Tin-Plated Copper Strip RFQ Checklist
Specify the base copper, temper and finished dimensions first. Then add tin type and thickness, adhesion and solderability requirements, downstream forming or joining, and the coil format.

Separate base copper, plating and downstream processing
| Group | Information to provide |
|---|---|
| Base copper | Grade, temper, width/thickness, tolerances, edge/burr and electrical requirement |
| Tin system | Matte, bright or reflowed finish as required; process/chemistry identification |
| Plating dimensions | Thickness by face, minimum/local criteria, coverage and measurement method |
| Acceptance | Adhesion, solderability, aging and whisker requirements with agreed methods and limits |
| Processing | Stamping/bending sequence, exposed cut edges, joining and finished-part checks |
| Supply | Coil format, quantity, protection, labeling and inspection records |
Record the trial and order basis
Keep the drawing revision, sample identifiers, method, test conditions, acceptance limits and measured results together. Resolve open fields with the specification owner before comparing offers or releasing a changed construction.
