🇺🇸 Verification Method
Each company’s domestic manufacturing status is confirmed via: - Direct manufacturer statements (e.g., “not a broker” / “manufactured in the USA”). - Published U.S. facility addresses and certifications. - ITAR or MIL-PRF certifications, which require U.S.-based production.
When a company also has overseas facilities (e.g., TTM), only U.S. production lines were included. Always specify “U.S. build only” in your purchase order if domestic origin is critical.
⚡ Quick Comparison: Speed vs. Capability
| Need | Best Options |
|---|---|
| Fastest Prototype (≤24h) | Sierra Circuits, Sunstone/ASC, AdvancedPCB |
| Complex HDI / Rigid-Flex | Summit Interconnect, AdvancedPCB, TTM |
| ITAR / Defense / Aerospace | AdvancedPCB (APCT), TTM, Summit |
| RF / Microwave / PTFE | Summit, ASC, TTM |
| Low Volume / Hobbyist-Friendly | Sunstone, Sierra Circuits |
🧩 Notes
- Most domestic PCB fabs do not disclose annual board counts, but revenue and site count indicate capacity tiers.
- Customer reviews vary by application — high-end fabs tend to score lower on consumer review sites due to industrial B2B focus.
Author’s recommendation:
For critical, certified, or military-grade applications — APCT (AdvancedPCB), Summit, or TTM are the safest U.S. domestic bets.
For rapid-turn prototypes or R&D work — Sierra Circuits or Sunstone/ASC deliver top speed and solid reliability.
