36 I-CONNECT007 MAGAZINE I APRIL 2026 run on metals and prices spike, other investors re- spond to those run-ups with a profit-taking sell-off, triggering a correction. An industry-wide average puts silver at 3–8% of printed circuit board fabrication costs, gold at 5–15%, and copper, of course, leading the way at 15–25% of the total fabrication cost. An increase in copper prices of 20% over a year can trigger an increase in PCB fabrication costs of 3–5%, which may be the full profit margin for a company build- ing production-level quantities of PCBs. Looking at data from COMEX and the London Metal Exchange, the following table captures just how volatile prices have been in the first quarter of 2026. Gold's volatility is mostly driven by investors, while silver is experiencing swings characterized by analysts as "speculative-grade volatility." Cop- per may sit between the two, but copper's volatility tends to come from high industrial demand coun- tered by supply risks and tight inventory. So, how does this look when translated to a specific work order? By running some research tools, we estimated the impact of current metal costs on the cost per piece for three common board configurations: standard ENIG, heavy copper, and hard gold. Scenario A: Standard 8-layer ENIG board Price Changes • Copper +15% • Gold +10% Net effect: ~+2.0–2.8% fab cost increase and increasingly quoted as a line-item surcharge, not absorbed Scenario B: Heavy copper/power electronics board Price Changes • Copper +20% • No gold (OSP finish) Net effect: ~+3.5–5.0% fab cost increase and high risk of mid-quarter repricing Figure 1: Typical cost exposure by metal (fabrication only).
