LPKF
Relevance to glass substrates
lpkf is a candidate equipment/process-control exposure for glass substrate packaging. Its LIDE process and NEXAR system pages directly address TGV formation, RDL ablation, and glass-to-glass bonding.
Evidence summary
LPKF's NEXAR page describes a production-ready system platform for glass substrates in advanced packaging. The company says the platform covers defect-free TGV formation, damage-free RDL ablation, and high-speed glass-to-glass bonding, with wafer formats up to 300 mm and panels up to 515 mm x 510 mm.
LPKF's LIDE page describes a two-step process: ultrafast laser modification followed by selective wet etching. Claimed advantages include no micro-cracks or thermal damage, high aspect ratios up to 1:50 for TGVs, via diameters down to 5 micrometers, low sidewall roughness, and panel-scale positional accuracy.
Investment role
This is the cleanest process-step exposure found in the first pass, but the evidence is still vendor-marketing quality. To graduate from lead to candidate, LPKF needs order/backlog/customer evidence tied to glass substrate production, not just a technically plausible product page.
Risks and caveats
- LPKF claims are promotional and not yet customer-verified.
- The bottleneck may be integration/yield/qualification rather than the LIDE tool itself.
- Competing TGV formation methods or internal customer processes could erode pricing power.
Next checks
- Review LPKF filings/calls for NEXAR/LIDE orders, backlog, customer concentration, segment revenue, gross margin, and capacity.
- Look for customer references from Absolics, Intel, OSATs, foundries, or glass suppliers.
- Compare with alternative TGV, laser drilling, etch, and plating vendors before assigning scarcity.
