hear it from our customers

"A delightful company to work with. Could not have done it without your expertise."

"EI excels in responsiveness, support and flexibility. I very much appreciate EI’s ability to adapt on the fly."

"I appreciate the work EI does most of all because it makes my job easier."

"Overall, EI does a great job in dealing with everything we throw at them. They are responsive and understanding of us, even though it may not always be the most reasonable of requests. As a buyer, I feel lucky to have a supplier that works with us like they do."

"Working on a project that had a board that was simply not manufacturable the way it was set up, EI went above and beyond to help with engineering and still met a very short deadline."

PCB Engineering FAQs

  • What should be included in a PCB design for manufacturability review?

    A PCB design for manufacturability review should evaluate component footprints, spacing, polarity, solderability, panelization, thermal requirements, test access, and assembly constraints. We use DFM feedback to identify potential production risks before the design moves into manufacturing.

  • When should DFM be performed during PCB design?

    Complete DFM before releasing a design for production. Earlier collaboration gives engineering and manufacturing teams more opportunity to resolve component, layout, testability, and process concerns without creating unnecessary redesigns or schedule delays.

  • What PCB design files are needed for a manufacturing review?

    Provide the latest fabrication and assembly data, bill of materials, component placement information, drawings, test requirements, and applicable specifications. A complete release package helps us verify manufacturing intent and reduce engineering questions during new product introduction.

  • How can PCB engineering reduce manufacturing costs?

    PCB engineering can reduce total manufacturing cost by identifying difficult-to-source components, unnecessary process complexity, poor test access, assembly risks, and potential yield issues before production begins. The objective is a repeatable design rather than simply reducing individual component costs.
