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 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's management credibility is the biggest concern after years of overpromising. It missed 2024 and 2025 guidance and is on track to miss 2026, needing H2 revenue of twice its €34.7 million backlog. Expected Q2 production orders for LIDE systems did not arrive and were pushed to H2, and its €1.7 billion advanced-packaging TAM assumes everyone switches fully to glass in 2030. Its technology is great and it leads in TGV, but glass substrates need a couple more years to penetrate meaningfully. … Show more

LPKF Laser & Electronics is a European photonics pick because its laser process is key to glass substrates for AI chip packaging. Per @KawzInvests, Intel, Samsung and TSMC are piloting glass as the next-generation AI packaging material, and LPKF's LIDE process is one of very few able to structure glass at production scale without cracking it. LPKF management said the question is no longer whether glass breaks through in advanced packaging, but when the ramp begins. x.com 

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

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 

LPKF's LIDE technology is production-ready and winning as AI accelerators shift to glass substrates. Glass substrates with high-density through-glass vias deliver better thermal and electrical performance and scalability than organic or silicon for high-power AI chips and data centers, making packaging a key part of the AI buildout. CEO Klaus Fiedler bought shares last month. x.com 

LPKF's stock got ahead of itself, and at around €12 it is worth watching rather than buying, becoming seriously interesting below €10. The glass-substrate thesis is intact: LPKF now sizes its 2030 addressable market at €1.7B, up from €500M, targets 70% share, and is negotiating 2027 ramp orders. But H1 revenue was only €36.5M with negative EBIT and free cash flow, and a steeper ramp could need capital. Next, LPKF must prove it has won a place in the production equipment stack. 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
