Frequently Asked Questions

We have a working prototype, but we don't know how many design iterations it will take to reach production-ready. How do you manage that uncertainty?

This is the central challenge of the NTI stage — and the reason iteration needs to be structured, not open-ended. We start by establishing clear Design Validation Test (DVT) criteria and certification goals upfront, so every iteration has a defined target rather than a vague sense of "good enough." Our DFX Support identifies design limitations early — before they multiply across spins — and each iteration loop tightens around a specific set of resolved issues. Most products move through one to three spins between s1 and a pilot-ready design. We track milestone by milestone so you're never iterating blind.

What's the difference between a technology POC and a business POC — and why does it matter at this stage?

A technology POC proves your core idea is technically possible. A business POC proves your product works the way real users expect it to, at a quality level the market will accept, and at a cost structure that supports a viable business. The NTI stage is specifically designed to close that gap. Transitioning too early — sending a tech POC into production — is one of the most expensive mistakes hardware startups make. We accelerate the transition by stress-testing your design against real performance requirements, user conditions, and manufacturing constraints before you commit to tooling.

What is DFX, and why does it determine how many design spins we'll need?

DFX stands for Design for Excellence — a set of engineering disciplines that ensure your design is optimized for how it will actually be built, tested, assembled, and used in the field. It includes DFM (Design for Manufacturability), DFT (Design for Testability), DFA (Design for Assembly), and DFR (Design for Reliability). Ignoring DFX at the prototype stage is the primary reason products require costly late-stage redesigns. Our DFX Support and Design Limitation Research runs in parallel with your iteration cycle, catching issues at the point where fixing them is cheap rather than at NPI where it is not.

How do we define what "good enough" looks like before we build pilot units — so we're not testing without a standard?

Without defined test requirements, pilot runs produce ambiguous results — you don't know if what you're measuring represents a pass or a failure. Before any units are built, we establish Product Design Files and Test Requirements aligned to your quality targets and certification goals. This creates an objective standard for Engineering Validation Tests (EVT) and Design Validation Tests (DVT) — so every build is measured against something real, and "done" has a clear definition that your team, your investors, and your manufacturing partner all share.

How many pilot units should we build, and how should we use them strategically?

The right number depends on what you're trying to prove and to whom. Within our 1–250 unit range, a common approach is to allocate units across four parallel purposes: certification lab testing (units get destroyed — plan for them), internal engineering QA (stress testing, edge cases, failure mode analysis), investor or customer beta validation (real-world use in your target environment), and manufacturing process verification (confirming the production line performs consistently). We help you plan the right quantity and unit allocation for your specific stage and goals — not just build to an arbitrary number.

How do we know when we're genuinely ready to move to NPI production — and how do we avoid moving too early?

Moving to NPI before your design is truly locked is the single most expensive mistake in hardware development — tooling is committed, supply chain is ordered, and any design change means scrapping work and restarting. The threshold for NPI readiness is a finalized Control Book: a complete manufacturing package that documents your design files, test specifications, process controls, BOM, and quality standards in a form the production floor can execute without interpretation. We deliver a verified Control Book and confirmed Pilot Products as the exit criteria for NTI — so the decision to move to NPI is based on evidence, not optimism.

How does NexPCB set up the supply chain during NTI so we're not scrambling when production volumes hit?

A: Supply chain setup during NTI is not preparation — it's risk management. Long-lead components, minimum order quantity commitments, second-source qualification, and supplier onboarding all need to begin during your pilot run phase, not after you've committed to a production launch date. We run Cash Flow and Technology Supply Chain Analysis in parallel with design iteration, identifying which components require early commitment, where single-source dependencies exist, and what inventory strategy fits your ramp timeline. By the time you enter NPI, your supply chain is structured — not improvised.

Each design spin costs time and money. How do we plan our budget across an unpredictable iteration cycle?

Unpredictable iteration spend is what kills startup runway at the NTI stage. We address this through upfront Manufacturing Process Finalization and Budgeting before pilot builds begin, and deliver a formal NPI Proposal and Budget Report that gives you a cost model spanning iterations, pilot unit production, tooling requirements, and the full NPI transition. This lets you plan cash deployment against a structured milestone roadmap rather than treating each design spin as a surprise expense. You'll also have a document your board or investors can scrutinize — not a spreadsheet built on assumptions.
