Short answer: An EMS quote has four parts — non-recurring engineering (NRE) paid once per design, setup paid every production run, variable per-board cost, and pass-through items like functional test (FCT) fixtures, expedites, and customer-spec consumables. Confusing NRE with setup is the single most common buyer mistake.
Pricing opacity is the dominant complaint from electronics buyers comparing EU and Asian EMS providers. Asian houses often quote "all-in per board" numbers that hide setup and reload fees; EU houses tend to itemise but use inconsistent terminology. This guide standardises the vocabulary and walks through a real quote structure.
The four buckets
| Bucket | Frequency | Typical range (mid-EU EMS, mid-complexity) | What it covers |
|---|---|---|---|
| NRE — Non-Recurring Engineering | Once per design (or per revision) | EUR 400 - 2 500 | DFM review, P&P programming, stencil design, first-article inspection plan, traveler/work-order build |
| Setup / Line Preparation | Every production run | EUR 150 - 800 | Stencil mount, feeder load, paste prep, reflow profile load, oven warm-up, AOI program load |
| Per-board Variable | Per unit | EUR 4 - 60+ | Components (BOM), board, paste, labour-minutes, AOI, packaging |
| Pass-through | As required | At cost + handling | FCT fixtures, custom labels, expedite freight, customer-specified consumables |
The trap: a "EUR 12/board" headline quote on 500 units may carry EUR 1 800 of NRE+setup hidden in line one, making the real per-unit EUR 15.60.
NRE in detail
NRE is the cost of making your design buildable on an SMT line — once. It is not refundable but it amortises across every future build of the same revision. Typical NRE work at SMT assembly:
- DFM review against IPC-7351B land patterns
- Pick-and-place program creation from your centroid file
- Stencil aperture design (often outsourced to laser-cut house, passed at cost + 10%)
- First-article checklist and AOI golden-board image capture
- Traveler creation in our MES, linked to quality-traceability records
A simple 50-component board with clean Altium output costs about EUR 450 in NRE. A 400-component mixed SMT/THT board with hand-drawn schematics and a 12-page revision history can hit EUR 2 200.
Setup vs NRE — the confusion source
Setup is paid every time the line runs your job. It covers physically loading feeders, mounting the stencil, loading the P&P program, and running the first three boards through AOI for verification. For our SMT PCB production line, setup runs 90-180 minutes of line time at EUR 90-180/hour fully-loaded.
NRE is an engineering desk activity. Setup is a manufacturing-floor activity. Different cost centres, different rates.
If you run the same product twice in the same month, NRE is not re-charged. Setup is.
Per-board variable cost drivers
The per-board number depends on:
- BOM cost. Components dominate — typically 55-75% of per-board for mid-complexity. Sourcing through our component sourcing desk can save 8-15% via consolidation with ICAPE, Farnell, Mouser, and Digi-Key spot buys.
- Placement count. Pricing per 1 000 placements is the line-time metric. At 4.8 million placements/year single-shift capacity, our marginal placement cost is EUR 0.018-0.024 depending on package mix.
- Test depth. AOI is in-house and included. FCT is sourced — fixture build and per-board test time are pass-through.
- Board complexity. 0201 components, 0.4 mm-pitch BGA, and bottom-side reflow each add minutes.
- Volume. Per-board drops with quantity; setup is amortised across the run.
- Class. IPC Class 2 is default; Class 3 adds 12-22% for tighter rework windows and 100% AOI.
A worked example: 500-unit run, mid-complexity industrial controller
- BOM: 142 unique parts, 380 placements, mix of 0402-1206 + one QFN + two electrolytics + four THT connectors
- Board: 4-layer, 100 x 80 mm, ENIG
- Test: AOI + FCT (customer-supplied fixture)
- Class: IPC Class 2
| Line item | Cost (EUR) | Per board (EUR) |
|---|---|---|
| NRE (one-off, amortised over 500) | 850 | 1.70 |
| Setup (this run) | 420 | 0.84 |
| BOM (parts only) | — | 11.20 |
| Placement labour + machine | — | 2.10 |
| AOI | — | 0.45 |
| FCT pass-through (customer fixture, 90 sec/board) | — | 1.80 |
| Packaging + label | — | 0.35 |
| Margin | — | 2.90 |
| All-in per board | 21.34 | |
| Quote line: NRE + setup + (500 × variable) | EUR 10 670 |
A second 500-unit run of the same revision the next quarter drops to EUR 9 920 (NRE waived, setup still paid). A 2 000-unit run drops per-board to about EUR 17.50 because setup amortises further.

FCT pass-through — the line item nobody warns about
Functional test is not commodity. A custom bed-of-nails fixture for the example above runs EUR 1 800 - 4 500 depending on test points and harness count. Energetika-VDS sources fixtures from EU partners; the cost is pass-through with a 12% handling fee. Per-board test time at the FCT station is charged at line rate.
If you supply your own fixture, only the per-board test time is charged. This is documented in inspection and testing.
Pricing transparency at EU EMS
Quote sheets from Energetika-VDS itemise:
- NRE with sub-lines (DFM, P&P programming, stencil, traveler)
- Setup with sub-lines (feeder load, stencil mount, first-article)
- BOM with line-by-line component cost and source
- Per-board labour, machine, test
- Margin shown separately
We do not bundle this into a single number on request, but we will if a buyer needs a single PO line. The itemised version stays in the file.
Practical recommendations
- Compare quotes only after normalising to "NRE + setup + (qty × variable)."
- Ask for itemised BOM cost. If the EMS refuses, the markup is hiding somewhere.
- Plan revisions carefully — every revision triggers partial NRE.
- For a JLCPCB alternative, expect EU per-board to be 25-60% higher than China but with lower freight, no import VAT cash-flow hit, and audit rights.
- Use the quote estimator for order-of-magnitude; the formal quote follows DFM.
Frequently asked questions
What is NRE? Non-Recurring Engineering — the one-off cost of preparing your specific design for production. DFM review, pick-and-place programming, stencil design, first-article plan. Paid once per design revision, amortised across all future builds of that revision.
Is setup the same as NRE? No. NRE is engineering desk work, paid once. Setup is line preparation, paid every run. A second batch of the same product pays setup again but not NRE.
What drives per-board cost? In order of impact: BOM (55-75%), placement count and line time, test depth, board complexity (fine-pitch, dual-side), volume, and IPC Class. Class 3 adds 12-22% over Class 2.
How transparent is pricing at EU EMS? At Energetika-VDS, quote sheets are itemised down to BOM line and per-board labour. We will bundle to a single PO line on request but the breakdown remains in file. Customers can audit the cost build on 30 days' notice.
Does volume always help? Yes, but with diminishing returns. The big jump is from prototype to 100 units (setup amortises). The next jump is to 1 000 (BOM tier breaks). Above 5 000 the curve flattens; above 50 000 you should be reviewing automation amortisation on dedicated fixtures.
