Printed circuit board optimization services, capabilities, and testing
PCB layout
Our PCB layout services include stack-up design, constraint setting, component placement, routing and Gerber generation handled by a team with 20 years of experience. We specialize in DDR, fine pitch BGA, component placement optimization, constraint settings and much more.
Schematic capture
We can create schematics from specifications, marked-up schematic sheets, or block diagrams and verbal discussions. We accept schematics in any format (PDF, sketch, etc.) and can convert that into preferred CAD format. As part of our process we validate the BOM.
Reverse engineering
Are you missing your original PCB design data and documentation? We can take an existing board from a bare board, an assembled board, existing drawings, and we can create a new design with all supporting documentation.
Cost optimization
We can review an existing product or design and propose methods for cost reduction. In many cases, layer reduction can be achieved by using smaller geometries for conductors and vias and the use of laser-drilled microvias.
PCB stack-up design
Before we start the layout design, we will do an in-house stackup design so that all the design objectives are met. We will also suggest if HDI technology is required or could help in PCB optimization.
Signal integrity services
We can perform signal integrity services on any high-speed board designs that we make. We will take care of control impedance and crosstalk requirements; we will take care of PCB materials that are suitable to achieve a given set of signal integrity specifications.
