Specification design factors
Drawing-defined specification
Geometry and performance
- Gauge, usable width and surface condition define the thin conductor layer.
- Edge quality and winding tension affect tracking and handling.
- Core size and roll build govern unwinding on the downstream equipment.
Selection and processing
Specify the narrow slit width, total gauge, copper layers and allowed burr for the formed part. A grounding-wire construction is not a specification for rolled foil. For shielding, include frequency, continuity and the connection to the enclosure.
Material and form references
Rolled strip, foil and flat wire are defined by material, temper, section and finished-part requirements. Their geometry and test methods differ from those of round wire.
Standards and product formsProduct questions
What affects foil handling and surface performance?
Gauge, usable width and edge quality influence tracking and damage during unwinding. Surface texture and cleanliness affect the downstream bond or contact. Core size, roll build and tension connect the foil to the processing equipment.
Are single-wire strength and complete-strand breaking load the same specification?
No. Single-wire material properties and finished-conductor breaking load describe different specimens. Wire diameter, count, lay and connections define the assembled strand and its test record.
Which dimensions describe foil supplied on a roll?
Specify foil gauge and usable width together with edge condition. The roll record separately identifies core size, roll outside diameter, winding direction and any joints; these are different from foil thickness.
