aluminium heatsinks, machined base plates and thermal-interface confirmation samples from Zhuhai to Spain by air freight: fin crush protection, datum-surface separation and machining-revision traceability

Define the actual aluminium heatsinks, machined base plates and thermal-interface confirmation samples

Identify drawing number, machining revision, alloy, finish, fin pitch, base condition and sample purpose. First articles, revised pieces and destructively tested references need separate status; any thermal pad, release liner or protective oil is listed as a distinct component.

Packing for fin crush protection, datum-surface separation and machining-revision traceability

Carry the load through the solid base in a formed fixture so that fins never support another part. Cover machined datum faces with clean non-marking material, and keep thermal-interface samples flat and away from metal edges that could cut their liners.

Handover checklist in Zhuhai

Put drawing and revision on the inner bag, position map and packing list. Side-light photographs should capture fin alignment and finish before sealing, while heavy bases and light interface sheets remain in separately supported zones.

• Exact item name, material, use and model
• Project, revision, specification, lot and quantity
• Evidence of fin crush protection, datum-surface separation and machining-revision traceability
• Inner-position, carton and photograph mapping
• Truthful transport-property declaration
• Final gross weight and outer dimensions
• Zhuhai handover point and ready time
• Spain postcode, department, appointment and unloading conditions

Confirm air freight with final package data

Heatsink evidence should separate extrusion condition, machining revision and anodising lot. A datum-face protector is fixed to the solid base without adhesive on the measurement zone, while fin-clearance blocks prevent the carton from touching the array. Record whether interface pads are loose references or bonded samples, and photograph every release liner intact. The Spanish team should examine the sample at the tray before lifting it, because grabbing the fin field can create damage after receipt that resembles transit crushing.

Receipt and evidence in Spain

The Spanish engineering team should inspect tray movement, fin straightness and datum protection before removing interface liners. Bent fins, scratches or residue leakage need photographs in the original position and do not by themselves determine thermal-test acceptance.
