ETECKSPACEQUICK ANSWER
Minimum viable RFQ: drawing, material target, volume, and timing
A product name or screenshot rarely identifies the structure and quality scope. Provide at least a controlled drawing, material or performance target, sample and production volume, application and assembly method, test needs, and target timing. Confirm an NDA or controlled exchange before sending confidential drawings.
REVIEW FRAMEWORK
Ten-item HTCC RFQ checklist
Project and contacts
Project code, organization, engineering contact, procurement contact, and response deadline.
Drawing revision
2D/3D file names, revision, release date, units, and applicable supporting specifications.
Material and performance
Specified material, acceptable alternatives, or the electrical, thermal, mechanical, and environmental targets.
Structure and stack-up
Outline, thickness, layers, cavities, steps, vias, conductors, and critical dimensions.
Tolerances and key features
Separate standard dimensions from critical characteristics and provide datums, measurement methods, or mating interfaces.
Metallization and plating
Define zones, system or functional purpose, plus bonding, soldering, brazing, and sealing requirements.
Sample and production volume
List engineering samples, validation lots, and expected production volume separately.
Quality and testing
State the scope and acceptance basis for appearance, dimensions, continuity, adhesion, plating, hermeticity, reliability, or third-party records.
Packaging and logistics
Define cleanliness, moisture or tarnish protection, trays, labels, lot traceability, and delivery region.
Schedule and commercial terms
Target sample date, production window, quote currency, trade terms, and costs that should be separated.
WORKING CHECKLIST
Quick completeness check before sending an RFQ
Use this table to decide whether the request is ready for supply feasibility review.
| Status | Decision basis | Next action |
|---|---|---|
| Initial review ready | Application, outline or sample, material target, and approximate volume are available | Identify missing fields and assess a possible process direction |
| Formal RFQ ready | Controlled drawing, key specifications, volume, test, packaging, and timing are available | Issue one consistent RFQ to matched resources |
| More information needed | Only a product name, image, or uncontrolled legacy file is available | Clarify the drawing and requirement before requesting prices |
| Controlled exchange needed | Files include client-confidential circuits, personal data, or controlled information | Confirm NDA, permissions, and a compliant exchange method first |
RISK BOUNDARY
Gaps most likely to cause requotation
- Drawing revisions change without identification
- Sample and production volumes are combined
- Metallization zones and plating purpose are unclear
- Critical tolerances have no measurement basis
- Test-record requirements appear only after quotation
FAQ
Questions before the next review step
Can I request a quote without a final drawing?
You can request directional feedback, but it should be treated as non-binding. Final price, timing, and quality scope need a controlled revision.
How should confidential drawings be submitted?
Send a redacted summary first and confirm NDA, permissions, and a controlled exchange method through sales@eteckspace.com.
Can sourcing rely on a reference sample only?
A sample helps communicate structure, but material, dimensions, tolerances, metallization, testing, volume, and intellectual-property boundaries still need confirmation.
