Multilayer PCBs are an important part of our portfolio. In order to take this very complex product into account, we give top priority to high-end quality and a long-term supplier relationship.

The various companies are carefully selected and are subject to a very strict continuous
auditing process.

What is a Multilayer PCB?

It is a PCB with at least 3 copper layers (mostly an even number, starting from 4 layer). The inner layers are processed as pairs. They are bonded together with prepregs as an isolationlayer. The top and bottom layers are copper and are used to place the components on one or both sides.

The connection between layers is made by drilling holes through all layers, but can also added by buried or blind drilled holes, depending on the complexity of the layout.

Multilayer are used for computers, phones, medical equipment, car systems, aeroplane devices etc

Please contact CS if you need further information or assistance, our engineers are
happy to help you.
