Monitoring Solutions for Semiconductor Subfabs

A semiconductor transistor is a part with specific electronic properties that allow it to serve as a component in microchips and modern electronics like phones, laptops, and more. As these components are small and require precise manufacturing methods, there are facilities dedicated to their manufacture. 

These facilities consist of several levels including air handlers and scrubbers for exhaust, HEPA room, fab cleanroom, and subfab areas. The control of pressure, flow, and temperature within the facility is essential. 

Semiconductor subfabs are located directly below the cleanroom. Here you will find an array of ancillary equipment, such as vacuum pumps, abatement systems, chillers, gas cabinets, and other equipment to keep process tools functioning efficiently. The equipment within the subfab is interconnected with the tools found within the fab cleanroom itself; these separate but connected areas work together to make sure the facility runs smoothly.  Continue reading “Monitoring Solutions for Semiconductor Subfabs”

Visit Us at the Process Heating & Cooling Show!

It’s here! The Process Heating & Cooling Show kicks off today at the Donald E. Stephens Convention Center in Rosemont, IL. Be sure to stop by booth 313 to meet the Dwyer Instruments and Omega Engineering teams, and learn how we can help with your next process automation project. 

We will have a flow bench at the booth where you can see our products in action including the latest temperature, pressure, flow, and industrial internet of things (IIoT) technologies. Continue reading “Visit Us at the Process Heating & Cooling Show!”

The Importance of Water in Concrete Mixing

Concrete is used all around us as foundation for buildings and exterior surfaces, parking lots, sidewalks, countertops, and more. Although walking or riding a car on concrete is a daily occurrence, it’s easy to overlook the basic elements that go into this essential of modern living. 

Concrete is made of a few basic components:

  • Sand and/or aggregate
  • Cement, comprised of limestone and clay that have been crushed and mixed into a fine powder solution
  • Water

Of these components, the ratio of water to cement is particularly important. Continue reading “The Importance of Water in Concrete Mixing”
