Reflection of 2016

Letter from the President:

Coming into the new year, our prospects are brighter than ever.  The marriage of our employees and our customers has strengthened the success of our company.  We have always pursued a goal of hiring the best possible people for any job and training them carefully.  And we have always placed our customer’s needs first. Each and every employee understands that our priority is to deliver industry leading service, on-time delivery and quality to every one of our customers.

Since our founding in 1974 our business has evolved from being a build to spec coil winding house, to a company that is a technology leader, and provides products and services with value added engineering content.    This is the future of our company.   We maintain an active research and development effort.  We will continue to support and grow the build to spec business, but this will be married to our businesses of engineered product development and value added services.  We see them as complementary.

As a family owned, private company, we have the luxury of focusing on our long term goals.  This long term focus is essential to our position of industry leadership.  We have the patience to work on the development of technology for the next generation of magnetic components, we are able to stock KanBan for our customers, we pursue our vision of quality manufacturing and technology leadership, not a quarterly profit goal.

In the last few years our business has grown rapidly, and next year we will be making some enhancements to accommodate the growth needs of our customers.  A few of the changes we are implementing now include: 1.) expansion of our Stockton, California facility and retrofit of our Mexico facility, 2.)  company wide implementation of ISO 13485:2016 and ISO 9001:2016,  3.) additions to our engineering staff,  4.) expanded production and test capabilities.

We would not be where we are today without the contribution of our employees.  They are the foundation of our success.  Their actions, however small, are what make our company great.  It is of the greatest importance, and important to me personally, that they be treated with respect and dignity, and are welcome every day in a safe and clean work environment.

-Weyman Lundquist, Head of Engineering at West Coast Magnetics


See you at APEC 2017

APEC allows power electronics professionals from all sectors to gather annually and participate in a rewarding exchange of technical knowledge, gaining valuable industry connections. 2016 APEC Conference in Long Beach was a unique experience establishing new partnerships. Professor Charles Sullivan from Thayer School of Engineering at Dartmouth hosted a chalk talk at our booth on High Frequency Winding Losses. The turnout was successful with scholars, engineers and industry leaders lined up at our booth for the Chalk Talk. If you missed the event you can download the information presented here Chalk Talk – by Professor Charles Sullivan on High Frequency Winding Losses.

Come join us in March in Tampa Florida for APEC 2017 at booth 1738. We will host another Chalk Talk with our President Weyman Lundquist. Ask your sales representative for more details or to schedule a meeting. I look forward to seeing you at APEC!

Another step in the right direction

We are proud to announce IPC-610 certification for the shop floor supervisors, quality staff and management of our facility in Tecate, Mexico.

This training was undertaken in order to advance our goal as a manufacturing quality leader in our industry, serving our customers in the medical device, aerospace, and test and measurement industries.


Introducing Mary Clark


My name is Mary Elizabeth Clark, and I am a new research and development engineer at West Coast Magnetics. I began working here in mid-October, and as a new hire I thought I might write an introductory post about myself.

I finished my B.S. in Physics at UCLA in June 2016. When many people think of physics, they think of projectile motion and gravity, but my personal favorite subject in physics is electricity and magnetism. I chose my electives to focus on this subject, with theoretical courses in plasma physics and laboratory courses in electronics and plasma physics. I participated in research at UCLA’s Basic Plasma Science Facility in my junior and senior years; I worked on many projects but mainly I studied low frequency plasma waves called Alfvén waves. I received a scholarship in my senior year to pursue this research by writing an experimental proposal, carrying out the experiment, and presenting the results in a poster and thesis. I presented posters three times as an undergraduate, winning the Dean’s Prize Medal of Excellence for my final poster at UCLA’s Research Poster Day in May 2016.

mary-2-2At West Coast Magnetics, I will apply my physics knowledge and research skills to develop innovative new products. I will use physical models to predict the qualities of a product. I will test it thoroughly, changing the design as necessary to fit your specifications and documenting results to evaluate the effects of different parameters. I will find the limitations of the physical model when implemented in real life. Through modeling and experimentation I hope to make our designs more predictable and less based on a trial-and-error.

If you wish to contact me directly, my email is, and my phone numbers are 800-628-1123 (office), or 209-662-8642 (cell). I am excited to work for West Coast Magnetics!

Bonded Coils

At West Coast Magnetics we are industry leaders and we constantly seek ways to make the impossible seem possible. WCM has extensive experience in manufacturing bonded coils. We have pushed the limits and experimented with bondable wires up to 43 gauge. From cylindrical shaped inductors at 6″-12″ in diameter to even the most minute designs at 4mm diameters, they can be done. Our team will make it happen

WCM’s 3D Capability

While committing ourselves to providing customers the best electrical solutions, WCM also possesses the skills and resources to customize mechanical fixtures and mounts for your special needs. Integrating our 3D CAD skills and rapid prototyping technology, our team is capable of designing mechanical parts via 3D CAD based on your dimensional requirements. 3D printed mounts assembled with electronic parts can be made with a short turn-around time during your prototyping stage. 3D step files of the product can also be provided upon request for customer’s 3D assembly usage.
