Replacing Gallium Iodide: A Direct Drop-In Upgrade
We built this UV lamp system to be a straight swap for gallium iodide lamps—the kind you use when dicing semiconductor wafers. The whole point is simple: strip that UV adhesive film off the wafer backing without overheating the wafer itself. Gallium iodide lamps are getting tough to find and even tougher to keep running. So we gave you a modern, stable light source that’s a true drop-in replacement. No hassle. No rework. Just a better way to get the job done.
Power, Voltage, and Fit: The Practical Details
Here’s the heart of it: a high-intensity, shortwave UV lamp, engineered to fit the electrical footprint of your existing setup. It runs on 400V input, because that’s what it takes to deliver the power density you need for fast adhesive release. That voltage pushes the quartz arc tube to produce serious output—so your machine’s power supply and cooling system do need to be rated for it. On the physical side, the dimensions are standardized. It drops right into the fixtures you already have. Plug-and-play. No rewiring. No redesigning tooling.
Why the Coating and Connector Actually Matter
The quartz envelope handles the heat, sure. But the real difference is the internal coating. We tuned the spectral output to the exact wavelength the UV film needs. That precision keeps unwanted heat out and makes sure the adhesive releases exactly where you want it. And that R7s connector? Not an afterthought. It locks the lamp in place, keeps the electrical contact solid, and holds the lamp aligned inside the reflector. In production, that stability means fewer micro-vibrations—and consistent output over the life of the tube.
In Action: Speed and Control, Without the Guesswork
In wafer dicing, the UV film holds the wafer steady while you cut. After cutting, the film has to release instantly—clean, residue-free. Our lamp delivers the precise wavelength that breaks that bond cleanly. The result is a faster, cleaner strip cycle, and a process that feels more repeatable. You get the speed you need without risking damage to the wafer. The kind of control that keeps the line moving—steady, predictable, and under your hands.
