let’s talk about timelines for a sec:
- memory companies are signing multi-year LTAs.
- neoclouds are signing 15-year leases.
- hyperscalers are building 41 GW through 2030.
- Google literally issued a 100-year bond.
the bottlenecks (GPU, CPU, memory, photonics, GaN/SiC, etc) will continue and imo only get worse.
retail tends to get overly emotional over a few red days and decide the AI trade is over.
Jensen will clear the air tonight and we can all go back to being normal.

Feels like glass substrate timelines got pushed back at least another quarter.
- "Samsung Electro-Mechanics Delays Semiconductor Glass Substrate Investment" due to a bottleneck in customer reliability evaluations of prototypes.
At its recent second-quarter earnings presentation, less than a month later, the company revised the start of operations to 2028.
- "SKC Reportedly Pushes Glass Substrate Mass Production to 2027, Targets Final Validation by Year-end" (Trendforce), earlier last month.
TLDR:
- SKC Absolics H2 2026 -> H1 2027
- Samsung H2 2027 -> H1 2028
Not everything is always good news with timeline shifts, but glass core substrate shifts do feel imminent.
Volume ramp for some players eg. $LPK / Philoptics (161580) / E&R (8027) likely track these mass production timelines.

Some updates on bottleneck timelines:
- ABF substrates: 1 year
/ eg. Ajinomoto (2802) for ABF film, Ibiden, Unimicron, Nan Ya PCB, etc make the substrates
- HDI Boards: Over 6 months
/ Victory Giant (300476), Zhen Ding (4958), Unimicron, Compeq (2313), Meiko (6787)
- Multilayer boards: ~6 months
/ Victory Giant, WUS (002463), $TTMI, Gold Circuit Electronics (2368),
- CCL: Over 6 months (severe shortages of materials)
/ Elite Material (2383), Shengyi (600183), TUC (6274), ITEQ (6213), Nan Ya Plastics (1303), Resonac (4004)
Mitsui Kinzoku (5706) / HVLP copper foil. Nittobo / glass fiber/cloth
- MLCCs, chip resistors, tantalum capacitors, aluminum electrolytic capacitors: 15-20 weeks to 1 year+
MLCC: Murata (6981), Samsung Electro-Mechanics, TDK (6762), Taiyo Yuden (6976), Yageo (2327), Walsin (2492)
Chip Resistors: Yageo, Walsin, KOA (6999), Rohm (6963) and $VSH
Tantalum capacitors: Kyocera/AVX, Yageo/KEMET, $VSH again
Aluminum electrolytic capacitors: Nippon Chemi-Con (6997) Nichicon (6996) | Timelines sourced from Digitimes, did the honors of adding in related companies.
But it's slightly more nuanced since MLCCs and others mix. in commodity types vs. AI DCs.
Regardless, just some helpful mapping.
