Sunking PCB

Advanced PCB Manufacturing

Advanced boards are routed first, then reviewed — match the right process narrative to HDI, HF, rigid-flex or heavy copper instead of one generic pitch.

How advanced work is handled

Structure triage

Identify the dominant constraint first: density, material, thermal, current or bend.

Parameter tiers

Sample and volume windows may differ; DFM feedback is stage-aware.

Evidence loop

AOI, electrical test, X-ray, microsection and impedance selected by structure.

Equipment & digital backbone

  • Laser drilling and lamination lines
  • LDI pattern exposure in Class 10K cleanroom
  • Fully automatic VCP plating line
  • In-house ENIG, OSP and resin-plug lines
  • Online AOI, AVI and automatic electrical test
  • ERP + MES full-chain traceability

Project inputs & review

  • Dominant constraint notes (density/material/thermal/current/bend)
  • Gerber, stack-up and specialty process requirements
  • Sample or volume stage, quantity and acceptance criteria

Send us the engineering package for this board type

After engineering review we return manufacturability feedback and a quotation. Extreme parameters are reviewed as a combination of material, stack-up and process — not promised as a default simultaneous window.
