Requirements & Architecture
Translate product goals, interfaces and constraints into a practical board architecture.
Excel Circuit provides PCB layout services for high-speed, HDI, RF, fine-pitch BGA, FPGA, power electronics and mixed-signal boards. Our engineers coordinate placement, routing, layer stackup, impedance requirements, return paths, thermal constraints and manufacturability to deliver production-ready PCB data.
Complete engineering support
Excel Circuit supports a single design stage or the complete hardware workflow, coordinating electrical performance, mechanical constraints, component availability and manufacturing requirements.
Translate product goals, interfaces and constraints into a practical board architecture.
Create clear, reviewable schematics with validated components and power structure.
Build controlled symbols, footprints and component data for reliable layout.
Optimize component placement for performance, assembly, mechanics and serviceability.
Plan layer stack, impedance, planes and routing rules around design needs.
Release source files, Gerber or ODB++, BOM, centroid files and drawings.
PCB design case studies
Explore how different electrical, mechanical and manufacturing requirements translate into practical PCB architecture and layout decisions.
01Industrial controlA compact controller architecture combining field interfaces, sensing, processing and protected power domains.
02High-speed digitalA multilayer digital platform with dense BGA fanout, high-speed interfaces and constrained mechanical boundaries.
03RF & wirelessA wireless module integrating RF paths, digital control, low-noise sensing and regulated power.
These examples illustrate representative project types and engineering approaches. Project details are adapted to protect customer confidentiality.
Design workflow
Clear review gates keep technical decisions visible and reduce costly changes after fabrication.
Deliverables
Receive organized source data, production outputs and supporting documentation with a clear revision trail.
Why Excel Circuit
Layout decisions account for fabrication and assembly constraints early, not after files are released.
Design, component sourcing, PCB fabrication and assembly can be coordinated through one team.
Reviews focus on the issues that drive board respins: interfaces, return paths, power integrity, thermal stress and manufacturability.
Typical applications
Share your requirements, existing files and production targets. Our engineering team will review the project and recommend a practical next step.

Practical answers about files, schedule, engineering support, production coordination and confidentiality.
To start PCB Design & Layout Services, send your system requirements, block diagram, schematic or netlist if available, component datasheets, mechanical constraints, connector locations, stackup preferences, and any impedance, power, thermal, EMC or test requirements. Existing Gerber or ODB++ files can also help us understand a previous revision.
Lead time depends on design maturity, complexity, quantity, material or component availability, testing scope, and how quickly engineering questions are resolved. We confirm the schedule after reviewing your files; urgent prototype or quick-turn options can be discussed where the required process and materials permit.
We can review common production outputs such as Gerber and ODB++, as well as native EDA data when agreed during the file review. Because library versions, third-party models and tool releases vary, tell us the software and version used before transfer so we can confirm the working format or recommend a neutral export.
Yes. We can work from an existing design, production package or previous revision. We first check completeness, revision control and the requested scope, then identify any missing data, manufacturability risks or changes that need your approval before work begins.
Yes. SI/PI review or simulation can be included when the design contains high-speed interfaces, sensitive analog sections or demanding power rails. Scope depends on available stackup data, IBIS/SPICE models and measurable acceptance targets, so it is quoted separately when needed.
Yes. Excel Circuit can coordinate engineering review, PCB fabrication, component sourcing, assembly, inspection and testing under one project. You may also order only the engineering stage and release the approved production package to another manufacturer.
Project files are limited to personnel and qualified partners who need them for quotation and delivery. Excel Circuit uses reasonable technical and organizational safeguards, does not publish customer designs without permission, and can work under a mutually agreed NDA. Your signed NDA or project agreement controls where it provides specific protections.
Final scope, price and lead time are confirmed after engineering review of your current files and requirements.
