AI substrates need more CCL layers
AI GPUs and CPUs are making substrate packages larger and thicker, requiring more FCBGA, MLB layers, and CCL; domestic substrate utilization is near full, capacity expansions are underway, and customer discussions already extend to 2030, so the PCB/CCL supply chain can keep rising even if memory leaders pause.

Samsung Electro-Mechanics has visible substrate demand
Samsung Electro-Mechanics is a substrate supplier with utilization near full and customer discussions already extending to 2030 volumes, implying it needs capacity expansion to meet AI substrate demand.

Isu Petasys benefits from thicker MLB
Isu Petasys is a direct MLB beneficiary; AI boards are moving from 18 layers toward 40 or more, making substrates thicker and larger, and the stock has already shown sharp upside as this structural demand grows.

Daeduck gains from thicker MLB demand
Daeduck Electronics also produces MLB and should benefit from the same thicker-board cycle; the speaker distinguishes this upcycle from the 2021-2022 glut because AI substrate area and layer counts are structurally increasing.

Copper foil demand lifts Lotte Energy
Lotte Energy Materials should benefit as CCL demand lifts copper foil demand, adding to its secondary-battery copper foil exposure, and its shares have already performed strongly on this theme.

Doosan is Nvidia's sole CCL supplier
Doosan's Electronic BG is the key CCL name: its CCL won Nvidia's Blackwell qualification while Taiwan EMC failed, making Doosan the sole supplier, and its DK/DF signal-loss metrics are better than peers; EMC may need more than a year to re-qualify, so Doosan should remain the sole CCL supplier through Rubin in 2027, with additional TPU and domestic substrate customers, while Doosan's holding-company value is supported by Doosan Enerbility and Doosan Tesna.

Pharmicell supplies Doosan exclusively, capacity doubles
Pharmicell is effectively a semiconductor-materials supplier: it exclusively supplies resin and curing agents to Doosan's Electronic BG after 10 years of joint development, about 60-70% of sales come from Doosan, operating margin is above 30%, and a 2026 expansion should roughly double resin/curing-agent capacity, though the small cap and volatility argue against rushing in.

Shipbuilders gain data-center engine demand
Shipbuilding is an attractive sector because newbuilding prices keep rising, LNG orders are still expected, and medium-speed engines for data centers are creating a new demand layer that could re-rate shipbuilders as AI infrastructure plays.

HD Hyundai Heavy wins data-center engine orders
HD Hyundai Heavy Industries is the preferred shipbuilding pick: HIMSEN's 20MW medium-speed engines received a 33-unit data-center order, the company reached 43% of its annual commercial-ship order target by March, additional engine orders are likely, and 2028 engine capacity is already about 30% filled, so tangible orders support both earnings and valuation re-rating.

Samsung Heavy benefits from LNG orders
Samsung Heavy Industries remains attractive on its core LNG shipbuilding business, as Middle East supply disruptions are strengthening the case for more LNG supply and LNG carrier orders, though the speaker now prefers HD Hyundai Heavy Industries for valuation re-rating.

Marine Solution benefits from engine servicing
HD Hyundai Marine Solution is a later-cycle engine aftermarket beneficiary: data-center engines will run much longer, shortening maintenance cycles and increasing service demand at higher margins than ship repair, but concrete agreements are not yet in place and the meaningful service cycle starts around 2030, so investors should focus on HD Hyundai Heavy Industries first and watch Marine Solution later.
