EDALITY has released many PCB layouts intended for usage in different industries. We cooperated with different companies and engineers who were sharing with us various approaches to the development process and applied requirements traditional for alternative engineering schools.
Having this rich experience of partnering with best specialists in electronics we developed a complex of measures providing the best quality of a PCB design at the end of every project engineering cycle. It contains a few important stages described below.
1. Checking Component Library Quality
First thing first, taking care of the quality of the component library is highly important. Wrong clearance between pins or absent thermal pad may cause multi-million damage but can be easily prevented by choosing the right source of library components or running special library check procedures. Downloading free databases available on the Internet is not acceptable when complex and expensive electronic devices are under development.
2. Following Requirements
The engineering team of EDALITY practice proven approaches in PCB design confirmed by professional committees and described in field-specific literature. We support requirements of IPC standard and ready to consider individual technical requirements of every single design when it is needed, but only within the limits of used technological stackup.
3. Running Electrical Simulations
Running Signal Integrity analysis and Power Integrity analysis allows to double-check if all the high-speed lines were freed of parasitic effects and power planes will not overheat. Electrical analyses provide a layout designer with a look from the new sides half-hidden before. Oftentimes, results of SI and PI analyses allows not only to avoid problems possible but also to improve top-limit characteristics and an overall margin of safety of a PCB design.
A fresh look of a professional eye always helps to verify the general harmony of the design on every stage of its life from placement till completion. But it also helps to find unexpected unforced errors typical for every human being. Cross-checking by different engineers is in extensive use within EDALITY.
5. DFM check
Last, but not least stage of quality control if DFM check. It is a half-automated verification of clearances, shapes, various sizes and floor-spaces of complex polygons. DFM-report normally provides the list of tiny inaccuracies fixing which makes the design looking just brilliant and fully ready for production.
To sum up, one of the principal approaches in the quality we follow says “first time right” which can be rephrased as “doing the best design from the very first attempt”. By accepting this idea and serving it EDALITY makes its partners feel safe about running the production of prototypes. Thus, we almost exclude the probability of “manufacturability” issues and minimize the necessity of running additional cycles of prototyping.
