Multilayer PCBs
Manufactured to Your Specifications and Delivered On Time
Multi‐layered printed circuit boards are a very common choice for applications involving complex, dense circuitry designed into a small space. They consist of 3-20 conductive layers and a single solder mask insulating layer on the top and bottom. Standard overall thicknesses range from .031” ‐ .125”. The use of multiple layers significantly reduces the size of the circuit, which is beneficial in manufacturing assemblies for compact products.
The ability to provide EMI shielding layers makes these circuits useful for complex, highly sensitive electronic applications such as motherboards and radio frequency (RF) boards. All component types can be attached to multilayer PCBs, and current-carrying capabilities of signal traces ranges from a few milliamps to several amps.

Designing for Impedance Control in Multilayer PCBs
Tramonto Circuits has decades of experience manufacturing multi-layer printed circuits for OEMs and Tier 1 Suppliers in the medical, transportation, aerospace, computer, and telecommunications markets.
Precision and quality in design and manufacturing are a priority to ensure reliable signal transmission in your completed assembly. After receiving your design submission, our engineers conduct a Design for Manufacturing Assessment. Maintaining signal integrity in multilayer PCBs is achieved by reviewing the layer stackups in your design. If our engineers identify potential issues related to the sequence or trace thickness, width, or distance, they will provide recommendations to prevent signal degradation. Factors in addition to impedance control will be reviewed based on your design specifications.
We are ISO 9001:2015 certified and perform quality checks at every phase of production. With a 99% quality ratio since 2008, you can trust that your multi-layer printed circuits will be delivered on time and to your specifications.
