Global copper-clad laminate (CCL) manufacturer Kingboard Laminates (KB) has officially issued a new round of price increase notices. Driven by escalating raw material costs and sustained downstream demand from high-performance computing, the adjustment reflects growing cost pressures across the printed circuit board (PCB) supply chain.
Effective immediately, Kingboard has updated price schedules across core product lines:
- FR-4 Copper-Clad Laminates (All Thicknesses): +10%
- Prepreg (PP) – Thick Cloth (≧ 7628$): +10%
- Prepreg (PP) – Thin Cloth (< 7628): +20%
Divergent Price Hikes: Thin-Cloth Prepreg Under Severe Squeeze
The disproportionate 20% surge in thin-cloth Prepreg highlights critical structural bottlenecks in upstream electronic glass fabric manufacturing.
Thin-cloth prepregs (such as 1080, 2116, and 106) serve as essential dielectric substrates in high-density interconnect (HDI) boards and high-layer-count PCB press cycles. Because domestic fine-yarn glass fabric capacity takes time to ramp up to replace premium overseas imports, short-term supply shortages have intensified, driving up production costs faster than standard thick-cloth varieties.
Timeline: A Year of Escalating CCL Price Adjustments
This latest revision follows an aggressive series of laminate price increases spanning the past 12 months:
| Period | Key Price Movement | Primary Market Driver |
| Late 2025 | Frequent 5%–10% rounds across CEM and FR-4 lines | Initial copper foil surge above RMB 105,000/ton |
| Mid-2026 | Single-round increases expanding to 15% | High resin costs & copper foil processing fee hikes |
| August 2026 | FR-4 up 10%; Thin PP jumps 20% | Critical electronic glass fabric tightness & AI demand |
With over nine rounds of price adjustments over the past year, standard single-sheet FR-4 prices are approaching RMB 300, setting new multi-year highs across the Asian electronics sector.
Upstream Cost Drivers: Copper, Glass Fabric, and Chemical Resins
Kingboard’s official notice attributes the adjustments to compounding pressures across three foundational inputs:
- Copper Foil and Processing Fees: High global copper prices have kept standard foil prices elevated, prompting manufacturers to raise processing surcharges on ultra-thin foils.
- Fine-Yarn Electronic Glass Fabric: Shortages in high-grade electronic glass yarn have created persistent raw material deficits for multi-layer dielectric sheets.
- Epoxy Resins & Flame Retardants: Chemical feedstocks, including epoxy resins and TBBA, remain supply-constrained, compounding per-sheet manufacturing overhead.
- AI and High-Speed Networking Demand: Accelerating global deployment of AI computing clusters and networking infrastructure continues to outpace available high-grade substrate allocations.
Supply Chain Impact: Margin Compression for PCB Manufacturers
The latest price surge places mid-to-downstream electronics manufacturers in a two-way margin squeeze:
- BOM Inflation for HDI Specialists: High-layer and HDI board fabricators consume significant volumes of thin-cloth Prepreg with limited direct material substitution options.
- Pricing Pass-Through Lag: Fixed-price OEM contracts and lengthy automotive/industrial approval cycles delay cost transfers to end customers, forcing PCB factories to absorb short-term cost increases.
- Small-to-Mid Tier Vulnerability: Tier-1 board fabricators leverage scale and long-term inventory buffers, while smaller fabricators face immediate margin contraction on active purchase orders.
Supply Chain Recommendations for Sourcing Managers
To mitigate material cost volatility and avoid lead-time disruptions:
- Audit Active Purchase Orders: Review existing quotes and evaluate raw material indexing clauses with your PCB fabrication partners.
- Secure High-Layer Material Buffers: Forecast thin-cloth PP requirements early to safeguard allocation for complex HDI builds.
- Engage in DFM Optimization: Work with manufacturing engineers to identify cost-efficient layer stackups and standard laminate alternatives where appropriate.
