Getting Your PCB Curing Right with Gallium Iodide Lamps

If you’re working with PCB photoresists, you know that getting the cure just right is a bit of an art. That’s where our gallium iodide lamps come in. We’ve tuned these specifically to hit the absorption bands of the photo-initiators in your dry-film or liquid resists. Basically, they provide the exact kind of light your resist needs to harden properly.

The secret is in the spectrum

Most standard UV lamps just don’t cut it here. Our emitters shift the peak output toward longer UV wavelengths, which is a big deal. Why? Because it lets the light actually sink deeper into the resist layer. You end up with a cure that’s consistent from the top all the way to the bottom. No soft spots. We’ve spent a lot of time calibrating the wattage and voltage so your irradiance stays steady across the whole panel. But a word of warning:**don’t just crank them to max.**If you do, the heat can actually warp your thinner substrates. You’ve got to find that sweet spot between your conveyor speed and the lamp’s intensity so you don’t bake your boards.

Getting Your PCB Curing Right with Gallium Iodide Lamps

If you’ve ever dealt with a batch of scrapped boards because the photoresist didn’t cure properly, you know how frustrating it is. It’s a nightmare. That’s exactly why we build our gallium iodide lamps. They hit those specific UV wavelengths you need to get the job done right, every single time, even when your assembly line is screaming along at full speed.

The Technical Stuff (Simplified)

Here’s the thing about these lamps: they’re designed to target the curing agents in your photoresists specifically. If you need to speed up your conveyor, you just need more “punch”—which means higher wattage. More photons hitting the board means you can move faster without worrying about under-curing. But a word of caution:**watch your voltage.**Make sure your lamp and ballast are a perfect match. If you push too much power through the tube, you’ll fry the electrodes, and you’ll be replacing lamps way sooner than you should.

What This Lamp is Really Built For

Here’s the thing: we built this UV gallium lamp to be a straight-up workhorse. It’s all about packing a serious punch into a focused beam. For PCB exposure, we’re talking about a 400V input that pushes 2500W of power into a 300mm tube. And no, that power isn’t just for show. It’s what creates the intense shortwave UV you need to fully set the photoresist on a circuit board. The 300mm length? That was a deliberate choice. It keeps the footprint small, so you can drop it right in and swap it out in your existing unit. No messy redesigns. Just swap and go.
