Physics / mechanism
Electronics manufacturing, in the sense captured by the available sources, is the industrial chain that turns bare substrate into functioning assemblies: printed circuit board (PCB) fabrication, followed by printed circuit board assembly (PCBA) in which components are populated onto the finished board. The two stages are tracked as separate markets, with PCBA the larger of the pair by revenue.
The key economic parameters visible in the sources are market scale, growth rate and geographic concentration rather than process physics. The global PCB market was roughly $89-90bn in 2025 growing at about 5.2% CAGR, while capacity share is heavily skewed: Asia holds over 70% of global PCB capacity, with China alone accounting for more than 60% of global production capacity.
Regional output is concentrated in a small number of firms and countries. Europe accounts for roughly $9.07bn, about 12.2% of global revenue, clustered in Austria, Germany and Switzerland, where AT&S, Schweizer and KSG together represent more than half of EU output. US fabrication output fell from more than 30% of the global total in the early 2000s to under 5% today.
Competitive landscape
The sources support only a geographic comparison, not a technology comparison. On that axis, the landscape is a single dominant bloc (Asia, and specifically China) facing two much smaller incumbent bases: a European cluster with roughly an eighth of global revenue concentrated in three countries and three firms, and a US base that has contracted to marginal share. Any reshoring thesis therefore starts from a position where Western fabrication capacity is a small fraction of demand. Electronics manufacturing also sits adjacent to, and downstream of, national semiconductor policy: UK coverage of the sector has been framed alongside UK semiconductor strategy ref.
Evidence base
- The global PCB market was approximately $89-90bn in 2025, growing at around 5.2% CAGR, with the PCBA market larger again.
- Asia accounted for roughly 55-60%+ of global PCB revenue and more than 70% of capacity as of the June 2026 digest.
- China alone accounts for more than 60% of global PCB production capacity.
- Europe represents about $9.07bn and 12.2% share, with AT&S, Schweizer and KSG together exceeding half of EU output.
- US PCB fabrication output declined from over 30% of the global total in the early 2000s to under 5%.
- UK electronics manufacturing was profiled as a distinct policy and industry topic in December 2021, tracked alongside UK semiconductor strategy ref.
Frontier (open questions)
- What is the delivered cost premium, per square metre of finished PCB and per populated assembly, for Western fabrication versus Chinese supply at equivalent layer count and technology class?
- Which specific PCB technology classes (HDI, high layer count, RF/high-frequency substrates) have no qualified Western supplier, and what capex would close each gap?
- Does announced Western reshoring capacity translate into measurable share recovery from the sub-5% US baseline, and on what timescale?
- What fraction of European output growth is driven by defence and aerospace qualification requirements rather than commercial demand?
