Stech PCBA

Primary Capability

High-Complexity PCB

Advanced builds that combine multiple demanding requirements at once — high layer counts, fine features, mixed materials, or unusual mechanical constraints.

Overview

Advanced builds that combine multiple demanding requirements at once — high layer counts, fine features, mixed materials, or unusual mechanical constraints.

Why it matters

Some designs don't fit neatly into one category. A board might need HDI routing density, high-frequency performance, and high-Tg thermal stability at the same time.

Typical Applications

  • Advanced compute and networking hardware
  • Aerospace and defense electronics
  • Multi-technology sensor and RF modules
  • Designs pushing past a single fabrication category

Manufacturing Considerations

  • Combining technologies compounds process complexity, not just cost
  • Design-for-manufacture review matters more here than on any single-technology board
  • Engineering collaboration early in the design cycle reduces late-stage surprises
