Multilayer PCBs

Multilayer PCBs Icon

Multilayer PCBs are the biggest volume technology sector of PCB’s. They have a higher number of interconnections enabling more complex designs.

A PCB with more than two copper layers is considered a Multilayer PCB. The extra layers are internal within the PCB and allow a higher density of connections. Increased layer count enables more complex designs and can help reduce final product size.

The most common multilayer PCBs fall within the range of 4 to 16 layers. As technology advances and electronic devices become more sophisticated, we have seen an increasing demand for higher-layer count multilayer PCBs. Delta Impact can now offer 56 layers to meet the requirements of these advanced applications.

If you’re seeking a Multilayer PCB, whether it’s a 4-layer board for a compact application or a high-performance 16-layer PCB for cutting-edge technology, we have the expertise to meet your requirements. Contact us today to discuss your project specifications.
