Pyralux LF9110R: Acrylic Flex Construction and Cost
Pyralux LF9110R is a single-sided adhesive-based flex laminate. Manufacturer data lists 35 碌m RA copper, 25 碌m acrylic adhesive and 25 碌m polyimide. This page helps compare complete construction and cost scope, especially when a simplified quote has omitted the adhesive or treated LF as an adhesiveless product.
Count the material that is actually supplied
The three rounded thickness entries total 85 碌m before later layers. That dimension describes the incoming construction, not the finished circuit at every location. Coverlay, contact finish, plated features and reinforcement can change local thickness. Keep those additions visible in the section used for a connector or enclosure fit check.
Construction and decision boundaries
| Review item | What this page establishes | What remains project-specific |
|---|---|---|
| LF9110R | Copper / acrylic adhesive / PI | Three constituents before covering. |
| Design tool | Region thickness and interval | Use the connector measurement basis. |
| Cost tool | Visitor-entered allowances | No embedded material prices. |
Distinguish a material price from a board price
The fabricated part includes imaging, patterning, covering, profiling, inspection and delivery format. Assembly support or unusual contact geometry may add further work. A material-only quote cannot establish the cost of the finished requirement. Compare like-for-like drawings and accepted quantities rather than assuming every adhesive flex has a fixed discount against every adhesiveless flex.
| Review item | What to establish |
|---|---|
| Construction | Include the acrylic bonding layer |
| Dimensions | Local section and measurement point |
| Commercial | Same accepted quantity and manufacturing scope |
| Limit | Entered allowances are not current market prices |
Use two different worksheets for two decisions
The thickness worksheet organizes the section and its tolerance interval. The optional allowance worksheet compares amounts entered by the visitor from a quote or labeled assumption. It does not contain market rates. Do not use a favorable cost output to approve a stack that has not passed the dimensional and process review.

Use the current inputs and keep the assumptions
Start with the example only to inspect the units and the calculation boundary. Replace every assumption with a value tied to your own document or measurement. An empty numeric field is not zero. The review-reference field is a local label; avoid entering customer names, confidential part numbers or other private information into a public worksheet.
After calculating, read the notes alongside the numerical result. Changing any input invalidates the displayed result and disables its download until you calculate again. For a comparison, keep the units, geometry, material condition and measurement boundary consistent. A long decimal result does not imply equally precise input data. The downloadable record stays on your device and can be attached manually to an inquiry. It is not automatically transferred into the Contact form.
If an input is unknown, identify the person or document needed to resolve it. Do not fill a gap with a favorable generic value simply to obtain a result. You can request a material or fabrication review without using the tool. The arithmetic illustrates a relationship; it does not accept a construction, certify a material, establish current pricing or replace a supplier process specification.
| Input | What to establish before using it |
|---|---|
| Review reference | Nonconfidential revision label. |
| Layer entries 路 CSV | All dimensions in mm. Use each physical thickness once. Minus and Plus are positive absolute deviations, not percentages. |
Optional cost comparison from your own allowances
Use a quotation or a clearly labeled internal assumption for each input. Keep the quantity, construction and inspection scope the same when comparing alternatives. This uncalibrated planning model adds entered values; it contains no current market rates and does not issue a 吃瓜tv quotation. You can contact the team without completing it.
Optional project allowance comparison
Compare the next plausible construction
FR9110R brings a flame-retardant material-system requirement into the comparison. LF9120R changes the polyimide gauge. AC182500 is single-sided adhesiveless material with different foil and no intermediate acrylic layer. Identify the property or manufacturing constraint that motivates a change before asking the supplier to price it.
Keep local support and covering explicit
The same part may have an unsupported flexible arm and a reinforced connector end. Show the coverlay and stiffener boundaries against the contact datum. Assembly handling should not depend on an unstated extra layer. Confirm where the finished thickness is inspected and whether the delivered form is an individual circuit or retained panel.
Prepare a comparable RFQ
Provide the complete LF code, regional stack, outline, copper pattern, contacts, quantity and test scope. Ask for one-time items separately and identify permitted alternatives. If the drawing is incomplete, list the questions that need engineering input. That creates a practical route to a useful quote without pretending that a material name alone fixes the cost.
Compare quotations on the same adhesive-based build
| Review point | Input to record | Decision or verification |
|---|---|---|
| Construction | List the supplied copper, adhesive and film before adding coverlay or stiffeners. | Keep incoming laminate cost distinct from fabrication operations. |
| Commercial boundary | Separate one-time tooling, recurring fabrication and any assembly support. | Compare quotes at the same quantity, delivery format and acceptance scope. |
| Alternative | State which layers, contacts and dimensional requirements may change. | Do not compare a single-sided adhesive construction with a double-sided core as if they were identical. |
Use the review points above alongside the worked example on this page. Record the chosen inputs with the drawing revision and send unresolved items with the enquiry. A supplier response should identify the proposed construction and the evidence needed for release.
Standards, source context and limits
Use the edition, amendment and material-document revision named in the purchase agreement. A standards title, marketing label or supplier product family does not establish that a particular lot meets a requirement. Public summaries are useful for scope; the controlled specification and applicable test method govern acceptance.
The examples on this page are illustrative engineering scenarios. They are not 吃瓜tv production records or guaranteed material values. Source links identify the organizations responsible for the referenced information. Confirm applicability to the exact grade, construction and test condition before carrying a number into a drawing or qualification report. For a flex board, distinguish the design requirements in IPC-2223, finished-board qualification and performance in IPC-6013, and the material scopes of IPC-4202, IPC-4203 and IPC-4204. These cover different deliverables; naming them does not certify the material or factory. State the contracted revision and applicable material sheet. Source review date: 3 October 2026. Legacy designation, present availability and an approved replacement are separate questions.
