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."

Warehousing & Logistics FAQs

  • Can an electronics contract manufacturer manage inventory for an OEM?

    Yes. Inventory management can include purchased components, customer-supplied material, work-in-process assemblies, and finished goods. A defined inventory strategy can help OEMs coordinate manufacturing schedules and reduce the number of suppliers involved in the product lifecycle.

  • How can electronics manufacturing logistics reduce supply chain risk?

    Integrating component procurement, manufacturing, testing, finished-goods storage, and logistics with one manufacturing partner reduces handoffs between suppliers. It can also improve visibility into material availability, production status, and shipment requirements.

  • Can finished electronic assemblies be stored and shipped on demand?

    Finished-goods warehousing can support scheduled releases and customer-specific shipping requirements when defined as part of the manufacturing program. This approach can help align production quantities with downstream demand.

  • How does component obsolescence affect electronics inventory planning?

    Obsolescence can create availability, redesign, and lifecycle risks. Review product forecasts and component lifecycle status regularly so potential last-time buys, alternates, or redesign requirements can be addressed before they interrupt production.
