Keeping Your Fab Clean While Turning Up the Heat
If you’re running a Class 100 cleanroom, you already know that air filters only do half the job. The real headache? Outgassing and those tiny, annoying particles that flake off your heating elements. Most standard glass or cheap quartz just can’t handle the heat. Once they hit peak temperature, they start to flake or leak impurities. Not great when you’re working with wafers. That’s why we stick to high-purity synthetic quartz for our IR lamps. It just stays put.
Why the material actually matters
Here’s the thing: it all comes down to what’s inside the quartz envelope. We strip out the trace metals and impurities so you don’t get that “spitting” effect or those microscopic cracks that happen during fast thermal cycling. It means nothing drops onto your substrates. Period. We also use a halogen-filled cycle to keep the filaments alive longer. And that’s a win for everyone—fewer lamp changes mean less downtime and way fewer chances for a human to accidentally bring contamination into the fab.
The nitty-gritty on design
We keep these lamps compact. We use precision-machined end caps to make sure the seal is airtight. If that seal leaks, the halogen gas vanishes and your filament burns out in a heartbeat. We can tweak the wattage and voltage to fit your power rail, but a quick word of caution: high-watt density lamps getintense. Make sure your cooling manifolds are up to the task, otherwise, you’ll see your housing start to warp.
Getting them installed
These are designed as drop-in replacements. You can wire them right into your current controllers without having to tear apart your chassis. But there is a trade-off. High-purity quartz is the cleanest option, but it’s also a bit more brittle than the doped stuff. **Please, for the love of your equipment, don’t touch the tubes with your bare hands.**The oils from your skin create hot spots that will kill the tube prematurely. Grab some lint-free gloves and some IPA wipes, and you’ll be good to go.
