Specifications of Laminates FR-4
When ordering a copper clad laminate board, the FR-4 thickness and the copper foil thickness
must be specified separately.
FR-4 thickness is specified in thou or inches, and common thicknesses range from 10 thou (0.0
10 in, 254 µm) to 3 inches (76 mm).
Copper foil thickness is specified in units of ounces per square foot (oz/ft2), commonly referred
to simply as ounce. Common thicknesses are 1 oz/ft2 (300 g/m2), 2 oz/ft2 (600 g/m2), and 3 oz
/ft2 (900 g/m2). These work out to thicknesses of 34.1 µm (1.34 thou), 68.2 µm (2.68 thou), and
102.3 µm (4.02 thou), respectively. Some PCB manufacturers refer to 1 oz/ft2 copper foil as
having a thickness of 35 µm (may also be referred to as 35 μ, 35 micron, or 35 mic).
1/0 - denotes 1 oz/ft2 copper one side, with no copper on the other side.
1/1 - denotes 1 oz/ft2 copper on both sides.
H/0 or H/H - denotes 0.5 oz/ft2 copper on one or both sides, respectively.
2/0 or 2/2 - denotes 2 oz/ft2 copper on one or both sides, respectively.
Due to the development needs of electronic product installation technology and PCB technology,
the high Tg (Glass temperature) FR-4 products was born.
