Consigned Component Guidelines
Send a kit that can be identified, counted and released for assembly without guessing. Agree the material handoff before shipping customer-supplied components.
- Identity
Exact MPN, BOM line and lot information
- Condition
Packaging, handling and exposure records
- Quantity
Build need, agreed allowances and returns
A consigned kit is more than a box of parts.
Consigned components are supplied by the customer for use in an agreed assembly build. Full and partial consignment both need a clear split of sourcing responsibility, a receiving plan and a way to handle shortages or discrepancies.
Contact us before shipping customer-supplied components to confirm packaging, quantity allowances, inspection needs, schedule impact and how unused parts will be handled.
- Full consignment
- The customer supplies the agreed component set for the build.
- Partial consignment
- Customer and assembler each source explicitly assigned BOM lines.
- Receiving release
- Identity, quantity and condition are reviewed before material is made available for the build.
What to resolve before release
Use these review prompts with the actual design, component documentation and agreed manufacturing process.
Map every package to the released BOM
Label parts with the exact manufacturer part number and the relevant project/BOM line. Retain original manufacturer labels when available. A supplier SKU or value alone may not identify the correct package or option.
Agree usable packaging before shipment
Confirm reel, cut-tape, tray or tube requirements and any leader or loading needs. Protect components against physical damage and mix-ups; do not assume loose components are automatically acceptable.
Preserve handling and exposure information
Keep applicable MSL, ESD and temperature information with the material. For moisture-sensitive devices, record package opening and exposure history. Repacking or resealing alone is not evidence that a device meets its handling requirements.
Plan quantities beyond the fitted BOM
Separate fitted build quantity from agreed setup and additional-material allowances. Review high-value, scarce and packaging-constrained parts individually instead of applying one unexplained overage to every line.
Quarantine differences instead of guessing
Identify shortages, damaged packaging, uncertain identities and label mismatches at receiving. Obtain a documented disposition before using suspect material or substituting another part.
Reconcile what remains after the build
Agree how unused reels, opened packs, rejected material and customer-owned parts will be counted, labeled, stored or returned. Keep the final accounting linked to the purchase order and assembly revision.
Packaging questions to resolve before dispatch
These are suggested checks, not a declaration that every packaging type is accepted for every job.
On a small screen, scroll the table horizontally to see every column.
| Supply format | Prepare | Confirm with the assembly team |
|---|---|---|
| Reel | Original identity labels, protected tape and clear usable quantity. | Reel compatibility, leader/trailer needs and treatment of partial reels. |
| Cut tape | Protected pockets, consistent orientation and identified strips. | Minimum usable strip/loading requirements and setup allowances. |
| Tray | Correct tray orientation, secure stacking and visible part/lot identity. | Tray suitability, handling restrictions and any temperature limitations. |
| Tube | Protected ends, clear identity and controlled component orientation. | Tube compatibility and any special feeding or transfer work. |
| Moisture-sensitive material | Applicable labels, exposure history and protective packaging. | Receiving status and any approved conditioning before assembly. |
| Loose or unusual items | Individual identification and damage protection. | Explicit acceptance and any manual handling or inspection work. |
Keep the approved project requirements in control. Record uncertainties, agreed exceptions and the supporting evidence before the affected operation is released.
Separate the build need from the agreed allowance.
The planning calculator below uses a transparent convention: round up the fitted requirement plus a percentage allowance, then add a fixed setup quantity. Its defaults are illustrative—not GlobalWellPCB policy. Confirm the resulting quantity per BOM line, especially for expensive or difficult-to-replace devices.
- Base requirement
- Board quantity × fitted quantity per board, for the chosen variant.
- Additional allowance
- A percentage of the base requirement, rounded up together with that base.
- Fixed setup quantity
- A separately agreed quantity added after rounding; avoid double-counting allowances.
Consigned quantity planner
Illustrative inputs—not a factory allowance policy. Review one BOM line at a time.
The allowance is additional material as a percentage of the fitted requirement, not a yield-loss formula. Confirm both allowances to avoid double-counting. Quantity fields require whole numbers; the percentage supports up to four decimal places.

Any conditioning work is explicitly approved.
Use device and packaging restrictions; no blanket bake recipe.
Fitted quantity and per-line allowances are reconciled.
Separate setup quantities from percentage overage.
Receiving discrepancies have an owner and disposition.
Keep suspect material out of the released kit.
Final unused and rejected quantities will be recorded.
Link the accounting to the project and BOM revision.

Practical answers
before release.
Use these answers to frame the discussion. The approved project requirements remain the authority for the build.
Can I send exactly the fitted BOM quantity?
Confirm this before shipping. Setup, feeding and other agreed material allowances may require more than the number fitted to finished boards. High-value or scarce parts should have a line-specific plan rather than an assumed percentage.
Can I send cut tape instead of reels?
Confirm tape format, loading needs and quantity allowances with us before preparing the component kit for your assembly.
Should all moisture-sensitive parts be baked?
No blanket bake instruction is appropriate. Evaluate the exact device, exposure history, packaging and applicable handling procedure. Temperature and time must not be guessed; some packaging and components have specific restrictions.
Does a sealed bag prove the parts are ready for reflow?
Not by itself. Identity, storage/exposure history and the applicable device requirements still need review. Record any uncertainty and agree how it will be resolved before the material is released.
What happens to unused customer-owned parts?
Agree this in the order: return, storage or another authorized disposition. Include how quantities, opened packaging, lot identity and any rejected material will be recorded. No default storage or return promise is made here.
