4L, 6L and 8L stack-ups
PCB Stack-Up, Explained From the Cross-Section
A stack-up is the sandwich your board is pressed from: copper layers separated by prepreg and core. It decides thickness, impedance behaviour and whether your board can be built at all.
Useful details before decorative ones.

Cross-sections for each layer count
2 layers
One core, copper on both sides. The prototype workhorse: cheap to iterate and fast to build.
4 layers
Routing room plus dedicated power and ground planes. The most common step up when two layers stop working.
6 to 8 layers
More signal layers for dense designs. Tell us the target finished thickness in your first message.
When you request a quote, give us the layer count and finished thickness. If your files imply a stack-up we cannot press, the review flags it before money moves.
Multilayer fabrication
Multilayer PCB fabrication from 4 to 8 layers: FR-4 stack-ups, 0.075 mm trace and space, ENIG, HASL and OSP finishes, prototype lead times from 5 to 7 working days.
