Gallium Iodide Lamp for PCB Factories: Built for Zero-Contamination Work
We built this Gallium iodide lamp for one reason: to give PCB factories a heating and curing tool that’s truly clean—and truly reliable. This isn’t some general-purpose UV lamp. It’s purpose-built for the high-precision world of PCB manufacturing, where contamination isn’t an option and uptime can’t be negotiated.
Power, voltage, and size—made for the shop floor
Here’s the thing: this lamp runs at 400V, not standard mains voltage, because it needs to deliver stable, high-energy output day after day. At 2500W, it throws down the heat density required to cure solder mask and coatings fast—even on dense boards. And it does all that in a compact footprint: 300mm long, 10mm diameter. That means it slips into tight chambers and retrofits into existing equipment without forcing a full redesign. Fast results. Small package. But yes, it comes with a trade-off. All that power packed into a 300mm tube means serious heat. So you need machine cooling that’s up to the job—otherwise chamber temperature can drift. Plan the cooling right, and the lamp keeps performing with repeatable results.
Materials and design: clean light, tough build, easy hookup
Inside, we use a halogen cycle inside a high-purity quartz envelope. That’s what helps keep the bulb wall clean and keeps UV output steady over time. The gallium iodide fill shifts the spectral output toward the UV range you need for curing—while cutting down on ozone. And the quartz doesn’t blink at thermal shock or harsh process chemicals. It just handles it. Then there’s the R7s connector. Practical choice. Two-point contact, wired up quickly in-line, and built to stand up to high temperatures. It’s a solid, low-maintenance connection—and it drops right into many standard holders, so changeover stays fast.
What this means for you on the PCB line
On the shop floor, this lamp is the go-to for curing, drying, and thermal processing steps where even tiny residues or particles can wreck yields. The materials are chosen for tough, all-environment use, and the long-life design means fewer surprise burnouts. So what does that feel like? Fewer stoppages. Process parameters that stay stable. Less time spent swapping lamps and troubleshooting. This lamp is built to run hard, day after day. Just make sure your cooling is properly matched to its power density. Give it the heat management it needs, and it’ll keep your line moving without drama.
