Multilayer PCB FAQ
1.How long is the delivery time for your multilayer PCB?
Depending on the project, our delivery schedule can vary from 24 hours to 2 weeks.
2.How many layers of PCB manufacturing services do you provide?

We can provide the highest precision boards with up to 2 to 64 layers.

3.What are the differences between single-layer and multi-layer PCBs?
A single-layer board has only 1 layer, while a multi-layer PCB has more than two layers.
4.Do you offer multi-layer PCB manufacturing?

Yes, we offer multilayer PCB manufacturing with dense and high count multilayer boards.

5.What is a multilayer PCB?

Multilayer PCB manufacturing or production is the process of manufacturing a PCB with more than two layers combined; the characteristics of a multilayer PCB may require a more complex design than a double-sided PCB!
