Material data and construction choices
Antenna feed and radome-adjacent construction
The nominal process and design Dk values are separate references. Use the design model appropriate to the actual AD255C construction rather than substituting the process value because it appears more familiar. A radome, cover or nearby metal can alter an antenna even when the laminate is unchanged. Include those surrounding parts in system validation.
| Property | Supplier reference | Engineering meaning |
|---|---|---|
| Process Dk | 2.55+/-0.04 | Supplier process reference; use the original method and construction. |
| Design Dk | 2.60 | Separate modeling reference. Confirm applicability to the chosen geometry. |
| Typical Df | 0.0013 | Property-tool heading: 10 GHz; parenthetical values refer to 2.5 GHz. Check grade notes. |
| Typical thermal conductivity | 0.35 W/m繚K | Consult the grade source for direction and method; not a finished-board power rating. |
| Typical X / Y / Z CTE | 34 / 26 / 196 ppm/K | The source table states its temperature interval. Axis and conditions matter. |
| Material flammability reference | V-0 | Supplier material listing, not certification of a fabricated board or assembly. |
Source: and the . Values are material references; purchasing and finished-board acceptance need their own agreed specification.
RF engineering workbench
Use explicit construction inputs. Results can be downloaded or opened as an email draft; the tool does not upload project information.
Worked planning example
As a calculation example, use the published AD255C design reference Dk of 2.6, a 0.508 mm dielectric height and a 50 峏 target. The zero-thickness microstrip model gives approximately 1.407 mm trace width and effective permittivity 2.156. At 10 GHz, its guided wavelength is approximately 20.416 mm. The selected height and frequency are example inputs, not an assertion that this is an available or approved material construction.
Use the result to inspect scale and sensitivity. Preserve the input units and assumptions in the downloaded brief, then use the actual finished geometry and appropriate solver or measurement method for release.

Keep the material record tied to this construction
Label dielectric height, copper, reference planes and any bonding layer on the section. Attach the material source revision and the drawing revision to the same record. A changed foil or bonded structure needs a review of both the circuit model and fabrication route.
AD255C fabrication handoff: remove ambiguity before quoting
| Review point | Input to record | Decision or verification |
|---|---|---|
| Ordered construction | List grade, dielectric height, copper foil option and finished copper requirement. | Ask the supplier to mark any unavailable or proposed alternative item on the returned stack. |
| Panel and finish | Provide outline, array requirements, sensitive RF surfaces and finish boundaries. | Review handling, panel yield and RF contact needs before comparing a bare unit price. |
| Evidence supplied | State the inspection record, coupon requirements and agreed acceptance limits. | Match the delivered records to the drawing revision and manufacturing lot. |
A quotation for AD255C should identify the offered construction explicitly. Separate incoming copper foil from the finished conductor after processing. If the order has several antenna elements on a panel, include their position and the areas where tooling or profiling can affect the feed network. A material name alone does not describe a finished RF board.
For an antenna panel, define the RF verification boundary before procurement. The laminate supplier PIM test is a material-and-foil reference; the completed board, connectors and assembly introduce additional interfaces. If PIM is contractual, specify the completed test article, setup and reporting requirement instead of copying a laminate result onto the PCB purchase order.
Source review: . Resolve the document and construction used for release; typical values are not finished-board acceptance limits.
Cost planning and a direct RFQ route
Where the cost changes, and which savings are real
For a small RF order, setup, procurement and test preparation may matter as much as the area of laminate. A panel that holds more circuits spreads some shared effort across more boards, but only if the orientation, tooling and coupon requirements permit that layout. The budget tool uses an explicit rectangular nesting model so that its area assumption can be inspected. It does not assume every visible square millimeter of a panel becomes a delivered board.
Copper foil, core thickness and bonding system are part of the purchased construction. A quotation based on a different thickness or foil is not a clean price comparison, even when the headline material name matches. Ask whether the offered material is standard for the supplier's available construction and whether minimum purchases, special handling or qualification work affect the lot. Availability and lead time must be confirmed for the actual order rather than inferred from a web page.
Complexity can move cost in several directions. A hybrid stack may reduce the amount of premium RF laminate while adding press planning and interface review. Metal backing can improve a thermal path while adding bonding and machining requirements. Extra coupons or RF fixtures can reduce uncertainty but add material, setup and measurement work. Compare the complete project scope instead of ranking designs by laminate price alone.
The optional numerical budget uses cost allowances entered by the visitor. It contains no calibrated 勛圖tv tariff and does not claim current market pricing. The model combines the costed panels, one-time setup, batch testing and per-board processing; assembly is included only when selected and entered. Shipping, taxes, process yield loss and unentered qualification are excluded. A zero value means already included or deliberately zero, not unknown.
When geometry, quantity or supply scope changes, revisit the allowances. A per-board processing cost from one batch may not apply to another. The tool clears old allowances on those changes to avoid presenting a stale total. Hybrid, metal-backed, unresolved and more complex multilayer constructions go to engineering quotation. The downloaded brief remains useful because it carries the requirements and assumptions even when a numerical price would be misleading.

