Key EMS Services in PCB Manufacturing

Design and Engineering Support

EMS companies optimize PCB designs for manufacturability:

• Telecom Case Study: 45% faster design time, 30% improved signal integrity
• Consumer Electronics Case Study: 35% smaller board size, 40% reduced thermal issues

Company Type	Key Improvements
Telecom Manufacturer	45% faster design time, 25% fewer prototypes, 15% lower material costs
Consumer Electronics Co.	60% quicker component placement, 50% fewer design revisions
Automotive Supplier	70% first-pass design success, 40% reduced interference, 30% fewer field failures

Prototyping & Testing

• Rapid prototyping allows 3–5 design iterations before mass production
• Early defect detection saves 80% on rework costs vs. post-production fixes

Contract PCB Assembly

• Automated pick-and-place systems achieve 35,000+ placements/hour
• In-line AOI/X-ray inspection ensures <100 DPMO (defects per million opportunities)
