What Aerospace PCB Assembly Costs, and What Drives It
An aerospace circuit card assembly is priced on its bare board, its components and how they are sourced, setup, placement, inspection, coating, test and records. On low volume flight and defense builds, part grade, counterfeit controls and test usually move the price more than placement does.
Updated
The short answer
An aerospace circuit card assembly costs what its bare board, its components, the counterfeit controls on those components, the setup, the placement and soldering, the inspection, the coating, the test and the records add up to. On low volume flight and defense builds, the components and the work around them usually outweigh the placement itself.
There is no public price list for aerospace PCB assembly, and we will not invent one. This guide explains each cost driver, why it moves the price and what the buyer controls, with the few public figures we could verify. For what to put on the order, see our PCB assembly sourcing page; this page is about the money.
How an assembly quote is built
Assemblers price from the bill of materials, the assembly drawing and the placement data, and they split the quote into one-time charges and per-board charges. Knowing the blocks lets you compare quotes line by line.
- Bare board: bought by the assembler or supplied by you, priced on class, layers, material and features.
- Components: every BOM line at the quantity needed plus attrition, from the sources your rules allow.
- Sourcing controls: traceability records, and inspection or testing for any part from outside authorized channels.
- Nonrecurring engineering: data review, placement programs, stencils, fixtures, test programs and first article.
- Assembly: surface mount placement and reflow, through hole and hand soldering, rework.
- Inspection: AOI, X-ray, visual inspection to the class you name.
- Coating: cleaning, masking, coating, cure and inspection.
- Test: in-circuit or flying probe, functional test, environmental stress screening.
- Documentation: traveler, parts traceability, test data, first article report and certificate of conformance.
Cost drivers at a glance
The table lists the drivers that move a PCBA quote most, with the lever a buyer holds for each. The sections after it go deeper.
| Driver | Why it moves cost | How the buyer controls it |
|---|---|---|
| Bare board class and layers | More layers, blind and buried vias, Class 3 and the space addendum add fabrication steps, coupons and testing | Use the class and stackup the product needs; avoid blind and buried vias unless density demands them |
| Turnkey versus consigned parts | Turnkey prices in the assembler's buying, handling and risk; consigned shifts shortages and kit errors to you | Pick the model per BOM line and write down who owns shortages and excess |
| EEE part grade | Space and full military grades cost far more than commercial parts and often have long factory lead times | Assign the grade per line from your parts plan, not one grade for every part |
| Counterfeit screening | Parts from outside authorized channels need inspection and lab testing before use | Buy from manufacturers and authorized distributors first; decide early who approves anything else |
| Setup and stencils | Programs, stencils, feeder setup and first article are paid once per build or revision | Build in fewer, larger lots and avoid revision changes between lots |
| Placement count and fine pitch or BGA | More placements, smaller parts and hidden joint packages take more machine time, inspection and rework | Remove unused parts, and choose packages your reliability and inspection plan can support |
| X-ray | Hidden joints under BGAs and bottom terminated parts can only be checked by X-ray or CT | State the parts, the acceptance criteria and the sampling plan |
| Conformal coat and masking | Cleaning, masking every connector and test point, coating, cure and inspection are mostly hand work | Minimize keep-out areas, group connectors, and name one coating type and thickness |
| Functional test and ESS | Test fixtures, procedures and thermal or vibration screening take equipment time on every unit | Supply the procedure and fixture, and set the ESS profile to what the program actually requires |
| Documentation and FAI | Serialized records, parts traceability and an AS9102 first article take quality hours | Require a full FAI where needed and a partial one after small changes |
| Quantity | One-time costs are spread over the lot, and component price breaks depend on quantity | Quote two or three quantities and buy long lead parts for the program, not the lot |
Bare board class and layer count
The bare board can be a large share of a low volume assembly, and its price follows its construction more than its size. Layer count, via structure, material, the IPC-6012 class and any space addendum decide how many fabrication steps and how much verification the board needs.
- Layers. Each added layer pair means more inner layer imaging, etching, inspection and lamination, and more holes to drill and plate.
- Blind and buried vias. Usually require sequential lamination, which repeats press cycles and drilling. They save space but cost money on every panel.
- Material. High Tg FR-4 and polyimide laminates cost more than standard FR-4, and some fabricators run them less often.
- Class 3 and the addendum. Tighter acceptance, coupons with microsection reports, and fewer qualified fabricators. Under the military specification route, boards can be bought to MIL-PRF-31032 from manufacturers listed on QML-31032.
- Panel use. Small lots of an odd sized board can carry the cost of a mostly empty production panel.
