Custom Coils: Your Partner in Innovation

Custom Coils prioritizes innovation and customer-centric solutions throughout the project lifecycle. We craft RF coil assemblies to your exact specifications, integrating your requirements into a unique manufacturing process solution that maximizes quality while minimizing costs.
Our partnership doesn’t end after a single project. We focus on building a long-term relationship and offering ongoing support for your current and future projects.

Design and Engineering Excellence

At Custom Coils, we pride ourselves on our design and engineering prowess. For every RF coil assembly, we gather design inputs and requirements from the client, using this information to confirm the design or make recommended changes. After multiple rounds of review, the client approves the final design, which specifies:

  • Turn count
  • Resistance / inductance / power data
  • Conductor selection
  • Lead orientation and terminations
  • Cooling components, if any
  • Finishing requirements
  • Physical/mechanical constraints of the equipment
  • And more

We design and engineer every custom RF coil for optimal manufacturability, ensuring the high quality and repeatability of the coil during production. This also helps reduce costs for the customer.

Prototyping Services

Our rapid prototyping services involve rigorous testing, validation, and iterative development, with an emphasis on client collaboration. We also perform various quality control processes, such as visual inspections, tooling fabrication, thermal modeling, pressure testing, and more. Throughout the process, we suggest design improvements to improve quality, cost, and manufacturability.

Advanced Manufacturing Capabilities

Our unique winding procedures and state-of-the-art manufacturing technologies are at the heart of our operations. Custom Coils specializes in producing high-quality, repeatable manufacturing processes for unique coil projects. Whether it’s a small batch or large-scale production, our scalability ensures that your needs are met with precision and efficiency.

What is an RF coil assembly and what does it do?

An RF coil assembly is a radiofrequency antenna that both transmits and receives signals in magnetic resonance systems. As a transmitter it delivers RF current to excite protons in the imaging field; as a receiver it captures the resulting magnetic flux and converts it into imaging data.

What are RF coil assemblies used for beyond MRI?

While MRI systems are the primary application, RF coil assemblies also play critical roles in semiconductor processing (RF match assemblies for ion implant and etch processes), telecommunications, and aerospace systems where precise signal transmission and reception are essential.

What design specifications does Custom Coils engineer into each RF coil?

Every RF coil assembly is engineered to exact specifications including turn count, resistance and inductance values, conductor selection, lead orientation and terminations, cooling components if required, finishing requirements, and the physical and mechanical constraints of the equipment it will operate within.

How does Custom Coils ensure the quality and repeatability of RF coil assemblies?

Their quality process includes 100% part and process tracking, first article testing, thermal modeling, tooling design and fabrication, pressure testing, and rigorous electrical and dimensional inspections. All assemblies comply with UL, NEMA, ISO 9001:2015, and ISO 13485:2016 standards.

Can Custom Coils improve on an existing RF coil design?

Yes. Throughout the prototyping and development phase, their engineers actively suggest design improvements to enhance quality, reduce cost, and optimize manufacturability, making them a true engineering partner rather than just a parts supplier.

How do I start a custom RF coil assembly project?

Contact Custom Coils or request a quote to begin. Their team will gather your design inputs and requirements, confirm or recommend changes through multiple review rounds, and finalize a design before moving into prototype and production.
