Heat is one of the fastest ways to kill crystal stability in a thin film deposition process.

That’s why cooling design matters.

Shown here:

▪️ Quartz Crystal Sensor with larger-diameter cooling tubes for improved thermal control

▪️ Crystal Oscillator

▪️ In-vacuum microdot cable

▪️ 6 MHz quartz crystals

When you’re monitoring deposition rate in real time, stability isn’t optional.
Temperature drift = frequency drift = bad data.

Our larger cooling tube configuration helps customers running higher power processes maintain consistent crystal performance and extend crystal life.

In thin film deposition, small details make a measurable difference.

💡 Employee Spotlight: Jim

If you’ve ever worked with McVac, there’s a good chance Jim had a hand in your project — literally.

Jim has been with McVac for many years (long before some of us were even tall enough to see over the workbench). He’s the leader out in our machine shop and the go-to person when it comes to our custom machining and welding work. There isn’t much that comes through our doors that Jim hasn’t helped build or improve.

His experience and dedication are a big reason we feel confident telling customers we can get a job out the door quickly — and done right. Whether it’s precision machining, a rush order, or a complex custom assembly, Jim’s the steady hand and sharp mind that keeps things running smoothly.

Beyond the technical side, he’s also one of the best examples of McVac’s core values — hard work, pride in craftsmanship, and teamwork.

We’re lucky to have him on our team. 👏

💡 Customer Need → McVac Solution

When customers asked for better cooling in demanding deposition processes, we engineered a solution.

Our large-body Crystal Sensor, shown here on KF 40 fl**ges, delivers improved cooling capacity and reliable performance where it’s needed most.

Since 1989, McVac has been designing thin film coating tools built around customer requirements — quick, precise, and trusted worldwide.

Every project comes with unique challenges. In this case, a customer needed a way to mount a quartz crystal sensor where standard solutions just wouldn’t fit.

Working closely with the customer, our team designed and manufactured a custom nut-and-fl**ge mounting system that allows the sensor to be installed securely without deformation—making both installation and future maintenance straightforward.

That's one of the things we do best - turning complex problems into practical solutions for our customers.
