Getting Your PCB Curing Right with Gallium Iodide Lamps

If you’re running a PCB line, you know the drill. You need that photoresist to harden perfectly—not too little, not too much—and you need it to happen fast. That’s where our Gallium iodide lamps come in. We’ve dialed in the wavelength specifically to hit that sweet spot where the resist cures deeply, but your substrate stays safe. The power side of things Here’s the thing: these aren’t your run-of-the-mill mercury lamps. We’ve shifted the emission peak, which basically means the light punches deeper into those thick photoresist layers. You can crank up the power to push your line speeds higher. It’s a great feeling when the boards are flying through. But watch your heat. High-intensity UV gets hot—really hot. If your fans or cooling systems aren’t up to the task, you’re looking at warped boards. Keep an eye on your exhaust, and you’ll be fine. Fitting them into your setup We use high-purity quartz glass because we don’t want the lamp envelope soaking up the UV light it’s supposed to be emitting. We also obsess over where the electrodes sit. Why? Because nobody likes “dark ends.” You want the light to be just as strong at the edges of the tube as it is in the middle. Plus, we can make these in custom lengths. If you’ve already got curing tunnels, these should just slide right in. As long as your ballast voltage matches our specs, you’re good to go. Real-world shop talk For the smaller or mid-sized shops, you don’t need a massive, overpriced rig. You just need something that works. These lamps hit that balance between speed and lifespan. They’re tough, and they can handle the grind of a 24/7 production environment. Just one tip: don’t skip the warm-up cycles. If you just slam them on, you’ll burn out the electrodes way too early. Set your timers right, and these things will keep humming along for thousands of hours. Simple as that.
