The components of multilayer PCB: copper foil
A multilayer board consists of copper foils, thin rigid laminates and prepreg sheets.
The standard thicknesses for copper foils are shown below| µm | 5 | 9 | 12 | 17.5 | 35 | 70 |
| oz | 0.14 | 0.25 | 0.34 | 0.5 | 1 | 2 |
Thick copper (heavy copper) foils are used for voltage and ground planes by some electronics
companies. Thicknesses up to 210 µm (6 oz) are specified for high voltage coil boards. For very
fine-line boards, 5 and 9 µm (0.14 and 0.25 oz.), ultrathin copper foils are also used for the outer
layers.
Copper foils are used as copper cladding of the thin laminates used in the inner layers. Such
laminates can be delivered with different copper thicknesses on the two sides, for example,
17.5 µm (0.5 oz.) on one side for a signal layer and 35 µm (1 oz.) on the other side for ground
or voltage planes.
Copper foils are sometimes used directly as cap foils for the outer layers. In such cases, the
copper foils are bonded to the next layers by means of prepreg and form the outer layer circuits.
For signal outer layers, the copper foil thickness is usually 17.5 µm (0.5 oz.) or 35 µm (1 oz.)
depending on the minimum track width and spacing. In the case of high-density fine-line boards,
5 or 9 µm (0.14 or 0.25 oz.) ultrathin copper foils can be the only solution to achieve the required
high resolution when etching the board.
For signal inner layers, a 35 µm (1 oz.) copper foil is normally chosen. For ground and voltage
planes, 35 µm (1 oz.) and 70 µm (2 oz.) copper foils can be used. However, the thicker foil, the
more difficult it is to fill the apertures in the planes around the hole wall with epoxy flowing from
the prepreg sheets during lamination.
