From bare board
to finished assembly.

Start with the service you need. Combine fabrication, sourcing and assembly when your project calls for a complete build.

01 / FABRICATE

PCB Manufacturing

Define the stackup, materials, copper, finish and acceptance requirements around your actual design.

  • Prototype and multilayer boards
  • HDI, flex and rigid-flex review
  • RF, impedance and thermal requirements

03 / INTEGRATE

Components & Box Build

Plan approved components, firmware, cables, enclosures and final checks as part of your product build.

  • BOM availability and substitutions
  • Programming and assembly instructions
  • Product-level acceptance checks
Discuss product integration →
Built around engineering decisions

Know what matters
before you release.

Small gaps in a fabrication drawing or BOM can become expensive questions on the production floor. Make the technical requirements visible at the start.

Final feasibility, tolerances and delivery dates are confirmed against your design files.

A clear path to your next build

Less guesswork.
A better handoff.

Engineers and procurement teams need the same answer: what will be built, what will be checked, what it costs and when it can ship.

Prepare your quotation package →

Share the design and build brief

Send the released fabrication data, quantity and requirements. For PCBA, add the BOM, pick-and-place data and assembly drawings.

Resolve the questions that affect cost

Confirm material choices, component availability, test scope and any assumptions before approving the quote.

Approve the revision for production

Keep the approved files, engineering changes and acceptance requirements together in one controlled build package.

Review results and prepare the next build

Agree on inspection records, packaging and repeat-order requirements so the next release starts from a known baseline.

Before your first inquiry

A few practical answers.

Can I request fabrication and assembly together?

Yes. Choose turnkey PCB + assembly in the inquiry form and include your fabrication files, BOM, placement data and build instructions. The quote should identify the scope and any missing information.

How are pricing and delivery dates confirmed?

They depend on the released files, materials, quantity, component availability and test requirements. Submit your requested date so feasibility can be checked before you commit to a build.

What if the design is not ready for production?

Describe the open questions and the current revision. A pre-production inquiry can focus on stackup, materials, sourcing or assembly constraints. Do not treat an early estimate as approval of an unfinished design.

Can we discuss an NDA before sharing files?

Contact the team before sending sensitive design information. Identify your project and the confidentiality requirements so an appropriate agreement can be discussed.
