Standard UV lamps just aren&rsquo;t cutting it for high-density photoresist curing. They&rsquo;re too broad. So, we stopped trying to make old tech work and shifted our focus to Gallium Iodide (GaI). We wanted to hit those exact wavelengths that modern circuitry actually needs.</p> <h2 id="the-science-minus-the-textbook">The <a href="https://o-yate.com">science</a>, minus the textbook</h2> <p>Here’s the thing about standard mercury lamps: they throw light everywhere. It&rsquo;s a mess. GaI lamps are different. They put almost all their energy right where it matters—between 300nm and 400nm. That&rsquo;s the sweet spot for most photoresists. The best part? Because we aren&rsquo;t wasting energy on a broad spectrum, you don&rsquo;t get that nasty IR heat soaking into your boards.**No more warping.**Just faster curing and cleaner results.</p>
