Project Documentation & Batch Traceability
Project Documentation & Batch Traceability
Samples, inspections, and batches stay tied to the same drawing revision.
For programs that switch revisions, replace legacy parts, or trace issues back to a specific batch, the hardest part is keeping drawings, samples, inspection records, and batch labels in step. We anchor all four to one controlled drawing, so re-orders and after-sales traceability stay on a single source of truth.
Capability scope
Best fit for projects with connectors already chosen and either a starting drawing or a physical sample — every later sample, inspection, and batch maps back to one defined revision.
Drawings, samples, inspections, and batches all tied to the same revision
Applies to display interconnect, medical device, FFC/FPC, IDC, LVDS, and micro-coax cable projects
Suits revision switches, repeat orders, and after-sales traceability
Record formats and acceptance criteria follow the quality documents both sides agree on
Process Flow
| Step | Station / Action | Control Point | Output Record |
|---|---|---|---|
| Input review | Drawing, sample-confirmation requirements, OQC items, batch label rules, shipment document requirements | Confirm coverage of the current project revision boundary | Input review record |
| Drawing control | Archive current revision + bind version number | Interface references / pin definition / routing notes / bend zones match the same revision | Controlled drawing record |
| Sample confirmation | Sample / key test results / customer confirmation comments | Sample matched to revision + batch binding | Sample confirmation record |
| OQC inspection | Sample / pre-shipment batch OQC | Executed per customer-defined inspection items | OQC inspection report |
| Batch binding | Pre-shipment batch labels + carton marks | Batch number bound to drawing revision / sample confirmation number | Batch label / carton mark |
| Shipment traceability | Shipment documents + COC | Documents return to the same revision | COC + shipment documents |
Inspection Checkpoints
| Checkpoint | What is checked | Record | Limit |
|---|---|---|---|
| Incoming / sample match | Interface model / pin / routing / appearance | Incoming record or sample photos | Customer-supplied part standards confirmed in advance |
| In-process check | Key dimensions / termination / routing / marking | Sampling table / inspection record | Sampling ratio per project definition |
| Pre-shipment confirmation | Labels / packaging / documents | Carton marks and shipment record | Special documents agreed in advance |
Deliverable Records
| Deliverable Record | Stage | Use | Limit |
|---|---|---|---|
| Sample confirmation record | Sample stage | Locking the release boundary | Platform changes require re-confirmation |
| Inspection report | Sample / production | Evidence of key inspection items | Inspection content per project definition |
| FAI | First article / pilot | Aligning first-article structure and dimensions | Needs customer-confirmed standard |
| COC | Batch shipment | Batch release | Not equivalent to third-party certification |
| Batch label / carton mark | Production | After-sales traceability | Must correspond to order / shipment records |
| Controlled drawing | Ongoing | Revision traceback | Customer drawing IP owned by the customer |
Applicable Projects
Representative fit scenarios:
Revision drawings + interface records for multi-version display projects (eDP 30-pin / 40-pin, LVDS 20-50-pin, etc.)
Controlled pin-sequence and labeling-rule records for patient monitoring / diagnostic equipment
Controlled pitch and structure records for ribbon IDC / FFC-FPC
End / shield process records for micro-coax projects
Related Applications
These application families and child pages often involve drawing revisions, sample approvals, OQC records, batch labels, or shipment-side file matching. Use them to enter the specific product direction, then confirm record format, inspection items, and traceability boundaries against the real project.

FAQ
- Does your COC count as a third-party certificate?
- No. The COC is EDPcable's own batch release statement showing the batch matches the agreed project documents. For IPC, ISO, or similar third-party certificates, see the dedicated capability pages.
- We don't have the original drawing — can you still help?
- Yes. We can derive a controlled drawing from a physical sample and key dimensions; both sides confirm it before production batches reference it.
- Can the batch label format follow our internal system?
- Yes. Label content, layout, and scan-code format follow what you specify; the labeling rules need to be locked in during the project setup stage.
- What does the OQC report cover?
- Whatever inspection items you define. The default set covers continuity, short/open, key dimensions, and visual checks; special items should be agreed upfront.