Verify the construction that matters to the product
A measurement plan that answers the design question
Begin with what the prototype must establish. Is the question electrical continuity, line impedance, insertion loss, phase balance, resonant frequency, thermal behavior or mechanical fit? These are different tests and they may require different coupons, fixtures and acceptance limits. A test label without the represented structure and measurement method leaves room for two parties to interpret the result differently.
For RF measurements, define the reference planes and account for the launch or fixture. A raw network-analyzer trace can include connectors and transitions that are not part of the material comparison. De-embedding or a representative reference structure may be needed, depending on the question. Record calibration, frequency span, temperature and the circuit revision with the result. This makes later comparisons more informative than a single unqualified pass statement.
Investigate a disagreement between the model and the board in a controlled sequence. Check the finished conductor dimensions, dielectric height, material construction and measurement setup before changing the Dk to force a fit. The model may omit a nearby cover, a return-path discontinuity or a loss mechanism. Equally, the test fixture may represent a different structure from the intended coupon. Identifying the cause protects the next build from an accidental compensation.
Keep the accepted construction and records together. A successful prototype supports the tested revision under its stated conditions. Changes to material, foil, bond system, geometry, assembly exposure or test scope deserve review before a repeat order is treated as equivalent. The project does not need every possible test; it needs the evidence that resolves its actual risks and acceptance requirements.

Questions before the next design or purchase decision
What should this page help me decide?
Define the material, finished RF construction and inspection scope for a fabrication quote. Start with the named construction and the relevant engineering requirement. The photographs show physical circuit examples, while the original-source links and explicit model assumptions support the technical review.
Which Dk should I enter for AD255C?
The supplier process reference is 2.55+/-0.04; the separate design reference is 2.60. Use the value and method appropriate to the actual construction and model. Effective permittivity is a line-geometry result, not a replacement label for either material value.
What is the most important construction detail here?
Exact AD255C core and foil. Keep that decision in the released drawing and ask the supplier to identify the offered construction explicitly. For this material, the follow-up verification should address antenna assembly environment.
Does the design tool approve this PCB for manufacture?
No. It calculates the stated preliminary model or organizes a construction brief. Finished copper, transitions, mixed dielectrics, assembly interfaces and process limits may require a more complete review. The downloaded result preserves assumptions so engineering can evaluate the same inputs.
Can I obtain a price without completing the tool?
Yes. Use the direct Contact or email route with your drawing, quantity and construction requirements. The optional budget uses your entered allowances and an explicit panel model; it is not a calibrated 勛圖tv tariff. Complex constructions need a file-based quotation.
What should I send with an enquiry?
Include the exact material designation, fabrication artwork, drill data, outline, proposed stackup, copper, finish and quantity. Add the relevant impedance, RF, thermal or mechanical acceptance requirements. If assembly is included, provide the BOM, placement data and test expectations.