Board prices have also moved sharply. On the Producer Price Index for bare printed circuit board manufacturing, published by the Bureau of Labor Statistics and charted by FRED, the index rose about 45 percent between August 2025 and August 2026, with recent months still preliminary. That is an industry index, not an aerospace board price, but it explains why a requote on an old design can surprise. Our printed circuit boards page covers classes, laminates and coupons in detail.
Component sourcing: turnkey versus consigned
Who buys the parts changes the price, the risk and the schedule. Turnkey builds cost more on paper because the assembler prices in its purchasing labor, handling, attrition and the risk of shortages; consigned builds look cheaper but move those costs and risks to you.
In a turnkey quote, check:
- Which sources the assembler may use, and whether alternates are allowed per line.
- How attrition for small passives and reels is priced, and who owns excess parts and partial reels after the build.
- Whether minimum order quantities on some lines inflate the price of a small lot.
In a consigned build, the hidden costs are kit errors and shortages: one missing line stops the build, and the assembler may charge to restart. Moisture sensitive parts shipped outside dry packs may need baking. Partial consignment, where you supply critical or screened parts and the assembler buys commodity parts, is often the cheapest total for flight and defense work, as long as the BOM is split clearly by line. Our kitting and BOM sourcing pages cover how complete kits are built.
EEE part grade
Component grade is often the single biggest swing in an aerospace assembly price. The same function can be bought as a commercial part, an automotive qualified part, a military class part or a space class part, and each step up adds screening, qualification and lot data that the price reflects.
NASA-STD-8739.10, NASA's EEE parts assurance standard, sorts parts into four grades and lists the military classes that typically meet each, such as JANS, JANTXV and JANTX for discrete semiconductors under MIL-PRF-19500 and Class V and Class Q for microcircuits under MIL-PRF-38535. Higher grade parts are made in smaller volumes, are often built to order, and can carry factory lead times that set the schedule for the whole assembly.
The costly mistake is applying the highest grade to every line. Passive parts in non critical circuits, test points and GSE boards may not need the grade a flight processor needs. Assign the grade per line from your parts plan, and record which lines have no acceptable source so the gap is found before the build, not during it. Our EEE parts grades page explains the classes, and the integrated circuits and discretes and passive components pages cover ordering each family.
Counterfeit screening
Buying from the original manufacturer or its authorized distributors costs the least in screening, and any part from outside that channel adds inspection and lab testing to the price. On defense work, DFARS 252.246-7008 sets the order of sources and requires inspection, testing and authentication for parts from other sources; our PCB assembly page walks through the clause.
The reason the screening exists is not theoretical. In GAO-12-375, published in February 2012, GAO requested military grade electronic parts on internet purchasing platforms, and all 12 parts requested by rare part number or post production date code that it had tested were rated suspect counterfeit by an independent lab. GAO also bought four parts requested under invalid part numbers, showing vendors would supply parts that do not exist. GAO noted its sample was not generalizable.
What screening costs depends on the plan. SAE AS6171 standardizes test methods for suspect counterfeit parts, with specific methods in slash sheets such as X-ray fluorescence, delid and decapsulation, and electrical test. Some of those methods destroy samples, so a small lot of an expensive part can lose a meaningful share to testing. Testing also adds lab queue time, and SAE is clear that no amount of testing proves a part authentic. The cheapest path is to design with parts in production, buy long lead and end of life parts early, and decide in writing who may approve a non-authorized source before the assembler needs it. See counterfeit parts avoidance and the obsolete parts cost guide.
Setup and stencils
Setup is a fixed cost per build or revision, which is why the first few boards of a lot cost far more than the rest. It covers the work done before the first part is placed.
- Data review. Checking the BOM, centroid, Gerber or ODB++ data and drawing against each other, and resolving questions.
- Programs. Pick and place programs, AOI programs and reflow profiling for the board's thermal mass.
- Stencils. A solder paste stencil per board side, and a step stencil when fine pitch parts and large connectors need different paste volumes. A design change that moves pads usually means a new stencil.
- Feeder setup. Loading every reel, tube and tray on the line, which takes longer on a BOM with many unique lines than on one with many placements of a few parts.
- First article. Building and inspecting the first board before the rest run.
Buyers control setup cost by building fewer, larger lots, avoiding revision changes between lots, and consolidating BOM lines where engineering allows. Line count often matters more to setup time than placement count.
Placement count, fine pitch and BGA
Placement cost rises with the number of parts, and it rises faster for small, fine pitch and hidden joint packages. Machine placement of standard parts is quick; the cost lies in the packages that need tighter process control, inspection and rework.
- Placement count. More parts mean more machine time and more for AOI and inspectors to check.
