Turnkey PCB Assembly
Bring PCB fabrication, component sourcing, assembly, and agreed testing together with MV Circuit. One coordinated build helps you manage materials, engineering approvals, and delivery from the same release package.
- PCB Fabrication & BOM-Based Component Sourcing
- Purchasing Decisions & Alternatives Approved Before Use
- Assembly, Inspection & Delivery Coordinated Together
ONE COORDINATED BUILD
From Your Approved Design to Finished PCB Assemblies
Spend less time coordinating separate suppliers
A turnkey project connects the bare board, purchased parts, assembly program, and acceptance plan. Your engineering team supplies a controlled design package; we coordinate the manufacturing tasks and bring open questions back for approval.
This approach is useful when you want PCB fabrication and component purchasing managed alongside assembly. It also makes material availability, setup needs, and testing visible before the production schedule is confirmed.
The scope follows your quotation. Firmware loading, functional test fixtures, special finishes, coating, and additional mechanical work are reviewed and included when agreed.
ASSEMBLY OPTIONS
A Turnkey Route for Different Board Constructions
Mixed-Technology Assemblies
Combine surface-mount circuitry with through-hole connectors, terminals, and mechanically loaded components.
Compact Sensor Assemblies
Bring small sensing and interface boards together with the specified components, handling requirements, and test access.
COMPONENT SOURCING
Make Purchasing Decisions Before They Affect the Build
A complete BOM is the starting point
Provide manufacturer names and exact part numbers, reference designators, quantities, and do-not-fit positions. Add approved alternatives, sourcing restrictions, and any traceability or date-code requirements.
We review availability and flag purchasing questions before proceeding. If a device is unavailable or has a long lead time, proposed alternatives return to your team for technical approval.
For partial turnkey projects, a line-by-line responsibility list separates purchased and customer-supplied materials. Agree how shortages, setup quantities, unused stock, and future orders will be handled.

TURNKEY WORKFLOW
How Your Turnkey Order Comes Together
01
Agree the Turnkey Scope
Define which fabrication, sourcing, assembly, and test operations are included. Release one coordinated file package and identify decisions that need customer approval.
02
Approve the Purchasing Route
Review exact manufacturer part numbers, supplier requirements, lead times, and proposed alternatives. Resolve purchasing questions before components are committed.
03
Connect Board Fabrication to the BOM
Coordinate PCB construction, panel format, component footprints, and assembly needs so the fabricated boards and purchased parts belong to the same approved revision.
04
Close Material Gaps Before Setup
Check kit completeness, packaging, moisture-sensitive handling, and any supplied parts. Flag shortages early and agree the action before the assembly line is scheduled.
05
Run the Coordinated Assembly Build
Bring the released boards, material kits, placement program, and soldering instructions together. Apply agreed inspection or first-article checkpoints before continuing.
06
Deliver Assemblies and Close the Order
Confirm the delivered revision, agreed test results, protective packaging, and shipment plan. Record how excess components will be returned or held for an identified repeat build.
QUALITY & ACCEPTANCE
Define What Each Inspection and Test Must Prove
Match the verification plan to your product
Incoming checks help confirm that the intended materials reach the line. Assembly inspection checks accessible workmanship features; hidden solder joints may need an agreed X-ray plan.
Programming and functional testing need more than a powered board. Supply the firmware, connection details, fixture requirements, operating sequence, and measurable limits so results have a clear meaning.
Keep inspection findings and approved deviations connected to the delivered revision. Product validation and regulatory certification follow their own requirements and are not implied by assembly inspection.

COMMON QUESTIONS
Turnkey PCB Assembly FAQ
What is turnkey PCB assembly?
Turnkey PCB assembly combines bare-board fabrication, component purchasing, assembly, and the agreed inspection and test services in one coordinated project. You release the design files and approve technical or purchasing decisions; MV Circuit coordinates the manufacturing work against that approved package.
What is included in a turnkey quotation?
The quotation should identify PCB fabrication, components, stencil and setup, assembly operations, inspection, programming, testing, packaging, and delivery terms. Special tooling, fixtures, conformal coating, or other requested operations are listed separately where applicable. Confirm the scope before releasing the order.
Which files are required for a turnkey PCB assembly order?
Send Gerber or agreed fabrication data with drill files, a fabrication drawing and stack-up, BOM with manufacturer part numbers, pick-and-place data, and an assembly drawing. Include quantities, revision identifiers, do-not-fit positions, approved alternatives, firmware, and test requirements.
How are components selected and purchased?
Purchasing follows the approved BOM, manufacturer part numbers, supplier requirements, and agreed sourcing route. Component availability, packaging, lead times, and handling requirements are reviewed before commitment. Identify parts that require a particular authorized source or additional traceability evidence.
Will you substitute unavailable components automatically?
A proposed substitute must be reviewed and approved before use. Matching a nominal value alone is insufficient: footprint, ratings, tolerance, temperature range, lifecycle, and firmware compatibility can matter. Record the approved manufacturer part number and applicable revision in the BOM or change log.
Can I supply some of the components?
Yes. A partial turnkey arrangement can combine your supplied parts with components purchased by MV Circuit. Agree the responsibility for every line item, quantities including any setup allowance, delivery dates, packaging, and the treatment of unused stock before production.
Can turnkey orders cover both prototypes and repeat production?
Turnkey support can be arranged for engineering samples, small batches, and repeat builds. Prototype orders need clear evaluation goals and revision control. Repeat production needs a stable BOM, controlled alternatives, defined test coverage, and an agreed plan for long-lead or lifecycle-sensitive components.
What inspections and tests are included?
The agreed plan may include incoming checks, visual inspection, AOI, and X-ray where specified for hidden joints. Firmware loading and functional tests require suitable files, access, fixtures, procedures, and pass/fail criteria. Workmanship inspection does not establish complete product functionality or regulatory compliance.
How is turnkey assembly lead time determined?
The complete schedule depends on engineering approval, PCB fabrication, component availability, assembly preparation, and test requirements. A stocked component list does not by itself establish the shipment date. Confirm procurement release conditions and the effect of long-lead parts with the project team.
What happens to unused components and future repeat orders?
Agree whether excess materials are returned, held for an identified repeat build, or handled another way. Define ownership, storage conditions, moisture-sensitive handling, inventory records, and retention periods. A repeat order should reconfirm the revision, component availability, approved alternatives, and test requirements.
