Raytron at CCD2026: CCA Wire, Strip and Foil

Round and flat wire

Specify diameter or width/thickness, copper fraction basis, core material, condition and electrical/mechanical requirements. Review continuous coverage, cladding symmetry and the effect of drawing, rolling, tinning, insulation or joining on the delivered conductor.

Fully clad and embossed strip

“Fully clad” describes copper coverage around the delivered cross-section. Inspect any edges exposed by subsequent slitting, stamping or forming. For embossed strip, define the pattern and finished thickness together with flatness, camber, burrs and the required contact or lamination function.

Precision foil

Record total and layer thickness, cross-width variation, width, edges, surface cleanliness and roll quality. Evaluate the foil after the actual winding, die-cutting, lamination or joining process rather than relying only on average thickness.

Inputs for the next sample

• Confirm copper-ratio definition, aluminum core, product form, dimensions and temper;
• Calculate density, conductivity, resistivity, mass per unit length and comparison with the current material;
• Confirm welding, crimping, stamping, slitting, tinning, insulation or other downstream processes;
• Define incoming, in-process, finished-product and reliability tests;
• Set sample, pilot, audit, change-control and production-release gates;
• Use approved drawings, technical agreements and batch inspection records as the delivery basis.
