At ISI, we approach projects a little differently than most suppliers. We make sure not to apply a pre-engineered package family for each application, but rather are involved in a co-development process from concept all the way to production. We work best when we are deeply engaged with our customers at the early concept development stage and have the opportunity to learn what is most critical for their application.

To implement Next Level Integration designs, we have assembled a top-notch design and engineering team and invested in multiple manufacturing disciplines. Our design team of 70 degreed engineers (and growing!) has hundreds of years of experience in a wide variety of electronic interconnect challenges that can be leveraged to help make your application a success.

As a project-oriented company, we continually take on challenging projects that utilize a wide variety of packaging and interconnect technologies outlined below.
