UV gallium lamp for PCB exposure

Look, the UV lamp market is packed. Everyone’s waving around spec sheets that all start to sound the same. But when you’re exposing PCBs, there’s no room for bluster. The truth is brutal: if the lamp doesn’t meet compliance, the whole line stops. Period. So we built our UV gallium lamps to cut through that noise. They’re made for one thing—reliable, repeatable exposure that keeps your production moving, and meets the rules for selling your boards anywhere in the world. Let’s get into the guts of it. These lamps are built for the real grind of a PCB shop floor. We tune the output to the gallium spectrum, so you get the exact wavelengths you need for rock-solid curing. That power is matched to a 400V high-voltage input. Why does that matter? Because high voltage keeps the arc temperature steady, which means your UV output stays consistent, day after day, for the life of the lamp. And physically, it’s a straight swap. The length and diameter are standard, so it drops right into your existing fixtures. No messing with the machine chassis. Just in, and you’re good to go. The details that actually make a difference. The quartz envelope isn’t just any glass. We chose it for how cleanly it transmits UV and how it handles heat without blinking. Inside, the gallium amalgam locks in the spectral output, so you don’t get the wavelength drift that plagues cheaper mercury lamps. Then there’s the R7s connector. It’s a practical choice that handles the high current and heat without loosening up. That means when it’s time to swap the lamp, it’s a quick, simple job on the floor. No fuss. What this means for your day-to-day work. On the line, this setup means faster exposure times and fewer headaches. The consistent output cuts down on under-curing and over-exposure defects. Now, the trade-off is heat. A 400V system puts out a lot of it, so your machine’s cooling has to be up to the task. That’s where CE certification isn’t just paperwork. It confirms the lamp meets safety and EMC standards, which protects your equipment and keeps your export shipments moving. For us, that certification isn’t just a sticker. It’s the baseline. It’s about building a lamp you can wire up, trust, and forget about—so you can get back to work.
