NPI Engineering and Prototyping
NPI is where ideas meet production reality. Most product programs lose weeks — sometimes months — in the gap between "design complete" and "production ready": failed builds, BOM gaps, fixture problems, test escapes. Elleve's NPI engineering function is dedicated to closing that gap. Our NPI engineers work alongside your design team from before the first board is fabricated. We review schematics for DFM, BOM for sourcing, mechanical for fabrication, and test strategy for coverage — then build first articles, capture findings, and iterate fast. By the time a design transitions to volume production, every issue worth catching has already been caught, and the same operators who built the prototype will build the production run.

Capabilities included in this service
Design for Manufacturing (DFM) Review
Independent DFM analysis on every design — component spacing, polarity marking, panelization, fiducials, solder mask relief, and more.
Design for Assembly (DFA) Review
Assembly sequence, fixture access, hand-load minimization, and operator-friendly orientation reviewed before the first build.
Design for Test (DFT) Review
Test point coverage, ICT fixture access, boundary scan opportunities, functional test hooks — designed in, not retrofitted.
Rapid Prototyping
First articles in days, not weeks; same SMT lines used for production, so what gets built at proto scales without surprise.
EVT / DVT / PVT Builds
Engineering, design, and production validation builds with structured findings reports and disposition tracking.
NPI Documentation & Process Transition
Work instructions, test plans, fixture documentation, and process control plans handed over for clean volume ramp.
Our Process
A disciplined, repeatable process that eliminates surprises at every stage.
Schematic, layout, BOM, mechanical, and test strategy reviewed end-to-end before any manufacturing begins.
Findings documented and triaged — fix-now, fix-next-rev, accept-with-mitigation — with clear ownership.
Hand-stencil or jet-printed paste, manual placement validation, full traceability from board zero.
Findings fed back to design, second-build issues addressed, process windows characterized.
EVT, DVT, or PVT build at meaningful volume to confirm yield, test coverage, and operator readiness.
Full documentation package — work instructions, test plans, fixtures, control plans — released into production.
What we certify to
Speed
Quick-turn first articles in days; same-day SMT for urgent NPI builds
Continuity
Same SMT lines for prototype and production — no learning curve at ramp
Standards
IPC-A-610 Class 2 (Class 3 available), IPC-J-STD-001 compliant prototype builds
Engineering
Dedicated NPI engineers, not just hands — DFM/DFA/DFT-trained
Sourcing
Component sourcing for prototypes through the same authorized channels as production
Documentation
First-article test reports, findings tracker, full traceability from build zero
Why this service is different at Elleve
The reasons our clients stay long-term — specific to this service.
NPI is owned by engineers who can read schematics and challenge the design, not just operators waiting for parts.
The line, fixtures, and operators that build your first article scale your volume — no rebuild at ramp.
Every design weakness surfaced during NPI is one that doesn't scrap thousands of units in production.
Production receives a complete, validated package — not tribal knowledge from a prototype build.
Who we build for
Each industry has its own standards, certifications, and reliability expectations. We bring the right engineering discipline to each one — from consumer IoT to aerospace electronics.
Built for the meters, controllers, and systems that keep the lights on.
Electronics for a world that doesn't go offline. Always-on reliability.
EV charging, in-vehicle electronics, and transportation infrastructure.
Electronics tough enough for the toughest environments.
Healthcare runs on reliability. We build it in from day one.
Electronics that hold the line — on land, at sea, in the sky.
