PCB prototypes, empty stencils and process-confirmation boards from Shenzhen to Belgium by air freight: board-revision control, ESD separation and stencil-frame protection

Define the actual PCB prototypes, empty stencils and process-confirmation boards

PCB lots should distinguish project number, board ID, revision, layer count, surface finish and intended use. Reworked boards, obsolete references and build-ready prototypes belong in separate bags, while an empty framed stencil needs its own mesh-condition and opening-area record.

Packing for board-revision control, ESD separation and stencil-frame protection

Place each board revision in a suitable ESD bag or rigid carrier without loading connector edges or tall components. Support the stencil by its frame so that neither the mesh nor the squeegee-contact surface touches hard packing, and align process cards with the same revision index.

Handover checklist in Shenzhen

A Shenzhen handover sample should be traceable from the build list to the board label, ESD package, stencil frame and photograph. If inspection opens a seal or replaces a board, issue a fresh packing version instead of annotating an old sheet informally.

• Exact item name, material, use and model
• Project, revision, specification, lot and quantity
• Evidence of board-revision control, ESD separation and stencil-frame protection
• Inner-position, carton and photograph mapping
• Truthful transport-property declaration
• Final gross weight and outer dimensions
• Shenzhen handover point and ready time
• Belgium postcode, department, appointment and unloading conditions

Confirm air freight with final package data

A practical PCB consignment also needs a board-to-stencil matrix: each stencil frame is tied to the matching board revision, paste-side orientation and process-card version. Keep obsolete comparison boards visibly quarantined, photograph stencil mesh before the lid closes, and never place loose tooling on populated prototypes. The Belgian recipient should know which package may be opened in an ESD-controlled area and which framed stencil requires two-person handling.

Receipt and evidence in Belgium

The Belgian development team should check the stencil frame, PCB corners and ESD seals before boards enter a trial build. Freight delivery does not approve electrical behaviour or printing performance; mixed revisions, crushing or seal changes must be photographed before use.
