Daeduck Electronics News

Nvidia is cutting SOCAMM2 memory capacity from 192GB to 96GB per module (LPDDR5X stack 4-high→2-high) to work around LPDDR shortages for its Vera CPU-based AI servers. Module and MCP substrate counts stay the same (8 modules + 32 substrates per Vera CPU), so Korean substrate suppliers (Simmtech, Daeduck Electronics, Korea Circuit) are net winners as more servers can be built off the same LPDDR pool. Memory players (Samsung, SK Hynix) read the cut as proof LPDDR demand from AI servers + RTX Spark AI PCs is outrunning supply, not weakening.

Why it matters: TheElec scoop on a concrete Nvidia spec change with clearly named beneficiaries — Korean substrate makers gain unit volume while LPDDR shortage signal is positive for memory names.

Chinese players are speeding up development of semiconductor glass substrates — a next-gen advanced packaging material seen as key for AI/HPC chips — and aiming to challenge Korea in the race to mass production. The move intensifies competition for Samsung, SK Hynix and Korean substrate suppliers (SKC/Absolics, LG Innotek, Daeduck) who have been positioning glass substrates as a strategic 2026-2027 opportunity.

Why it matters: Glass substrate is a strategic medium-term packaging theme for Korean semi value chain, but this is competitive/industry news rather than a near-term earnings or policy catalyst.

Daeduck Electronics' FC-BGA revenue jumped 62% in two quarters (Q3'25 KRW48.7B → Q4'25 KRW69.9B → Q1'26 KRW79.0B), with the segment turning profitable in Q4'25 as AI server demand spills over from leaders (Ibiden, Unimicron, Shinko, Nan Ya PCB, Samsung Electro-Mechanics) to Korean second-tier players. Daeduck has resumed the previously paused KRW270B capex at its Ansan B2 plant, focused on equipment additions for mid-tier server controller/automotive FC-BGA — a clear positive read-through to Korea Circuit as well.

Why it matters: TheElec scoop with concrete quarterly revenue figures, profitability inflection, and confirmed capex resumption at a tracked KR name — directly actionable for FC-BGA supply-chain positioning.

CNBC reports that Chinese-made printed circuit boards embedded under AI accelerators in U.S. data centers are drawing scrutiny from national security officials over potential backdoors and supply-chain risks. The story could accelerate a push to qualify non-China PCB and substrate suppliers for AI server boards, benefiting Korean and Taiwanese substrate makers while pressuring hyperscaler BOMs.

Why it matters: Sector-wide supply-chain theme that could shift AI server PCB/substrate sourcing toward Korean and Taiwanese vendors, but no specific policy action or company event is announced.

TheElec reports Nvidia has placed no orders or development requests for the GDDR7 memory (128GB / 8x16GB) or substrates planned for the Rubin CPX inference GPU originally slated for 2H 2026, and dropped the chip from its GTC 2026 roadmap. Memory and substrate industry sources view the project as effectively cancelled, killing a key expected GDDR7 demand catalyst for SK Hynix and Samsung (currently GDDR7 is confined to RTX 5090/5080) and substrate suppliers; Nvidia appears to be pivoting inference strategy toward Groq's LPU following its $20B licensing deal.

Why it matters: TheElec supply-chain scoop confirming zero GDDR7/substrate orders from Nvidia removes a major expected demand catalyst for Korean memory makers and substrate suppliers, and signals a strategic pivot to Groq LPU for inference.

Daeduck Electronics is simultaneously expanding FC-CSP, FC-BGA and MLB capacity to ride AI server demand, with a newly disclosed KRW 213B FC-CSP plant at the Siheung B1 center (lifting FC-CSP capacity >30%), resumed FC-BGA investment at the Ansan B2 center (cumulative FC-BGA spend ~KRW 540B through 2027), and a near-complete MLB expansion in Ansan roughly doubling MLB capacity. Q1 revenue rose 60.8% YoY to KRW 346.3B with operating profit swinging to KRW 51.3B as AI-server/network-gear MLB and FC-BGA sales accelerated, and management sees the P&L entering an improvement phase as initial depreciation burden eases.

Why it matters: Direct, ticker-specific capex disclosure with quantified capacity uplift and a clear Q1 earnings inflection for Daeduck Electronics, a key KR AI substrate name.

South Korean policymakers are reportedly discussing a 'national dividend' mechanism that would redistribute excess profits from domestic semiconductor companies to the broader public. The proposal, likened to a socialist profit-sharing scheme, would primarily target large chip conglomerates such as Samsung Electronics and SK Hynix. If advanced, this could introduce a new fiscal overhang for Korean memory and foundry names and weigh on shareholder return expectations.

Why it matters: A domestic profit-redistribution policy targeting Korean semiconductor companies would directly affect Samsung and SK Hynix earnings and capital return capacity, but this appears to be early-stage commentary rather than a concrete legislative proposal.
