Introduction
When you’re building PCBs, the solder mask step is the point of no return. Get it wrong, and the whole board is a loss. That’s why we built our UV lamps for this exact moment. For the world of fine lines and hair-thin clearances, where there’s absolutely no room for error. We designed these to deliver a hard, focused blast of UV light—the kind that fully cures modern solder mask ink without leaving a trace of adhesion failure behind. It’s about matching the intensity to the job, and keeping pace with a production line that never slows down.
Let’s Talk Power, Voltage, and Size
Here’s the quick rundown: our standard unit runs at 400V and 2500W, with a 300mm tube. That power density isn’t random. It’s all about focus. By packing the UV energy into a tight space, the lamp can sit close to the board without scattering energy where it isn’t needed. And the 300mm length? It’s a perfect fit for standard tooling and lane widths. So you can swap it in as a straight replacement without tearing your line apart. The 400V supply is there for one reason: stability. Even when the factory voltage dips and spikes, the arc stays steady. That means the light output stays consistent, shift after shift.
Built to Last: The Materials That Matter
Inside, the core is a high-purity quartz envelope. It handles the shock of rapid heating and cooling, and it stays crystal-clear for UV light, even after thousands of run hours. We also apply a special coating to even out the output and kill hot spots. The payoff? No more uneven curing along the length of the lamp. For the connections, we use an R7s connector. It locks in with a solid mechanical fit and keeps the contacts perfectly aligned. So even with factory vibration and frequent lamp swaps, it stays put. This isn’t a delicate piece of equipment. It’s built to survive the factory floor—the real one, not the one on paper.
What It Does for You: Solder Mask That Actually Sticks
On those fine-pitch traces, solder mask adhesion fails when the ink doesn’t fully cure in the tight gaps. Our lamp blasts through those spaces quickly with high-intensity UV, hitting the right dose without overheating the laminate. The result is a cure you can count on, every single time. It holds up through solder float tests and the harshest cleaning processes. Now, a heads-up: that 2500W density is powerful, so it needs proper machine cooling and reflector alignment. Make sure you have airflow and thermal management in place. That’s how you keep the work area stable and the process smooth.
