Making Gallium Iodide UV Systems Actually Smart

If you’ve spent any time in a PCB factory, you know the drill with Gallium Iodide lamps. They’re great for high-precision photoresist curing because they hit those specific UV wavelengths you need. But for a long time, these things have basically just been “dumb” heat sources. We’re changing that. We’re turning them into networked assets by adding remote energy monitoring.

Why Gallium Iodide Matters (And Where it Fails)

Here is the deal: Gallium iodide emitters are way more precise than your standard mercury lamps. They give you a much tighter cure profile. That’s a huge win because it stops the resist from over-curing, which is usually why you end up with peeling or brittle traces. But there’s a catch. These lamps are incredibly finicky when it comes to voltage. If your power supply drifts even a little, your consistency goes right out the window.
