Philoptics developed TGV (Through Glass Via) inspection equipment, it noted on the 30th.
The inspection equipment is a device that verifies whether the TGV process has been properly processed. The work is carried out in the order of ▲camera shooting ▲scanning ▲image generation ▲defect verification.
TGV is the process of drilling tiny holes in glass substrates. In this process, it is necessary to check the processing position, hole shape and size, and whether the glass substrate is damaged.
Philoptics introduced a differentiated method that captures holes at an angle to create a 2.5-dimensional (2.5D) image. In the existing method, where images are shot directly from above, precise image acquisition down to the lower part was limited, but the company explained that this technology resolves these issues.
It also noted that advanced technology has been reflected in the image generation stage.
Philoptics stated, “We have improved data processing and processing speed by incorporating the know-how related to inspection development accumulated over the years,” revealing that it has created an Automated Optical Inspection (AOI) inspection device suitable for mass production.
It also added that it has visualized the hole's defect status to enable quick automatic detection of defects.
Philoptics expects synergy in orders with TGV through this. As TGV is considered essential in the glass substrate process, demand for inspection equipment is expected to be high.
A Philoptics official said, “The company has recorded shipments of glass substrate processing equipment to customers this year, following last year,” adding, “This inspection equipment is expected to generate synergy with TGV equipment.”
