Exact-spec manufacturing from customer drawings
Build-to-Print Cable Assembly Manufacturing
For programs where the customer drawing, BOM, and process notes are the manufacturing authority.
Build-to-print means EDPcable manufactures strictly to the customer-approved drawing, BOM, and process requirements. If manufacturability, material availability, or process differences create a change suggestion, EDPcable notifies the customer in writing and waits for approval before implementation. This model fits released designs, registered products, multi-factory programs, and transfer projects where uncontrolled optimization would create risk.
Capability scope
Best fit when the customer drawing is mature and should not be changed freely. Incomplete drawings should run through engineering review or DFM first.
Manufacturing follows the customer drawing, BOM, process notes, tolerances, labels, and inspection requirements
Drawing authority and change-control rules are agreed before production
BOM substitutions are blocked by default unless the customer-approved substitution process allows them
EDPcable is responsible for execution; the customer keeps design authority and design responsibility
Process Flow
| Step | Station / Action | Control Point | Output Record |
|---|---|---|---|
| Drawing intake | Customer provides the complete drawing / BOM / process requirements | Completeness confirmed | Drawing intake record |
| Drawing completeness review | Key dimensions / BOM complete / process executable | Notify customer to complete if incomplete | Review memo |
| Lock manufacturing authority | Drawing, BOM, process notes, and revision enter controlled state | Production basis matches customer-approved files | Controlled execution record |
| Material procurement | Purchase specified materials per BOM | No substitution; substitution needs customer approval | Procurement record |
| Sample execution | Build the sample to drawing | Deviation identification + customer notice | Sample record |
| Production execution | Strict build to drawing | Stop line and notify customer if an issue is found | Production record |
| Change control | Change suggestion → written notice → customer approval → implementation | Closed loop + controlled revision update | Change review record |
Inspection Checkpoints
| Checkpoint | What is checked | Record | Limit |
|---|---|---|---|
| Drawing completeness | Key-dimension tolerances / BOM complete / process executable | Review memo | Submit to customer to confirm or complete when information is incomplete |
| Incoming material match | Material matches the BOM | Incoming inspection | Substitute material needs customer approval |
| In-process check | Key dimensions / process match the drawing | In-process inspection | Sampling ratio per drawing requirement |
| Pre-shipment inspection | Whole batch matches drawing / labels / documents | Outgoing inspection | Documents per customer requirement |
Deliverable Records
| Deliverable Record | Stage | Use | Limit |
|---|---|---|---|
| Drawing intake record | Project start | Received drawing revision / completeness confirmation | A new customer revision needs re-intake |
| Review memo (if any) | Project start | Notice of incomplete-drawing issues | Does not replace customer drawing correction |
| Controlled execution record | Project start | Production basis locked to customer-approved files | Shared as agreed per project |
| Change review record | On change | Change suggestion / customer approval / implementation record | Not implemented before customer approval |
| Procurement record | Production | Evidence of BOM material purchasing | Substitute materials flagged |
| COC | Production | Strict build-to-drawing batch release | Not equivalent to third-party certification |
Applicable Projects
Best fit for cable and harness projects where the drawing, BOM, process notes, and revision boundary are already defined, with focus on: Review before commitment:
Projects already in a medical / industrial registration flow (design changes must stay strictly controlled)
Multi-factory compatible production (must run to one drawing and revision)
Projects validated at another factory or legacy projects transferred to EDPcable
Projects where the customer has completed design definition and EDPcable manufactures to the controlled files
Customer drawing incomplete → run engineering review and drawing control first
Customer has only a physical sample, no drawing → run a reverse engineering assessment first
Customer wants the factory to suggest optimizations → run the free DFM review first
Related Applications
Build-to-print can be applied to display interconnect, medical device, FFC/FPC, IDC, LVDS, and micro-coax harness projects. Customers can use the free DFM review to confirm drawing maturity, engineering review and drawing control to confirm revision boundaries, or reverse engineering when only a physical sample exists; change control and batch release records are usually used together with the ISO 9001 quality system.
Why EDPcable
Clear separation between customer design authority and EDPcable manufacturing execution
Written approval is required before material substitution or process change
Supports released or transfer programs across display interconnect, medical device, FFC/FPC, IDC, LVDS, and micro-coax cable work
ISO 9001-style document and change-control records support the execution path
FAQ
- Does build-to-print mean no engineering review at all?
- No. EDPcable still checks drawing completeness and manufacturability. Problems are reported to the customer instead of being changed unilaterally.
- What happens if the drawing is clearly wrong?
- EDPcable stops the affected work, notifies the customer in writing, and waits for direction before proceeding.
- Can EDPcable substitute a BOM item when material is unavailable?
- Not by default. Substitution requires the customer's written approval and the agreed substitution review process.
- Can a DFM stage come before build-to-print?
- Yes. A project can start with DFM review, then switch to build-to-print once the customer-approved drawing package is mature.
