LDI is an advanced technology that uses a computer-controlled laser beam to directly expose circuit patterns onto a PCB substrate coated with photosensitive material. In this blog. Our new LDI-G2 Series unveils a major leap forward in precision illumination technology, building on the proven performance of our original LDI platform while introducing breakthrough improvements in control, stability, and power delivery. This guide explores how LDI revolutionizes PCB production, from its technical. This revolution begins with a simple line, and its driving force is LDI, or Laser Direct Imaging. The design, created in a CAD program, was first.
