow hood check out one of cleanzones portable cleanrooms. So yes I think portable clean rooms are a great solution for shipping and small or startup businesses.Back To Top^

Microns are what people to measure contamination or dust particles in a cleanroom, portable cleanroom, a modular cleanroom, or anywhere particles of dust or contaminates are a problem. The equipment you use to measure this is called a particle counter. This device uses a laser to measure the amount of particles in the air per cubic foot of a portable, modular, or conventional cleanroom. The size of a micron is exactly 1 millionth of a meter. The equipment is used for many situations. Did you know that this dust is produced mainly by our own bodies and our breathing. This equipment will measure the dust particles down to the particles of dust in a cubic foot. Back To Top^

There is one primary difference in HEPA (high efficiency particulate air) and ULPA (ultra low penetration air. First of all if you are asking this question I'm guessing your 'e talking about air filtration for a modular or portable clean room. Well if you are going to need to get to .1 micron of dust you want to use an ULPA system. If you want your clean room equipment to be at least .3 microns of dust particles then you would get the appropriate equipment which would be a HEPA air filtration system.Back To Top^

First of all a modular cleanroom is definitely more cost efficient. The conventional clean room is much more costly because of the labor and schematics and design work. With a modular clean room most of the work is already done for you. A modular cleanroom is also moveable depending on your companies' needs. The modular clean rooms also don't require you to go around and seal of main areas for your equipment. Another great benefit of modular cleanrooms is that you get a quicker return on your investment. Most of these modular cleanrooms come pre-engineered which eliminates costs of an architect or engineer. We use a few modular cleanrooms for biotech stuff. Noise levels can also be a problem lucky for you most modular units are very sound deadening.Back To Top^

I think it all depends on the amount of equipment you use and the size of the clean room you need. And there are all kinds of addons and extras that you may need depending on the class you need to keep you cleanroom within all guidelines and not get any articles contaminated. For instance one of our portable clean rooms has a pass-through. Without this for our cleanroom we would have had to knock a huge hole in our factory wall to create a pass-through. One of our conventional cleanrooms contains eight wet benches. We are currently working on a semiconductor that can transfer 100 gigabits of information per second.Back To Top^

A "Wet Bench" simply put is for wet etching and cleaning of "wafers" and devices. A wafer is a thin slice of semi conducting material such as a silicon crystal, upon which many microcircuits are constructed by doping. Wafers are of utmost importance when fabricating any semiconductor device such as an integrated circuit. Some features  of a wet bench for general use would be a hot plate for heating solutions in beakers. Another feature for a good wet bench would be a constant temperature bath and separate drain for waste disposal. Other types of wet benches could include  a Gallium Arsenide Wet Bench, a Nitride Wet Bench, a Metal Wet Bench, a Nonmetal Wet Bench, and finally a Silicide Wet Bench.Back To Top^

I work for a firm who is currently hiring for an Wet Bench tech. They are asking for 1-3 years in the semiconducter industry. You must obviously be familiar with a wet bench/wet lab operations. Most of the jobs out there also require you to have a good understanding of Clean Room and Modular Clean Room protocol. They are also asking for interpersonal skills simply because we are on a team here in the lab and we all need to collaborate on issues. Another requirement of a job like this is that you can operate and input data correctly. What good is the data we get from our wet bench if it is inputted incorrectly. Since our company mainly works with wafers you need to be skilled in the handling and packaging aspects of all wafers.Back To Top^
