Gold at $5,595: ENIG Surface Finish Costs Break Industry Records

On January 29, 2026, gold struck an all-time high of $5,595 per troy ounce. As of March 26, the spot price stood at $4,386/oz — still up $1,364 year-on-year. The metal more than doubled in value from approximately $2,600/oz in early 2025 to the January 2026 peak, an extraordinary 115% run in under 14 months. Drivers include record central bank gold purchases (China’s PBOC extended purchases for 15 consecutive months through January 2026), geopolitical risk premiums from ongoing Middle East tensions, and structural safe-haven demand as U.S. tariff uncertainty persisted.

For PCB manufacturing, gold’s relevance is immediate and direct. ENIG (Electroless Nickel Immersion Gold) is the dominant surface finish for high-reliability PCBs — from smartphone motherboards to AI server HDI boards to automotive ADAS controllers. The process deposits 0.05–0.15 μm of immersion gold over an electroless nickel underlayer. Although the gold layer is ultrathin, gold’s raw material cost accounts for 60–80% of total ENIG process expense. Korean PCB substrate makers TLB and Simmtech confirmed that potassium gold cyanide (PGC) — the key gold-bearing chemical used in ENIG plating — surged from approximately ₩50,000 per gram in 2023 to ₩99,000 per gram by Q3 2025, a near-100% increase before the January 2026 gold spike.

The Supporting Cast: Glass Fiber Cloth and Epoxy Resin Also Rising

Beyond copper and gold, the two other primary CCL inputs are also under pricing pressure. Electronic glass fiber cloth — the dielectric reinforcement in FR4 and high-speed laminates — rose 12% year-on-year in 2025, with some suppliers announcing 20% increases for 2026. Glass fiber manufacturers serve wind power, construction, and automotive composite markets simultaneously, creating competition for electronics-grade production capacity that is tightening supply and raising prices.

Epoxy resin — the binding matrix in CCL laminates — tells a more mixed story. Asian prices softened through H1 2025 on weak construction demand in China. However, European laminate producers that source epoxy from European chemical suppliers have seen sustained price pressure: AOC announced a €150–200/tonne increase on its epoxy vinyl ester resin portfolio effective March 1, 2026, adding to increases already implemented in 2025. For high-performance PCB-grade laminates requiring purified electronics-grade resins, the cost trends are less favourable than for construction-grade materials.

Rare earth materials used in ceramic capacitors — particularly Yttrium, critical to high-capacity MLCCs — remain heavily supply-restricted, according to the March 2026 Electronic Component Market Review published by ESCATEC. Even minor supply disruptions for rare earth inputs quickly restrict availability and make lead times less forgiving, adding further cost pressure to the broader electronics bill of materials.

“Copper is continuing to climb, with peaks in January, now showing $13,500 per tonne. Analog Devices applied a portfolio price increase in February 2026 averaging 15%. Infineon will be applying price adjustments from 1st April 2026. TE Connectivity is expected to align its pricing from March onwards, with some increases anticipated at 30%.”

How PCB Buyers Should Respond: Five Practical Strategies

Outlook: Will This Ease in 2026?

Goldman Sachs is more cautious than J.P. Morgan, projecting LME copper remaining in a $10,000–$11,000/t range for 2026, consistent with a small market surplus of around 160,000 tonnes. The Reuters consensus of approximately $10,500/t reflects wide dispersion in forecasts — ranging from Goldman’s cautious $10,710/t to J.P. Morgan’s bullish $12,075/t. Even the bear case implies copper remaining significantly above historical averages, sustaining pressure on PCB raw material costs through the year.

Gold has retreated from its January 29 peak of $5,595 to the $4,300–$4,600 range as of late March 2026. Goldman Sachs revised its end-April 2026 gold target upward to $4,600/oz in a March 21 research note, citing eventual Fed pivot signalling and sustained central bank buying. The bank’s bull case for year-end remains $5,200. Goldman’s PCB cost implication: gold will remain significantly above the $2,600 level seen in early 2025 through the full year, sustaining ENIG cost pressure even after the January peak.

The adoption of next-generation M9 CCL materials — beginning to ramp in 2026 for AI server applications — is expected to push high-end PCB prices a further 30–50% higher as this material is qualified and adopted. This is not a commodity cost increase but a technology transition, and customers dependent on cutting-edge AI board specifications cannot avoid it. For the broader PCB market, the March 2026 supplier notifications from Mitsui Kinzoku and Mitsubishi Gas Chemical should be treated as signals of a new pricing floor, not temporary anomalies.
