DFM Review

EI Microcircuits has a design-oriented philosophy to achieve the highest quality results. EI’s DFM (design for manufacturability) process has a proven track record of product improvements and successful product launches. Project engineers perform DFMs incorporating years of experience and applying the latest software tools. Then our closed loop NPI process provides design feedback after the build.

CAD Design – Board Layout

EI Microcircuits excels at board layouts using Altium as our schematic and layout software. Our design library has been developed around proven quality results in manufacturing. Therefore, effective DFM requirements are incorporated into the design from the start.
