Multilayer circuit boards can better allocate energy, reduce cross interference, while eliminating electromagnetic interference and supporting high-speed signal transmission.

Great PCB Provide PCB service stack up with a range of 4 to 32 layers, plate thickness from 0.4 mm to 3.2 mm, 18 μ m to 210 μ m (0.5 ounces to 6 ounces), inner copper thickness from 18 μ m to 70 μ m (0.5 ounces to 2 ounces), minimum spacing to 3 mil.

The following figure shows the standard PCB service stack up commonly used by Great PCB. The actual stacking will depend on the PCB material and many other elements. If you have special requirements for PCB stacking, please email your board thickness and layers. We will share the corresponding stacks accordingly.

Standard Four PCB Layer Stack Up

Pre‐Preg Thickness ‐ 1080 =  3.04 mil ‐ 2116 = 4.67 mil ‐ 7628 = 7.68 mil

Standard six PCB Layer Stack Up

Pre‐Preg Thickness ‐ 1080 =  3.04 mil ‐ 2116 = 4.67 mil ‐ 7628 = 7.68 mil

 Several commonly used stack up in FPC

single sided board

Made of single-side copper clad plate material, and then covered with a protective film , forming a soft circuit board with only a single layer of conductor.

Double-sided flexible board

Using double panel copper plate material, both sides plus a layer of protective film, become a circuit board with double layer conductor.

 multilayer flexible board

Taking the single-sided copper plate material and adhesive as the basic material, using the process similar to generating the double panel with the substrate, and the material is synthesized into the circuit board with multi-layer conductor structure through multiple pressure.
