"Light etching" is a process that involves chemically polishing the surface of glass by a few microns to several tens of microns in order to enhance its strength. When glass is machined, it often develops tiny, invisible scratches known as "microcracks" on its surface, which can lead to a decrease in strength and cause breakage. This technology allows for the removal of microcracks by slightly chemically polishing the glass, thereby improving its strength. [Features] - Increased glass strength - Can be combined with machining - Can enhance strength when performed after mechanical polishing - Makes the glass less prone to breakage when done before strengthening treatment - Compatible with both batch and sheet processing (mass production equipment available) *For more details, please refer to the PDF document or feel free to contact us.

The "Pit Suppression Treatment" can suppress the spread of pits caused by scratches and microcracks. It has a proven track record as a preprocessing step for thinning in LCD panels. Microcracks often occur in machined areas such as cutting surfaces, and even with general strengthening treatments, these areas tend to crack more easily. However, by performing this treatment before the strengthening process, the glass material becomes less prone to cracking. 【Features】 - By simply adding one step to chemical polishing, and with a short processing time, lead times can be reduced compared to mechanical polishing. - The processing time is significantly faster than mechanical polishing, with no risk of microcrack occurrence. - The material becomes less prone to cracking, leading to improved yield. *For more details, please refer to the PDF document or feel free to contact us.

NSC, as a pioneer in chemical thinning of LCD/glass, started with batch chemical polishing and developed a unique technology known as single-sheet chemical polishing. With the single-sheet chemical polishing method, we have successfully established mass production technology for ultra-thin large glass substrates. ■ Main Features - The single-sheet chemical polishing method allows processing of sizes up to 1500mm x 1850mm (G6 size) and thicknesses down to 0.2mm. - Since micro-cracks (very fine scratches that are not visible) do not occur during chemical polishing, high strength can be maintained. It is also possible to address micro-crack issues caused by mechanical processing. - Processing large panels results in higher cost performance per size compared to processing smaller glass substrates. *Differences from batch processing: - No fixtures are required, so there are no fixture marks left behind, and initial fixtures are unnecessary. - It allows ultra-thin processing of large panels exceeding the maximum size of 730mm x 920mm and minimum thickness of 0.25mm in batch processing. - This polishing method is suitable for mass production of the same type, enabling continuous and large-scale processing of large glass substrates. *For more details, please refer to the PDF document or feel free to contact us.
