The multilayer PCB

15-03-2021

Printed circuit boards (PCB) are becoming more and more complex: they are getting smaller while at the same time they have to be able to do more. As a result, single and double-layer PCBs are becoming less and less developed, whereas the multilayer PCBs are more often in demand these days. But what makes a multilayer PCB potentially more interesting for your design?

A multilayer PCB is a PCB that consists of more than the two visible layers. The more layers the PCB consists of, the more connectivity it can handle. This allows the PCB to be drawn more compactly by an engineer. These intermediate layers are created by attaching thin layers together by means of metalized holes, so-called vias, which provide an interconnection between each layer. In addition, so-called via constructions are possible, such as blind and stacked vias, to possibly save space.

In theory, the multilayer PCB can contain infinitely many layers. In practice, it often goes up to a maximum of about 30 layers. Up to 16 layers fall under the 'standard' PCB development, above this number you will end up with the specialists. Depending on the wishes of our customers, VEDS Group can develop all specializations for you.
