2 layer PCB
Useful for simple circuits, prototypes, sensors, LED boards and basic control electronics.
Layer Count Guide
How to choose PCB layer count for manufacturing.
Layer count affects routing density, signal performance, stackup planning, board thickness and manufacturing complexity.
4 layer PCB
Adds internal plane options for better routing, power distribution and signal reference planning.
Multilayer PCB
Used for dense routing, high speed interfaces, compact electronics and complex power structures.
| Selection factor | Why it matters | Related page |
|---|---|---|
| Routing density | Dense designs may require more layers. | Multilayer PCB |
| Signal integrity | Reference planes help high speed routing. | Stackup Guide |
| Power distribution | Internal planes can improve current paths. | 4 Layer PCB |
| Manufacturing review | Stackup, drill and material requirements must align. | Capabilities |
Review your PCB layer count with engineering.
Send stackup notes and application requirements before production release.
