What Is NPI PCB Assembly?

New Product Introduction (NPI) is the manufacturing stage between prototype validation and repeat production.

During NPI, PCB and BOM revisions, approved components, sourcing, assembly documentation, programming, functional testing, inspection requirements, and production documentation are reviewed according to the project requirements.

The objective is to establish a manufacturing process that can be repeated consistently before larger production quantities are released.

From Prototype to NPI and Pilot Production

NPI normally begins after the product has reached an appropriate level of prototype validation.

Issues identified during prototype PCB assembly can be reviewed before the next build so that PCB revisions, BOM changes, sourcing, programming, testing, and manufacturing documentation can be updated where required.

A typical manufacturing transition may follow:

Prototype Build → Engineering Review → NPI Build → Pilot Production → Process Review → Production Release → Repeat Manufacturing

The exact sequence depends on the product, development stage, validation requirements, and expected production volume.

NPI PCB Assembly Process

Our NPI process focuses on production readiness rather than simply increasing build quantity.

Depending on the project, the process may include:

Engineering Review → BOM & Supply Chain Review → PCB / Assembly Documentation Review → DFM Review → PCB Fabrication

Component Procurement → Material Preparation → SMT / THT Process Setup → NPI Build → First Article Inspection

Programming → Functional Testing → Process Review → Manufacturing Documentation → Pilot Production → Production Release

The exact process depends on the PCB design, component packages, sourcing requirements, programming requirements, testing scope, and production objectives.

Manufacturing observations identified during the NPI build can be reviewed before the next production stage is released.

BOM & Supply Chain Review During NPI

A design can be electrically complete while still containing sourcing risks that may affect production.

During NPI, BOM and supply chain review may include:

Manufacturer part number verification
Component availability
Manufacturer lead time
Lifecycle status
Obsolete or NRND components
MOQ / SPQ
Reel, tray and packaging requirements
Allocation risk
Approved manufacturer / AVL requirements
Long-lead-time components
Second-source availability

Components that are practical for a prototype build may not always be suitable for repeat production due to availability, lifecycle, lead time, MOQ, or cost.

Where appropriate, potential second-source or alternative components can be reviewed. Alternative components are not substituted without customer review and approval.

Programming & Functional Testing During NPI

Programming and functional testing should be considered before repeat production begins.

Depending on the product, we can support:

IC / MCU Programming
Firmware Loading
Programming Verification
Power-On Verification
ICT
Functional Testing
Customer-Defined Test Procedures
Communication Interface Testing
Test Fixture Integration

For customer-specific functional testing, our engineering team can review the test procedure, test points, operating conditions, required measurements, communication interfaces, programming requirements, and pass / fail criteria.

Where required, a production test fixture can be designed and built according to the agreed test method.

Fixture development scope and applicable NRE or development costs are reviewed before implementation.

Pilot Production

Pilot production provides an intermediate manufacturing stage between early NPI builds and repeat production.

A pilot build can be used to verify:

PCB and BOM revisions
Approved components
Manufacturing documentation
Assembly process
Programming procedure
Functional test procedure
Test fixture
Inspection requirements
Material preparation
Production workflow
Packaging requirements
Yield observations

Issues identified during pilot production can be reviewed before larger production quantities are released.

This helps confirm that the manufacturing process is stable and documented before repeat production begins.

NPI & Pilot Production Quantities

There is no fixed quantity that defines every NPI or pilot production build.

The appropriate quantity depends on product complexity, development stage, validation requirements, expected design changes, functional testing, component availability, production forecast, and the planned production ramp.

An NPI project may begin with a relatively small engineering build and progress through pilot production before repeat manufacturing quantities are released.

If future production quantities are known, please include them in the RFQ. Prototype, NPI, pilot, and production quantities can be evaluated separately because material purchasing, setup, testing, fixtures, process controls, and production planning may differ at each stage.

NPI PCB Assembly FAQ

What is the difference between prototype PCB assembly and NPI?

Prototype PCB assembly is primarily used to build and evaluate an early-stage design.

NPI focuses on preparing the product and manufacturing process for controlled production. This can include BOM review, sourcing, DFM, process setup, programming, functional testing, manufacturing documentation, and pilot production.

Do we need a pilot run before production?

Not every project requires the same production sequence.

The need for a pilot run depends on product complexity, design maturity, testing requirements, expected production volume, manufacturing risk, and customer requirements.

Can you support component alternatives during NPI?

Yes. We can review component availability, lifecycle status, lead time, package compatibility, and potential second-source components.

Alternative components are submitted for customer review and approval before purchasing or assembly.

Can you support programming and functional testing?

Yes. Programming and functional test requirements can be incorporated into the NPI manufacturing process.

Where required, we can review firmware loading, programming procedures, test points, communication interfaces, customer-defined test procedures, pass / fail criteria, and fixture requirements.
