Let’s Talk Gallium Iodide Lamps for Your PCB Line
If you’re running a PCB factory, you know the curing and drying stage is where things usually get tricky. That’s where our gallium iodide lamps come in. They work in the short-wave infrared (SWIR) spectrum, which is basically a fancy way of saying they hit the sweet spot for photoresist curing. We’ve tuned these lamps to hit a very specific spectral peak. Why? Because you want the energy to soak deep into the polymers without accidentally frying your copper traces or warping the substrate. The secret is in the heat. Most quartz heaters just throw heat everywhere. But by adding gallium to the arc, we concentrate the energy. It matches the absorption frequency of the resins you’re already using. This means the energy actually goes into the material instead of just heating up the air in the room. It’s fast. Really fast. Just a heads-up: because these lamps pack such a punch, you’ve got to keep an eye on your conveyor speed. If you let the boards linger too long, you’re looking at warped boards and a bad afternoon. Built to actually last There’s nothing worse than a lamp that clouds over after a few weeks of thermal cycling. To stop that from happening, we use high-purity fused quartz. We also spent a lot of time on the electrodes so they don’t sputter. That keeps the inside of the tube clear, meaning the light stays bright and consistent until the lamp actually reaches the end of its life. And don’t worry about a complicated install. These are designed to be drop-in replacements. We offer a few different end-cap options, so they should plug right into your current power supplies. No need to spend your weekend hunting for custom adapters. No middlemen, no nonsense Here is the best part: we handle the whole process. We source the raw gallium and blow the tubes ourselves. Since we aren’t paying a bunch of middlemen to take a cut, we can keep the pricing wholesale without cutting corners on the gas fill or the quartz quality. Plus, because we control the factory, the output doesn’t drift between batches. You won’t have to spend hours recalibrating your ovens every time a tube burns out and you pop in a new one. It just works.
