High Layer Count PCB

Boards with very high layer counts -- many signal, power and ground layers laminated into one stack -- for designs whose routing can't fit a conventional multilayer build. Stech fabricates stack-ups of up to 100 layers.

Overview

Boards with very high layer counts -- many signal, power and ground layers laminated into one stack -- for designs whose routing can't fit a conventional multilayer build. Stech fabricates stack-ups of up to 100 layers.

Why it matters

High pin-count processors, switch ASICs and test interfaces need more routing channels and more reference planes than a typical multilayer board offers -- and registration, drilling and plating accuracy all have to hold across the full stack.

Typical Applications

  • Networking and telecom backplanes
  • Data center and computing hardware
  • High layer count optical modules
  • ATE test boards and burn-in boards

Manufacturing Considerations

  • Layer-to-layer registration becomes critical as the stack grows
  • Thick boards need high aspect-ratio drilling and plating
  • Back-drilling removes unused via stubs that degrade high-speed signals
  • Laminate loss tier has a larger effect across many signal layers
