PCB Design & Layout
Schematic review, component placement, routing, stack-up planning, high-speed constraints, and production file preparation.
Excel Circuit is an electronics engineering and manufacturing service provider specializing in PCB design, hardware development, PCB fabrication, component sourcing, SMT assembly and prototype production.
Our engineering team supports complex PCB projects including high-speed digital, HDI, RF, embedded and FPGA, power electronics and mixed-signal designs.
PCB fabrication is coordinated through qualified manufacturing resources selected according to project requirements, while SMT assembly is supported by our own production capability. This allows us to provide customers with one coordinated service from engineering through prototype and production.
Each service can be used independently or combined into a turnkey workflow according to the project stage.
Schematic review, component placement, routing, stack-up planning, high-speed constraints, and production file preparation.
Controlled impedance, return paths, differential routing, PDN considerations, and layout risk review for complex boards.
Material, stack-up, copper, via, surface finish, tolerance, panelization, and fabrication process coordination.
SMT, through-hole, fine-pitch and mixed-technology assembly with production documentation and inspection planning.
BOM review, sourcing coordination, approved alternatives, lifecycle risks, and traceable purchasing documentation.
Electrical and functional test coordination, programming, cable integration, enclosure assembly, and final release needs.
Clear inputs and early engineering questions help reduce avoidable quotation changes, production holds, and repeat-build risk.
Provide files, quantities, schedule, application, and acceptance criteria.
We identify technical questions, missing data, and manufacturability concerns.
Materials, processes, test needs, deliverables, and assumptions are clarified.
Production follows the approved data with planned inspection and testing.
Feedback and build records support delivery and future repeat orders.

Inspection and testing should match the board technology, application risk, customer specification, and production volume. We review these requirements during quotation so the build plan is clear before release.
Project decisions are adapted to the electrical, mechanical, environmental, regulatory, and production needs of the application.
Control, sensing, motor drive, communication, and long-service-life electronics.
Control modules, power systems, connectivity, and production-oriented hardware.
Controlled-impedance, high-frequency, antenna, and signal-integrity requirements.
Mixed-signal, measurement, compact integration, and verification-focused designs.
Current handling, thermal control, isolation, protection, and power conversion.
Compact wireless, sensing, battery management, and connected hardware.
Complex interconnect, high-reliability design review, and documentation needs.
Application-specific boards, subsystem integration, and tailored production flows.
Use our capability information, case studies, and Knowledge Center to prepare design data and evaluate production options.
Review manufacturing, assembly, material, technology, and production scope.
See engineering considerations across industrial, automotive, communications, data acquisition, and power projects.
Explore practical guides covering PCB design, layout, manufacturing, materials, signal integrity, and assembly.
Send your Gerber files, BOM, drawings, source design data, or project requirements. We will review the scope and identify the information needed for a clear quotation.
