Product Overview
Double-sided copper clad laminate sheet measuring 12 inches by 12 inches square with a 0.010-inch core dielectric thickness. Both faces carry half-ounce electrodeposited copper foil under the HH/HH specification. Corner stamping includes a directional grain arrow indicating the foil orientation. The thin profile allows clean cutting or shearing with standard sheet metal shears, making this sheet practical for compact RF shielding, planar antennas, ground planes, and custom double-sided printed circuit board layouts.

- Serving as continuous ground planes in custom audio and synthesizer chassis
Frequently Asked Questions
What is the copper foil weight on each face of the sheet?
Both faces carry 1/2 oz per square foot copper foil, corresponding to an 18-micron nominal foil layer.
Can this sheet be cut with ordinary workshop tools?
Yes. At 0.010 inches thick, this thin substrate can be sheared with heavy-duty sheet metal snips, scored and snapped against a straightedge, or cut with a standard shop guillotine shear.
How does this 10-mil sheet differ from standard rigid PCB blanks?
Standard rigid circuit board blanks typically measure 0.062 inches thick, whereas this 0.010-inch laminate provides a low-profile dielectric that flexes slightly and cuts without heavy machinery. The price-break table on this page gives the price per piece at each quantity.
Ten mils of dielectric and two clean faces of half-ounce copper give you the foundation for high-frequency builds without the bulk of rigid plate. Trace your layout, etch your lines, and let the circuit do what it was drawn to do.
