The film-removal process without using an abrading agent will generate residues of removed films only, thus no cleaning equipment is required. |
| » |
This method significantly reduces particulate emissions, allowing the installation within the clean room. |
| » |
The processing time is drastically shortened. |

Comparison with sandblasting : |
| |
Edge isolation system |
Sandblasting + washing |
| Size |
Saves space |
Occupies considerable space |
| Equipment must be shielded to contain dust |
| Washing |
Removes residue using dry cleaners or suchlike |
Washing process is required |
| Impact on film |
No adverse affect on other areas |
Scattering of abrading agent may damage the film surface, thus reducing module output |
| Others |
Very small amount of residue remains on the glass substrate, and post-processing is easy. |
Even after being washed, some abrading agent may remain on the glass surface, causing problems during the lamination process |
