Bourns, Inc. was founded in 1947 by Marlan and Rosemary Bourns and has grown to be a leader in the electronics industry. The company designs, manufactures, and sells a variety of components, including sensors, resistors, and potentiometers.

What makes Bourns a great company to work for?

“Bourns is a company that believes in innovation starting with founder Marlan Bourns who invented trimming potentiometers designed to provide accurate circuitry adjustments. The world knows these products by our trademarked name, Trimpot®, and they are still being valued by engineers today as a way to fine tune the final design.”

“Another reason is Bourns is very strong in materials science and development. In my area we make almost everything ourselves; controlling all the materials from the ingredients to the finished product. For example, starting with basic alumina powder materials and using Bourns’ extensive resistive component fabrication expertise, we further process it to meet our strict ceramic product specifications. Our goal is to make components that remain stable in changing environments, especially for the aerospace and medical fields where the requirements are very specific.”

Thanh, tell us a bit about yourself

“I’m an electro-mechanical engineer, and lead the engineering team in the development of many Bourns products as well as being involved in the manufacturing process and related operations.”

What makes your work so exciting every day at Bourns?

“Our work with raw materials gives us the opportunity to experiment with different aspects like nano-materials, which helps to expand our research and drive new technologies. We recently worked with nano-platinum particles used in fuel cells and teamed with a local university on the study. These projects not only motivate the curiosity of Bourns engineers, but the science community, as well, and that was very exciting.”

What are nano-materials?

“Nano particles are 2-4 nanometers in size. (A sheet of paper is about 100,000 nanometers thick.) We built a membrane made out of these tiny particles and were able to generate electricity with the membrane by combining it with hydrogen gas to power a fan.”

Why should kids be interested in what Bourns is making?

“We have the opportunity to build products from beginning to end with the ability to touch on so many aspects of science and engineering. For me, it is very fascinating and challenging at the same time but also very rewarding when you come up with a solution.”