- Through hole and hand soldering. Connectors, transformers and large parts soldered by hand or selective solder cost more per joint than reflowed surface mount parts, and they bring their own inspection.
- Fine pitch and very small passives. Need precise paste printing and placement, and are harder to inspect and rework.
- BGA, LGA and bottom terminated parts. Joints are hidden, so they need X-ray, careful profiling and, if a defect is found, rework with specialized equipment and reballing or replacement parts. IPC-7095 is IPC's guidance on BGA design and assembly.
- Double sided assembly. Adds a second print and reflow pass.
Remove parts that are never populated, avoid mixing many package styles without a reason, and choose packages your inspection plan can verify. If a design uses a BGA only for its footprint, a leaded package may cost less to build and inspect, provided it meets the electrical and reliability needs.
X-ray inspection
X-ray is the only practical way to check solder joints you cannot see, so any BGA, LGA or QFN on the board adds X-ray time to the price. The cost depends on how many parts need it, whether every board or a sample is checked, and whether 2D X-ray is enough or 3D computed tomography is required.
Voiding acceptance limits differ by document and revision, and by how voids are measured, so a quote that does not know your criteria has to guess. Write down which parts need X-ray, the acceptance standard and class, the sampling plan for production boards, and whether images are delivered. First article boards normally get full X-ray with images; production lots may be sampled when the process is stable and your contract allows it. Rejected joints mean rework and reinspection, which is why reflow profiling on the first article is worth paying for.
Conformal coating and masking
Coating is mostly hand labor, and masking is usually the largest part of it. The coating material itself is a small share of the cost.
Before coating, the assembly is cleaned and dried, since coating over contamination traps it. Then every area that must stay uncoated, such as connectors, test points, adjustable parts, grounding pads and heat sink contact areas, is masked with boots, tape or masking compound. After coating and cure, masks are removed and the coating is inspected, often under ultraviolet light when the material carries a tracer, and thickness is checked.
What raises the price:
- Many small keep-out areas scattered across the board.
- Coating types that need long cures, or parylene, which is vapor deposited in a vacuum chamber, often at a specialist shop.
- Tight thickness limits that need measurement on every board.
- Coating removal and recoat after rework.
Group connectors and keep-out areas during layout, name one coating type and thickness range on the drawing, and decide whether boards are coated before or after functional test. On NASA hardware, NASA-STD-8739.1 governs coating workmanship. Our conformal coating reference covers the types and limits.
Functional test and ESS
Test is a fixed cost to set up and a smaller cost per unit, except for environmental stress screening, which costs chamber time on every unit. Who supplies the test procedure and fixture changes the quote more than anything else here.
- Flying probe or in-circuit test. Flying probe needs no dedicated fixture, so it suits small lots; a bed of nails fixture costs more up front and less per board at volume.
- Functional test. Powers the board and runs your procedure. If the assembler must write the procedure or build the fixture, that is engineering work and should be its own line. If you supply them, say so on the RFQ.
- Environmental stress screening. Thermal cycling and random vibration on every unit to expose latent defects. The profile, number of cycles and failure-free period set chamber time. MIL-HDBK-344A covers ESS of electronic equipment, though many programs define profiles in their own documents.
Set the ESS profile to what the program requires, not the harshest one on file, and give one test specification with limits and data requirements. Qualification testing of a design, such as thermal vacuum or shock, is a separate lab job; the environmental test lab cost guide explains how that is priced.
Documentation and first article
Records are real labor on aerospace assemblies, and the first board of a new part number or revision carries most of it. An AS9102 first article report covers the design characteristics plus material and process records, which on an assembly includes parts traceability for every BOM line.
Per-unit records add cost too: a traveler with operator and inspector stamps, manufacturer, part number, lot or date code and source per BOM line tied to the serial number, moisture sensitive device and bake records, inspection results, X-ray images, test data and the certificate of conformance. Customer source inspection adds scheduling and time.
Match the records to the contract. Ask for a full first article for a new source or revision and a partial one after a small change, and use your own forms only where the contract requires them. Our first article inspection guide and certificate of conformance page cover what each should contain.
Quantity
Quantity spreads every one-time cost: data review, programs, stencils, test fixtures and programs, and the first article. It also sets the price breaks on components, where buying 10 of a part can cost nearly as much as buying 50 once minimums and reels are counted.
Ask for two or three quantities to see how much of the unit price is setup. Where a program needs more boards over time, buy the long lead and graded parts for the whole program up front and build in scheduled lots, so later lots do not wait on a factory lead time or face a part that has gone end of life. Store the program buy under controlled conditions, with moisture sensitive parts kept in dry packs.
