There are several criteria to consider when selecting equipment for your cleanroom. Making the best choice doesn’t need to difficult, but it does need to be well thought out. Here are some guidelines for you and your coworkers to follow when making this decision.
Compliance requirements: Your first concern with new equipment is that it is compliant with your specific cleanroom. Clear communication between you and the supplier is the key to choosing the right equipment for your cleanroom. Tell the supplier in writing your:
Type of industry
Any ESD or AMC concern
The supplier or manufacturer should send back clear specifications including:
Everything the proposal entails
Standard product features
ESD or AMC compliance
Other available features
Once you have this, review everything with the appropriate coworker(s) to ensure the specifications match your needs.

Employees who work in labs that handle glassware know all too well the frequency of injuries that happen in this environment. Minor cuts are most often the result of an accident, but more serious injuries do occur. Flying glass, exposure to chemicals, and fires are all realistic scenarios that can inflict serious harm.
According to ALN Magazine’s online article, “Twelve Tips for Working Safely with Laboratory Glassware,” by Vince McLeod, CIH: cuts, punctures, and scrapes alone accounted for nearly a quarter of workers’ compensation claims between 2006 and 2008. The cost of these claims totaled over $100,000.
For the sake of safety, time, resources, and cost, be sure you’re following these 12 tips for handling glassware:
Choose the right Personal Protective Equipment (PPE). Working in a cleanroom, you may already have your arms, legs, and hands covered. Be sure to also wear … Read More »
Cleaning a cleanroom sounds redundant, but routine maintenance and cleaning are a big part of what keeps these environments compliant. Of course, cleaning procedures will differ according to required cleanliness levels, processes occurring in the cleanroom, and the individual company. However, experts agree that there are some universal steps to follow.
1. Establish Environmental Monitoring (EM) and identify viable and/or nonviable contaminates.
2. Using the results from the EM program, select cleaning chemicals and disinfectants. Choose appropriate cleaning materials for your specific class of cleanroom. This includes everything from buckets to vacuums. Remember that ESD materials are available for those environments concerned with static discharge. Test that all solvents and materials perform as expected.
3. Establish Standard Operational Procedures. The Institute of Environmental Sciences and Technology (IEST) is a great resource for protocol. Create your SOP based on your needs. You want … Read More »
As you may have noticed, we depend on more and more electrical and electronic equipment every year. We rely on this equipment for everything from safety to entertainment. Almost all of this equipment relies on printed circuit boards (PCBs). Manufacturing PCBs is a very delicate process. For some high density circuit boards, humidity or contamination can cause yield or field failures. Therefore, the process of creating a PCB must be carried out in a cleanroom.
The class of cleanroom required – or the number and size of particles allowed per cubic meter – differs for all materials. You need to know what the specifications are for the product and materials you are manufacturing. PCBs are typically manufactured in ISO 7 or 8 cleanrooms. Flexible printed circuits production is an imaging-intensive operation. Imaging processes may be done in an … Read More »
