1.Product Introduction

 

The SDI series is an industry-leading photovoltaic direct imaging solution for high-precision patterning processes of photovoltaic solar cells.
The system utilizes DMD technology, and through its high-precision data resolution capability, with resolution accuracy better than 15μm and excellent line width consistency and edge roughness, it ensures efficiency gains while reducing overall operating costs.

 

2.Product Feature

 

  • Direct writing lithography without mask, non-contact exposure process;
  • 405nm semiconductor laser, low exposure dose without substrate laser damage;
  • Back to back dual track M10/G12 half chip ≥ 10000wph;
  • Graphics easy to edit, substrate size for 166~210 whole as well as half cells;
  • Alignment accuracy: gripping edge alignment ± 0.05mm, Mark high-precision alignment of ± 10μm;
  • Applicable to different photosensitive materials, resolution accuracy better than 15μm, line width tolerance ±10%;
  • High-precision environmental control system, good stability;
  • Windows-based system, user interface for easy operation.
