IC substrates are Schmid's more relevant growth driver today because demand is already high and rising. Schmid customers Ibiden and Unimicron are expanding capacity with NVIDIA support; higher order intake supports the prospect of more equipment orders. Its balance sheet has improved, and the risk/reward looks attractive at current levels despite volatility. Glass substrates may take another one to two years to matter commercially. This is a personal assessment, not a buy recommendation. x.com  … Show more

LPKF Laser is a bottleneck supplier for glass substrates, the next-generation AI packaging material Intel, Samsung and TSMC are piloting. Glass cracks when drilled, and LPKF's LIDE is one of very few processes that structure glass at production scale without cracking, so no glass ecosystem gets built without a tool like it. Management says the question is now when the ramp begins, not whether. Besi trades at 77x EBITDA on advanced packaging; upstream names trade at fractions of that. x.com 

LPKF Laser & Electronics and Schmid Group shares should deflate fast because glass-core substrates are not expected to be adopted until 2030, per @AtlasShrug1 citing @pequityresearch, a long wait for any ramp. x.com 

LPKF's glass-substrate thesis has barely started even after the stock's run. Its LIDE process drills defect-free through-glass vias at production speed with aspect ratios up to 1:50, and glass is the only material that solves CTE mismatch, dielectric loss and warpage at once, where silicon interposers cannot scale. Over 80% of major players chose LPKF equipment for validation, a de facto standard; first production orders came in Q1 2026, and the 2027 mass-production ramp hits the P&L hard. x.com 

LPKF Laser & Electronics, the leader in through-glass vias, has meaningful upside as Intel's EMIB and glass-substrate manufacturing pick up, though it is speculative for now. Its technology is good, but it faces competitors such as DR Laser and Corning. Sizing up needs follow-through from Intel and the rest of the industry, clarity on how supply chains shape out, and a more convincing ramp and go-to-market. x.com 

LPKF faces mostly lumpy, cancelable pilot-line revenue until 2029, while the market already prices in much of its glass substrate option. Volume demand for its glass equipment hinges on TSMC and NVIDIA choosing glass for CoPoS panel packaging; that wave lands around 2028-29 and could slip to end-2030 on warpage and yield issues. Absolics' and Semco's 2027 plans are qualification. The real signals are TSMC's CoPoS tool-vendor selection and an LPKF order above EUR 10M naming a Tier-1 customer. … Show more

Glass fiber cloth is a huge bottleneck for GPUs, ASICs and 800G/1.6T switches, and demand is shifting to alternatives as Nittobo, with 90% of T-glass and 70% of NER-glass, lacks capacity until mid-2027. Taiwan Glass is among the strongest near-term AI plays, with low-CTE output ramped in Q1 2026 and Nvidia/AMD certification. Fulltech is moving to T-glass, and Nan Ya Plastics is integrated via Nittobo. Unitika is most compelling, with asymmetric upside if Qualcomm or hyperscalers sign long deals. … Show more

LPKF Laser is a small-priced option on glass substrates becoming the next generation of AI chip packaging, with 4-10x upside if glass wins. It owns LIDE, the only working laser process that drills precise holes in glass without cracking it. Intel has committed to high-volume glass by 2030, Samsung is piloting and TSMC is evaluating. At a 293M EUR market cap it is pre-revenue inflection with no meaningful EBITDA, which is the point of the bet. x.com 

Nittobo's stock is stuck sideways because it will not raise prices despite a severe T-glass shortage. Per Japanese media reports, management plans no further price increases on low-thermal-expansion glass fabric and will instead accelerate capacity in Fukushima and Taiwan to defend market share. Unlike memory makers aggressively raising prices, Nittobo is too conservative and cares too much about customers, which is a reason not to own it. x.com  x.com 

LPKF Laser & Electronics is a bullish idea, set out in a brief write-up. x.com
