Stop Letting Your Heaters Ruin Your Vacuum

If you’re running a Class 100 cleanroom, you already know the drill. You’ve got the filters and the protocols locked down, but there’s one sneaky problem that still trips people up: the heating elements. Most IR lamps are fine for basic work, but once they hit high temps, they start shedding micro-particles or outgassing. In a vacuum, that’s a nightmare. There’s no air to carry that junk away. Whatever flakes off the heater goes straight onto your substrate. That’s why we use high-purity synthetic quartz. **The secret is in the silica.**We use a version with very low hydroxyl (OH) content. Why? Because it keeps the tube from softening when things get hot and stops impurities from leaching into your vacuum. No residue means no “ghosting” or weird spots on your wafers. It just stays clean. But there’s a catch when you’re working in a vacuum: you lose convective cooling. You can’t rely on air to move the heat around. Our lamps are designed to push energy directly into the target through radiation. We also beefed up the seals at the electrode junctions to make sure nothing leaks. One quick tip: watch your wattage. If you cram too many watts into a tiny space without a solid heat sink on your chamber walls, you’re going to bake your vacuum seals. And once those fail, you’re in for a long day. As for getting these into your system, we’ve kept it simple. We offer a few different connector options so they just slide right in. Whether you’re building a custom array from scratch or just swapping out a dead tube, the fit is tight and secure. Just keep an eye on your voltage stability. Spikes can kill a filament faster than you’d think. Stick to the rated voltage, and your lamps will actually last.
