Five Key Considerations

To acquire an accurate quote, there are important pieces of information that any cleanroom supplier will need to be aware of. The answer to these questions will make up the brief to the supplier and ultimately the backbone of an order.

1. Cleanliness/classification level – Classification needs are usually product driven through official manufacturing guidelines. Customers will have to research their specific manufacturing cleanliness necessities to develop their user requirement specification (occasionally abbreviated to URS).

2. Size of room required – A cleanroom supplier can help customers to answer this question but they will need to be aware of the dimensions of any large pieces of equipment, this can mainly effect ceiling heights, how many people will be present in the cleanroom at any one time, and the volume of product/material placed inside the room.

3. Design elements – Practical information to pass onto a cleanroom supplier are: how do customers get their material in/out of the cleanroom and how do people interact with process utilities, process equipment layout, the product/ product flow, personnel flow, electrical requirements, and maintenance access.

4. Additional controls – If humidity and temperature are vital to a process, customers have to define it. Be aware that regulating humidity and temperature will significantly increase both their running costs and purchase price.

5. Special requirements – Process specific requirements have to be very detailed. For instance, BMS control, negative pressure, ESD, molecular, harsh cleaning solutions, electrostatic and magnetic sensitivities.

Conclusion

The answers customers provide to these questions can have a great effect on both the preliminary purchase price and the long-term facility operational costs, so it is vital to be as accurate as possible.

Clean Environments is unique because not only it designs and constructs cleanroom systems but critically, as part of Moorfield Nanotechnology, also operates as cleanroom users. Clean Environments will highlight any parts of the specification which will increase customer’s running costs or hinder their process, offering solutions.
