Schematic Design
Circuit schematic development and engineering review based on functional requirements, component selection, interfaces and system architecture.
PCB DESIGN ENGINEERING
PCB Design Engineering Services
Excel Circuit provides PCB design engineering for high-speed, HDI, RF, FPGA, power electronics and mixed-signal products. Our engineers coordinate schematic requirements, component placement, routing, stackup, signal and power integrity, and DFM/DFA so the released design can move into fabrication and assembly with fewer production handoffs.

Manufacturing & Assembly Support
Support PCB fabrication, component sourcing, in-house SMT assembly and production feedback when required.
Engineering Detail
Key PCB Design Considerations
PCB layout is an engineering discipline. Placement, routing and stack-up decisions must account for electrical behavior, mechanical constraints and the realities of fabrication and assembly.
