Why “inspected” is not a measurement
A stamped “QC passed” tells you somebody looked at the batch. It does not tell you what they measured, against which revision, or what value would have caused a reject. If a shipment later fails to seat in a heater, that stamp gives your incoming-goods team nothing to compare against.
Our batch report is built so it can be checked from the other side of the world: every field names a drawing, a nominal value, a tolerance and a measured result. It ships with the goods and, for own-brand orders, is issued under the customer's part number.
The six fields
| Field | Definition | Reference |
|---|---|---|
| Geometry ID + revision | Which drawing the batch was ground to | Drawing number, revision letter |
| A / B / C / D measured | Length, shank, face width and reach measured on the batch | Nominal ± tolerance on the drawing |
| Shank tolerance | Seating and thermal contact in the heater | ±0.05 mm |
| Plating build-up | Nickel barrier and iron layer thickness for that batch | Bath record, measured thickness |
| Batch number + date | Traceability back to the plating and grinding run | Packing label |
| Wetting test result | Solder-test outcome before release | Internal test method |
The two we will not sign without
Measured shank. It is the one dimension that decides whether the part fits at all, and it is the one most often missing from a supplier's report because it requires measuring the seating surface rather than the visible tip.
Wetting result. A tip can be dimensionally perfect and still fail to solder if the plating is damaged or contaminated. A solder test before release is the only cheap way to catch that.
Everything else on the report adds traceability, but these two are the release criteria. We do not substitute a visual inspection for either.
Using the report at incoming goods
- Match the geometry ID and revision to the drawing attached to your purchase order.
- Sample-check B (shank) against the stated ±0.05 mm with a calibrated micrometer, not a vernier.
- File the batch number with the goods so a later question can be traced to one plating run.
- Keep the wetting result with the batch record; it is the reference point if a later shipment behaves differently.
For EU shipments the same pack carries the RoHS 3 (EU) 2015/863 and REACH SVHC declarations for that batch. Bare soldering tips are passive consumables and are not CE marked — if a supplier offers a CE certificate for one, ask which directive they believe applies. Our quality and compliance page states exactly what we declare and what we do not.
