100% outgoing electrical test coverage
100% Electrical Testing for Cable Assemblies
Every shipped cable assembly passes the agreed continuity, short/open, and pin-sequence checks before release.
EDPcable performs outgoing electrical testing on cable assemblies before shipment, with continuity, short/open, and pin-sequence checks as the common baseline. "100%" means each assembly in the batch is tested against the agreed electrical test plan, not that every possible parameter is inspected. Tester models, covered test items, calibration evidence, and special test scope are confirmed during project review.
Capability scope
Best fit for programs where every shipped assembly needs an electrical pass record. Special tests such as hipot, insulation resistance, impedance, or signal integrity are reviewed case by case.
Each shipped assembly is electrically tested against the agreed project plan
Baseline coverage includes continuity, short/open, pin sequence, and basic connectivity
Batch summary records are standard; single-piece records can be agreed when needed
NCR handling and retest records connect to the ISO 9001 and IPC project quality path
Process Flow
| Step | Station / Action | Control Point | Output Record |
|---|---|---|---|
| Test plan review | Customer test item list / acceptance criteria | Mapped to equipment capability | Test plan confirmation |
| Test fixture prep | Project-specific test fixtures / jigs | Fixture matched to drawing revision | Fixture record |
| Equipment calibration | Periodic calibration of test equipment | Calibration within validity | Calibration record |
| In-process test | Sampling after termination / after assembly | Early detection of in-process issues | In-process test record |
| Pre-shipment 100% test | Every assembly tested to the project list | Per-piece result + batch summary | 100% electrical test report |
| NCR closure | Nonconformance classification / handling / retest | Handling time per customer requirement | NCR + handling record |
| Batch release | Batch electrical pass + COC | 100% electrical test coverage | COC + batch report |
Inspection Checkpoints
| Checkpoint | What is checked | Record | Limit |
|---|---|---|---|
| Equipment calibration | Tester accuracy / calibration validity | Calibration record | Cycle defined by the customer system |
| Fixture verification | Test fixture / jig structure | First-article check + sampling | Fixtures have limited life |
| Per-piece test | Each assembly against the test items | Per-piece record (as needed) + batch summary | Detailed per-piece records as agreed |
| Nonconformance NCR | NCR identification / isolation / handling | NCR record | Handling time per customer requirement |
Deliverable Records
| Deliverable Record | Stage | Use | Limit |
|---|---|---|---|
| Test plan confirmation | Early project | Locking test items / acceptance criteria | Does not replace the contract |
| Calibration record | Ongoing | Tester calibration evidence | Calibration certificates issued by third parties |
| Batch 100% electrical test report | Production | Batch coverage evidence | Detailed per-piece records as agreed |
| Per-piece test record (as needed) | Production | Customer internal audit / traceability | High data volume; sharing method agreed in advance |
| NCR + handling record | NCR | Nonconformance closure evidence | Handling method as mutually agreed |
| COC | Production | Batch release | Not equivalent to third-party certification |
Applicable Projects
Best fit for display interconnect, medical device, micro-coax, IDC, FFC/FPC, and LVDS harness projects that need a pre-shipment electrical pass for release, with focus on:
High pin-count sequence and connectivity testing for display projects (eDP / LVDS)
Medical projects (patient monitoring / diagnostic) tested to ISO 13485 and IPC Class 3 needs
End continuity and shield integrity testing for micro-coax projects
Multi-pin sequence and short/open full inspection for IDC ribbon projects
Related Applications
100% electrical testing applies to many harness project types, and is especially suited to display cables, medical harnesses, micro-coax, IDC ribbon, and FFC/FPC mixed structures that need a batch release record. Common related capabilities include IPC/WHMA-A-620 assembly inspection, ISO 9001 NCR closure, ISO 13485 medical traceability, and project document control.
Why EDPcable
Outgoing electrical testing is built into the release flow for display interconnect, medical device, FFC/FPC, IDC, LVDS, and micro-coax cable projects
Test plans, fixture needs, acceptance criteria, and record format are reviewed before production
Nonconforming assemblies are isolated and followed through NCR and retest records
EDPcable does not promise tests outside current equipment capability without engineering review
FAQ
- Does "100%" mean every parameter is fully inspected?
- No. It means every assembly in the batch is electrically tested. The exact test items are defined in the agreed test plan.
- Can you use customer-owned test fixtures?
- Yes. Customer fixtures are reviewed for station fit, fixture life, calibration needs, and record output before use.
- Can you provide hipot or insulation testing?
- Only when the current equipment and process scope support it. High-voltage or medical-related test requirements must be defined during RFQ.
- Can we get single-piece test records?
- Yes, if agreed upfront. Because single-piece data volume can be high, the export method and retention rule should be defined during project setup.
RFQ Inputs
For a new project inquiry, please share:
Test item list (standard vs customer-defined)
Acceptance criteria (pass / fail thresholds)
Test fixture plan (customer-provided vs EDPcable-designed)
Test record format (standard vs customer ERP / CSV)
NCR handling time requirements
Whether single-piece detailed records need to be shared
Send the test plan, acceptance criteria, and record format before production release
A clear test plan lets fixture setup, batch records, NCR handling, and shipment release follow the same electrical acceptance basis.
