LDI uses a UV laser with a DMD or galvanometer optical system to directly scan-expose circuit patterns onto photosensitive laminates — replacing mask and photoplotting entirely. Patterns are data-driven, so changeovers are instant and accuracy and consistency improve markedly.
- Alignment down to ~0.1μm for higher fine-line yield
- No mask waste — extremely low cost for small/frequent batches
- Covers inner/outer layers, solder mask, legend and more
