share:

  • HDI / Rigid-Flex / Controlled Impedance / Via-in-Pad
  • DFM & stackup co-design; fast, practical engineering feedback
  • Full traceability, IPC/ISO-based QA, panel-level impedance coupons
  • Turn-key sourcing or consigned kits with clear substitution rules
  • Transparent lead times and yield-driven quoting

OEM vs. ODM — Which Model Fits Your Project?

TopicOEM (Build-to-Print)ODM (Co-Design & Customization)
Design ownershipYou provide complete design (Gerber/ODB++/IPC-2581, BOM, PnP, STEP)We help define stackup, parts, substitutions; schematic/layout if needed
Change controlBased on your documents; engineering review before releaseJoint milestones (PRD → EVT → DVT → PVT) and formal ECO flow
Cost & scheduleFaster onboarding, predictable costMore engineering upfront, better manufacturability & lifetime cost
Best forMature designs, repeat orders, clear test specsNew products, rapid validation, BOM cost/Yield optimization

Engagement Models

1) OEM — Build-to-Print
Input: full design package.
Output: traceable production, 100% E-test, X-ray where needed, stable mass delivery.

2) ODM — Co-Design & Manufacturing
Input: functional targets, interfaces, environment/reliability, budget & timeline.
Output: stackup/material proposal, key component selection/substitution list, layout constraints, prototypes & validation, ramp-to-mass plan.


Process & Quality Control

  • DFM/DFT early lock-in: min line/space, vias (uVia/VIP/back-drill), annular ring, impedance tolerance.
  • Materials & stackups: selected by signal/power/thermal needs; low-loss or hybrid options when required.
  • Manufacturing: LDI imaging, laser microvias, resin/copper fill & cap, sequential lamination, controlled impedance.
  • Inspection & test: AOI (inner/outer), flying-probe/ICT, BGA X-ray, TDR coupons per panel, FCT as specified.
  • Traceability: lot-to-material-to-test data linkage; first-article & in-process checkpoints.

IP & Confidentiality

  • Mutual NDA; least-privilege file access.
  • Project-level data segregation and retention per your policy.
  • Optional file encryption/version control and audit logs.

Deliverables

  • Fabrication: final stackup, impedance/TDR report, key dimension report, first-article/process checks.
  • Assembly: reflow profile, X-ray report, approved alternates list (if any).
  • Test: FCT/ICT logs, unique SNs with timestamps, programming records.
  • Certificates: RoHS/REACH declarations, COC/COA; material compliance on request.

Lead-Time Bands (typical)

  • PCB prototypes: X–Y working days (by layer/complexity).
  • Turn-key PCBA prototypes: X–Y working days after materials are complete.
  • Pilot/MP: SLA and capacity curve after BOM lock & tooling.

Expedite options available after yield/feasibility review.


Sourcing & Substitution Rules

  • Turn-key: we procure full BOM with incoming inspection.
  • Consigned/partial: you supply critical ICs or custom parts; we complete the rest.
  • Substitutions: only same footprint and equal/higher spec; written approval required. No substitutions for key ICs unless explicitly allowed.

Test & Programming

  • Test matrix per project: flying-probe / ICT / boundary scan / FCT.
  • Target coverage and pass/fail thresholds defined up front.
  • Firmware programming and serialization: unique SN, QR/1D labels, log format agreed.

OEM/ODM RFQ Checklist

OEM: Gerber/ODB++/IPC-2581, BOM with MPNs & substitution policy, PnP/XY, STEP, assembly drawings, test spec, target lead time & quantities.
ODM: PRD (functions, interfaces, power), performance/reliability targets, environment & certifications (e.g., automotive/medical), cost & delivery goals, prototype schedule (EVT/DVT/PVT).


FAQs

Q1. Can you mix materials for low-loss/high-speed layers?
Yes. We can use low-Dk/Df for high-speed layers and high-TG FR-4 elsewhere, with thermal/warpage analysis and defined process windows.

Q2. How do you control impedance tolerance?
Stackup and copper thickness locked before release; TDR coupons per panel; typical ±10%, tighter on validated builds.

Q3. Does via-in-pad impact lead time?
VIP (fill & cap) adds processes/cure time. Use VIP only where density demands it and standard vias elsewhere to balance cost/lead time.

Q4. Do you support small-batch, high-mix NPI?
Yes. We recommend staged ramp with shared fixtures/stencils to balance speed and yield.

Q5. How are alternates approved?
By written rules agreed at RFQ. All alternates require engineering + purchasing sign-off with returned BOM change records.
