[Philoptics] SKC's First MWC Appearance and Glass Substrate Display
A short memo on SKC's MWC2025 glass-substrate news from the perspective of Philoptics, Chemtronics, and Avaco
0. Bottom line first
SKC displaying an actual glass substrate at MWC2025 looks like another sign that glass substrates are becoming a more concrete future. Still, mass-production yield must be verified, and for Philoptics I am watching for proper technical support before considering re-entry.
Official fact: According to the linked article, SKC participated in MWC2025 in Barcelona from March 3 to 6, 2025 local time and displayed an actual glass substrate inside SK Telecom's exhibition area. News link: https://n.news.naver.com/article/011/0004456593
Interpretation: Because of heat issues in high-performance packaging, I think the direction toward glass substrates is largely set. The key question is yield in mass production, so stock charts and support levels still matter before adding exposure.
1. Investment watchpoints
I read this news as a signal of the approaching future. Glass substrates seem directionally right because of heat issues, but I still do not know how mass-production yield will look. So I am watching Philoptics, Chemtronics, and Avaco while waiting for proper support on the chart.
Equipment and process exposure
I previously recorded an exit, but after the high-volume bearish candle I am watching whether support forms.
Glass-substrate value chain
Named as another company to track within the glass-substrate theme.
Process-equipment comparison
A name connected to the earlier Schmid Group and glass-substrate process research.
