Folientastatur-RFQ-Checkliste
A strong membrane switch RFQ should include Zeichnungs, Druckdaten, Abmessungen, quantity, circuit or pinout, connector details, material preferences, adhesive surface, application environment, compliance needs, and sample expectations.
You can start with partial information, but clearer details reduce back-and-forth and help JASPER recommend a practical structure faster.
Quick answer: send the files that define fit, function, appearance, and risk.
Eine gute RFQ braucht am ersten Tag nicht jede finale Produktionsdatei, sollte aber erklaeren, was das Teil ist, wo es sitzt, wie es verbunden wird, wie es genutzt wird, was es aushalten muss und welche Qualitaets- oder Compliance-Anforderungen wichtig sind.
Basic information to include in a membrane switch RFQ
These details help a supplier quote the same part you actually need, not a guessed version of it.
| Information | Examples | Why it matters |
|---|---|---|
| Product type | Membrane switch, keypad, graphic overlay, control panel | Defines whether the request is an electrical switch assembly or only a printed surface |
| Drawing | PDF, DXF, STEP, Gerber, marked sketch | Controls outline, holes, windows, thickness, tolerance, and fit |
| Artwork | AI, PDF, Pantone references, legend notes | Defines colors, icons, text, windows, dead-front graphics, and revisions |
| Quantity | Prototype, first order, annual forecast | Affects process choice, tooling, unit cost, and production planning |
| Function | Key layout, circuit, pinout, LED positions | Defines electrical behavior and test requirements |
| Connector | Tail length, pitch, ZIF/crimp/header, contact side | Prevents assembly failure after the sample works electrically |
| Application | Industrial, medical, appliance, marine, instrument | Helps review environment, user behavior, and risk points |
| Environment | Indoor, outdoor, moisture, cleaning, chemicals, UV | Guides material, adhesive, sealing, and testing |
| Compliance | RoHS, REACH, UL-rated material options, documentation | Must be reviewed before material selection, not after sampling |
Details that make the quotation more accurate
These items are not always available at first contact, but they reduce engineering assumptions.
| Detail | Useful examples | What it helps decide |
|---|---|---|
| Enclosure photos or Zeichnungs | Front panel, mounting area, ribs, screw bosses, display window | Adhesive, tail exit, gasket, and assembly fit |
| Existing sample or failed part | Physical sample, photos, known supplier issue | Reverse engineering, failure prevention, structure comparison |
| Target key feel | Tactile, non-tactile, dome force, sample preference | Dome selection, spacer design, actuation review |
| Display or LED windows | Clear, tinted, smoked, dead-front, LED color | Window material, opacity, light leakage, dust control |
| Adhesive surface | ABS, PC, metal, powder coat, texture, paint | Rear adhesive choice and bonding risk |
| Packaging requirements | Flat pack, protective film, export carton, label | Cosmetic protection and shipment handling |
| Quality records | Continuity, short/open, visual, dimensional, sample report | Inspection scope and buyer documentation |
Information gaps that slow down quotations
These gaps often create extra email rounds or quotes that are not comparable.
| Missing detail | Was passiert | How to avoid it |
|---|---|---|
| No connector information | Tail and pinout are guessed | Send connector datasheet, pitch, pin count, contact side, and pinout |
| Only Druckdaten is provided | Electrical function and stack are unclear | Add circuit, key functions, tail route, and enclosure notes |
| No environment description | Material and adhesive risk is unknown | State cleaning, water, UV, temperature, chemicals, and indoor/outdoor use |
| No quantity range | Prototype and production pricing cannot be planned | Send sample quantity, first order, and annual estimate if possible |
| No enclosure data | Fit, adhesive, sealing, and tail exit are guessed | Send housing Zeichnung, photos, or mounting surface notes |
| Unclear revision control | Wrong Druckdaten or old layout may be quoted | Mark file revision, date, and which file is current |
Start with what you have, then close the gaps deliberately.
A strong RFQ is not about perfect paperwork. It is about reducing assumptions that affect cost, lead time, tooling, sample approval, and production quality.
- Separate “must-have” requirements from preferences that can be optimized.
- Share the real application environment early; material and adhesive choices depend on it.
- If the connector is not final, say so and ask for practical options.
- If the part replaces an existing supplier product, send the sample and known problems.
- If there are regulatory or customer documentation needs, define them before material selection.
- Use one current Druckdaten/Zeichnung revision and avoid sending conflicting file versions.
RFQ note: If you are unsure, send the Zeichnung, Druckdaten, photos, quantity, use environment, connector notes, and questions. JASPER can identify what is missing before quoting final production.
How JASPER uses RFQ information
The same checklist supports engineering review, purchasing comparison, sample planning, and production risk control.
Technische Pruefung
Layer stack, circuit, connector, lighting, waterproofing, and adhesive risks can be reviewed before tooling.
Quotation accuracy
Clear quantity, structure, and documentation needs reduce broad assumptions in pricing.
Sample planning
The team can decide what must be validated in the first sample: fit, feel, lighting, sealing, or connector routing.
Material selection
Overlay film, adhesive, spacer, dome, circuit, and compliance options can be matched to the environment.
Inspection scope
Continuity, visual, dimensional, actuation, adhesion, and packaging checks can be defined by project need.
Supplier comparison
Eine vollstaendige RFQ erleichtert den Angebotsvergleich, weil Lieferanten auf dieselben Anforderungen antworten.

Membrane switch RFQ questions
Kann ich ohne Gerber-Dateien ein Angebot anfordern?
Yes. Drawings, Druckdaten, sketches, photos, and samples can start the discussion. Gerber files help when circuit details are already defined, but they are not always required at the first RFQ stage.
What if I do not know the material?
JASPER can recommend material options after reviewing the application, environment, cleaning exposure, appearance target, and compliance needs.
Can you quote several structure options?
Yes. For uncertain projects, JASPER can compare practical structure options such as tactile vs non-tactile, PET vs PC, connector choices, lighting options, or sealing approaches.
What is the most important RFQ file?
The most useful starting point is usually a Zeichnung or marked sketch plus Druckdaten and application notes. Connector and enclosure information are also very important.
Can I send a physical sample?
Yes. A physical sample can help confirm thickness, structure, key feel, connector, adhesive, material, and previous supplier issues.
Should I include Jahresmenge?
Yes. Prototype quantity, first order, and annual forecast help choose a practical manufacturing and pricing route.
Can JASPER help complete missing details?
Yes. JASPER can identify missing connector, material, tail, adhesive, lighting, or testing information during RFQ review.
Do compliance requirements affect the quotation?
Yes. RoHS, REACH, UL-rated material options, or customer documentation requirements should be stated early because they affect material selection and records.
