Strategic Selection Guidelines
Choosing a suitable PCB manufacturing partner in the United States requires matching your specific requirements with each company’s core strengths. Consider the following key factors during the evaluation process:
Batch requirements: Match your production needs with the manufacturer’s optimal batch range. Large scale manufacturers like TTM and Sanmina perform well in terms of scale, but may not be cost-effective for prototypes, while companies like Advanced Circuits and Bay Area Circuits focus on small batch, fast turnaround projects.
Technical complexity: Advanced applications that require HDI, high-frequency functionality, or unusual specifications require experts. Summit Interconnect excels in impossible projects, while MOKOPCB handles cutting-edge technology and fast turnover.
Industry compliance: Regulated industries require certified manufacturers. Benchmark and Plexus are leading in medical device compliance, while TTM and Zentech focus on defense requirements with appropriate security licenses.
Service mode preference: Some projects benefit from full-service partnerships (Sanmina’s complete solution), while others require specialized expertise (All Flex’s flexible PCB specialization) or excellent customer service (KeyTronic’s professional support).
