Match the document to the decision
IPC-2223 addresses flexible and rigid-flex design; IPC-6013 addresses qualification and performance of flexible printed boards. Select applicable acceptance and assembly documents with the responsible customer and supplier. Connect these choices to the fabrication drawing. A topic preview or revision listing identifies scope and editions, but does not provide the complete criteria needed to assess compliance.
Requirements by purpose
| Investigation item | Question | Evidence to retain |
|---|---|---|
| Design | Which rules guide construction and layout? | Applicable design document and revision |
| Performance | What must the finished board demonstrate? | Contracted performance requirements |
| Acceptance | How are observed conditions dispositioned? | Agreed acceptance basis and exceptions |
| Assembly | What governs populated joints and workmanship? | Applicable assembly requirements and scope |
Create a contractual requirement record
Record document titles and revisions, relevant class or product category, addenda, customer-specific requirements, and approved departures. Assign responsibility for resolving conflicts. Use the inspection plan to explain how critical requirements will be checked and reported. Do not let a later standard revision silently replace the edition actually reviewed for an existing design.
Ask for evidence tied to the delivered build
Identify which material records, inspections, tests, and reports demonstrate the agreed requirements. Separate a company’s certification claim from the acceptance evidence for a particular circuit. No certification or process capability is established by this website’s source links. Review the complete applicable documents with qualified owners before making a compliance statement or accepting an exception.
Before you release the design
- Write exact document identifiers and revisions.
- Agree class, addenda, and customer-specific requirements where applicable.
- Resolve conflicting notes before fabrication release.
- Request records that correspond to the agreed build and requirements.
Watch points
- A public table of contents cannot establish that an unseen clause is satisfied.
- Linking to a standard does not certify a supplier or product.
Practical questions
Should I always specify the newest revision?
Review the edition appropriate to the customer contract and qualification basis. Check the official register, then agree any migration rather than changing an established requirement automatically.
Is an IPC class label sufficient for an RFQ?
No. Identify the relevant documents, revisions, construction, acceptance details, tests, and reporting needs. The class is only part of a complete requirement set.