Public numbers worth knowing
A few government figures help explain assembly pricing, though none is a board price or a shop rate. Producer price index values are from the Bureau of Labor Statistics as charted by FRED; recent months are preliminary and can be revised.
| Figure | What it shows | Source |
|---|---|---|
| PPI, bare printed circuit board manufacturing: up about 45 percent, August 2025 to August 2026 | A sharp rise in bare board prices across the industry | BLS via FRED, series PCU334412334412 |
| PPI, semiconductor and related device manufacturing: down about 3 percent over the same months | Broad semiconductor prices did not move with boards; graded and obsolete parts follow their own market | BLS via FRED, series PCU334413334413 |
| Median annual wage, electrical, electronic and electromechanical assemblers: $45,850 (May 2025) | Pay for the occupation that builds assemblies | BLS Occupational Outlook Handbook |
| Median annual wage for assemblers and fabricators in computer and electronic product manufacturing: $45,540 (May 2025) | Pay across the whole assembler group in that industry | BLS Occupational Outlook Handbook |
| Median annual wage, quality control inspectors: $48,570 (May 2025) | Pay for the inspection labor behind visual, AOI and X-ray review | BLS Occupational Outlook Handbook |
| GAO-12-375 (February 2012): all 12 tested parts requested by rare part number or post production date code rated suspect counterfeit | Why open market parts carry screening cost | U.S. Government Accountability Office |
A shop's billed rate is well above these wages because it also covers placement lines, reflow ovens, AOI and X-ray systems, test equipment, ESD controlled areas, training, quality staff and profit. We found no neutral published survey of aerospace PCBA prices or rates, so compare complete quotes on the same package.
Ways to lower PCBA cost without lowering quality
- Send a complete package: drawing at revision, BOM with approved manufacturers and alternates, placement data and the bare board source. The RFQ builder structures it.
- Assign workmanship class and part grade per assembly and per BOM line, not per program.
- Buy long lead and graded parts for the program early, from authorized sources.
- Choose turnkey, consigned or partial consignment per line and write down who owns shortages and excess.
- Avoid blind and buried vias, hidden joint packages and scattered keep-out areas unless the design needs them.
- Supply the functional test procedure and fixture, and set ESS to what the program requires.
- Ask for board, parts, setup, assembly, inspection, coating, test and documentation as separate lines.
If cables terminate on the board, the wire harness cost guide covers that side, and the composites cost guide covers the panels many assemblies mount to.

Questions
How much does aerospace PCB assembly cost?
There is no public price list, and two boards of the same size can differ in price many times over. A Class 2 test board with commercial parts and no coating costs far less than a flight card with space grade parts, Class 3 and the space addendum, X-ray on every BGA, conformal coating, ESS and a full first article. Send the BOM with grades, the class, the test plan and the quantity so every quote covers the same scope.
Is turnkey or consigned PCB assembly cheaper?
Consigned builds usually look cheaper on the quote because the assembler is not buying parts, but you carry shortages, kit errors, attrition and counterfeit risk. Turnkey builds price those in and make one party accountable. For flight and defense work, partial consignment is common: you supply screened or long lead parts, the assembler buys commodity parts. Compare total cost, including your own purchasing and kitting time.
Why are my first boards so much more expensive than later ones?
The first lot carries the one-time costs: data review, placement and AOI programs, stencils, reflow profiling, test programs and fixtures, and the first article report. Later lots at the same revision reuse most of that. Quote two or three quantities to see the setup share, and avoid design changes between lots, since moved pads mean a new stencil and changed parts mean new programs.
How much does counterfeit screening add to a board?
Nothing beyond normal records if every part comes from the manufacturer or its authorized distributors. Parts from other sources need inspection and lab testing under a plan such as SAE AS6171, which can include destructive methods that consume samples and add lab queue time. The cost is per part number and lot, so it weighs most on small lots of expensive parts. Buying early from authorized sources is usually cheaper.
Do I need X-ray on every board?
X-ray is needed wherever joints are hidden, such as BGAs, LGAs and QFNs. First article boards normally get full X-ray with images. For production, many programs allow a sampling plan once the process is stable, but some flight contracts require every board. Write down which parts need X-ray, the acceptance criteria and the sampling plan, so quotes do not pad for the worst case or leave it out.
Why did my bare board price go up so much?
Industry prices rose sharply. The Producer Price Index for bare printed circuit board manufacturing, published by the Bureau of Labor Statistics and charted by FRED, rose about 45 percent from August 2025 to August 2026, with recent months preliminary. A requote on an older design reflects current fabrication costs, and Class 3, the space addendum, extra layers and sequential lamination all add to that base.
