Electromagnetic Engineering Design & Prototyping Services

Electronetics offers an array of technical and engineering services to complement our manufacturing. We are experts in all areas and applications of electromagnetics, including high power electronics, audio, power supplies, digital electronics, materials, RF and microwave, to name a few.

We will work with your engineers and designers to create custom designs, design modifications, retrofits to existing equipment or to tailor an existing design to new requirements or applications. Our custom magnetic simulation software and CAD software enables us to make advanced designs in a reasonable timeframe. We can recommend optimal materials to improve performance or to replace an obsolete material.

Electronetics has full prototyping and testing capabilities to ensure that we meet or exceed our customer's specifications.
