Automated Circuits & Systems (AC&S) offers a full range of PCB design services. We have established standards for acceptance and delivery which result in a rapid PCB layout cycle. AC&S is very flexible, easy to work with, and will readily work within your PCB design requirements and parameters. We have over 20 years of experience in electronic design, PCB layout, PCB prototype assembly and manufacturing. Our qualified electrical and mechanical engineers have the tools to efficiently manage your engineering work overflow.
Design Range

- High-Density Interconnect (HDI)—buried via, micro via, via-in-pad, fine-line.
- Fine line and BGA Designs.
- FPGA / CPLD / DSP / Microcontroller based Designs.
- Analog, Digital or Mixed designs.

Quality Aspects
- Signal Integrity/EMC/EMI – Our thorough understanding of high speed signaling techniques ensures signal integrity requirements are met.
- Thermal / Reliability Analysis – Analyze all major heat-transfer mechanisms, including convection, conduction, and radiation.
- Signal timing sensitive layouts – Many designs require timing (length) control of high speed signals. We control absolute and relative lengths of nets, including internal die delays if necessary.
- Impedance control – Impedance control, either single ended or differential, is required for most high speed signals. With the good design practice and knowledge of impedance control, we keep designs within their requirements.
- Cross-talk reduction with parallel design
- Design for manufacturing is followed with In-house Quality checking
- PCBs designed to MIL/IPC/UL specifications
- New Parts created are checked and documented.
- Modification done during the design process is recorded.
- Checking of input data, libraries, mechanical dimensions, placement, routing, Gerber data etc.
- Customer feedback and design modifications are documented.
We assure quality, on-time. Our designers work closely with your engineers & our staff is experienced and dedicated to meet customer’s requirements.We understand that success of any project depends on our exact understanding of the customer’s requirements for their project.
Typical requirements for PCB Layout Design
- Soft copy of Intelligent Schematic Diagram, if available. If not available, hardcopy/hand drawn Schematic or net list & Bill of Material.
- Specification/Datasheets for odd & critical components.
- Board outline & dimensions, if particular/specific.
- Special placement instructions, if any.
- Component placement: top side, bottom side or both?
- Keep out zones, if any.
- Special routing instructions, if any.
- Number of Layers desires, if decided.
- Turnaround time required.
Depending on the PCB’s design, there might be some additional requirements also.
