What happened

An October 2026 industry report circulated by Huayihai PCBA confirms that PTFE (polytetrafluoroethylene) resin systems have become the defined route for next-generation high-speed transmission, with PTFE-based CCL specified for NVIDIA VR300 switch trays and orthogonal backplanes.S1

The same report describes an ABF IC substrate market that flipped from oversupply in 2025 to structural shortage, with lead times at Tier-1 and Tier-2 substrate makers running 48–52 weeks.S1

AI-CCL lead times have stretched to 4–6 months with only 1–2 weeks of channel inventory, and laminate suppliers in Taiwan, Japan and mainland China continue to raise prices, with the pricing cycle the source expects to run through the first half of 2027 or beyond.S1 Suppliers named in the report — Shengyi and Taiwan's Taihon — are scaling output as 2027–2028 demand ramps.S1

The source flags an engineering nuance: PTFE CCL comes in two variants, hybrid-lamination with glass cloth and cloth-free constructions. The cloth-free route yields the best electrical performance but reported yields sit at 10–30%, so supplier selection must weigh process maturity alongside Dk/Df data.S1

Background timeline

  1. — ABF IC substrate market was in oversupply per the source.[S1]
  2. — Industry report positions PTFE resin systems as the defined high-speed route for NVIDIA VR300 switch trays and orthogonal backplanes.[S1]
  3. — Report flags AI-CCL lead times at 4–6 months and channel inventory at 1–2 weeks.[S1]
  4. — Shengyi and Taihon named as scaling output for the 2027–2028 demand window.[S1]
  5. — Laminate pricing cycle expected to run through this window or beyond per the source.[S1]

XAIPART take

Technical impact

PTFE CCL, especially the cloth-free construction, raises signal-integrity headroom for 112 Gb/s and next-generation SerDes channels, but the 10–30% yield window means first-pass design-ins will likely see higher scrap and longer NPI cycles.XAIPART analysis Engineers prototyping on hybrid-lamination with glass cloth should reserve a parallel cloth-free evaluation track once volume tooling is ready, since the two routes trade manufacturability against insertion loss.XAIPART analysis

Market impact

A 48–52 week ABF lead time reshapes sourcing: AI accelerator and switch OEMs will compete for Tier-1 substrate slots, while Tier-2 capacity becomes the realistic hedge for non-leading-edge parts.XAIPART analysis Combined with 4–6 month AI-CCL lead times and 1–2 weeks of channel inventory, buyers should treat laminate and substrate as dual constrained BOMs rather than independent lines, and price escalations from Shengyi, Taihon and Japanese CCL vendors should be modeled into 2027 cost plans.XAIPART analysis

Action

Lock 12-month CCL and ABF supply agreements now and qualify a second-source substrate vendor before Q1 2027 to avoid being trapped behind Tier-1 allocation queues.XAIPART analysis For PTFE-heavy designs, validate both hybrid-lamination and cloth-free stacks at your EMS partner and capture yield data per panel so cost-down conversations are evidence-based rather than anecdotal.XAIPART analysis

XAIPART Forecast

XAIPART expects that if Shengyi and Taihon CCL price lists continue to rise into Q1 2027, AI server BOM cost inflation from laminate alone will exceed the 4–6 month lead-time baseline by Q2 2027, at which point cloth-free PTFE yield will be the gating variable for NVIDIA VR300-class programs. XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty: the report is a single industry-circulated document, named vendors (Shengyi, Taihon) are not independently confirmed in this brief, and the source did not disclose dollar pricing or specific substrate maker allocations.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
