To get in control of your electronics design, continuous analysis throughout the design cycle and close cooperation between schematic design, PCB design, and analysis engineers is key.
Analysis results give detailed insights in how your electronics are going to behave. The better the models in the design tools reflect the real-life behavior of the components, the more reliable the analysis. This is why our engineers sometimes harass component suppliers to get more accurate measurements on a certain new component, while at the same time they are confident they can trust their tooling to be accurate for established components. Our engineers work with component models and design tools day in, day out, so the models come to life. They have a feel for when a model is good enough, how analysis results translate to real life, and what they need to do to get a better layout in the next iteration.
For every design that we make, certify, or troubleshoot, we advocate the use of our design and analysis expertise.
Our design engineers make it their priority to understand end-customers applications and the resulting requirements to the fullest. Not only on the hardware level, but also for the interfacing software and mechanical requirements. During specification, design, realization and testing phases, we keep in close touch with software and mechanical engineers to immediately iterate towards a desired product that is easy to manufacture and assemble. Of course we make use of our expertise below to create an excellent design.
We are used to closely collaborate with more than one partner on complex high speed designs, where each partner brings their own expertise to the table.
PCB design is the last chance to make or break a product. Success and PCB quality doesn’t just depend on knowing how to work the layout-tool. A clear understanding of how to interact with tooling for front end data entry, component library and analysis, in combination with knowing how to use tooling results to improve the design makes all the difference.
Our team has extensive design experience in high speed, multi-layer and high performance boards together with encyclopedic domain knowledge of security, telecommunication, networking and consumer systems. We work with proven design methodologies with strict internal guidelines and review processes. At the same time, we have an extreme commitment to your deadlines and have the reputation for being flexible so you can deliver on time.
Signal integrity analysis
In high-end designs, high speed behavior often affects more than 80% of the signals on the board. Transmission line behavior is complex, and simulating it is essential to get an understanding of signal behavior. Manufacturing tolerances of various components must be considered in the simulations, for the combinations specific for the design. Investigating signal integrity in any step in the design process gives insight in how everything on board influences the outcome. This way you can take out signal integrity issues before the PCB goes in production.
Power integrity analysis
The success (and failure) of electronic designs depends on whether the desired voltages and currents are met from source to destination on the circuit board and in the entire system. For high speed boards, the influence of switching signals on power rails becomes larger and this leads to more electromagnetic interference. In addition, the voltage ripple at chip pads needs to be kept within boundaries as well as the SSO (simultaneous switching output), power and ground bounce. Power aware simulation and power integrity analysis is key to prevent PCB respins.
Modern-day multifunctional devices support aggressive, multiple timing variations in their designs. All timings must be perfectly aligned to get the design up and running fast, without any intermittent failures in the resulting PCBs. For high speed DDR memories, perfect timing and compensation for any latency between clock lines and address lines is key to guarantee fast, stable and reliable memory operation at the maximum speed supported. Differences in trace lengths, the use of vias and cross talk all influence timing for high speed designs. To design out any timing disturbances and avoid intermittent failures in the product, timing analysis and verification early in the design phase is key.
DfM/DfA Design for Manufacturing / Design for Assembly
At each successive step of the New Product Introduction (NPI) process, the cost of rectifying a product design problem increases enormously. Sintecs uses the Mentor Graphics Valor NPI platform to provide comprehensive Design For Manufacturing (DFM) and Design For Assembly (DFA) analysis that can be applied concurrently with the design flow for maximum advantage, or at entry to manufacturing.
Component libraries eliminate the time-consuming process of manually entering parts with symbols, footprints and their pin mapping. PCB footprints with optimal geometry for most PCB processes are critical to the design of excellent PCB layouts and the products that are built with it.
Using high quality, well-maintained libraries reduces respin risk. For components lacking in your library, we supply parts with schematic symbols and PCB footprints according to the IPC-7351A standards. We have a library with thousands of components available for immediate use, and we create new ones when needed, on time and according to a Service Level Agreement (SLA).
