THE CHALLENGE

When a customer regularly requests a service which requires resources and costs being outsourced, there comes a point when you need to review the effectiveness of these processes. As industry demands for reduced RF noise grows, the need for testing and retesting our products during the stages of design have increased.

Allegro MicroSystems is an industry leader in the world of integrated circuit (IC) design. Its design and testing center in Manchester, New Hampshire, USA invests in testing to ensure that their developments deliver exactly what their customers need. However, this was becoming increasingly challenging using off-site services.

In 2014, Richard Garvey, Director of Systems Engineering at Allegro MicroSystems, decided it was time to review their testing processes. Richard explains: “We were increasingly reviewing the levels of EMC testing for our ICs in line with customer demands. The RF or EMC noise from end equipment can create issues in your home or car. To test and debug these we would often book an off-site facility for say 4 hours. Being off site we lost some of our resources for debugging so testing would not be quite complete. Then, a further 4 hour slot would have to be booked when perhaps we only needed another 40 minutes, which was a poor use of budget. Also, being off site, it wasn’t always convenient to travel to a testing facility, which was a 30 minute round trip.”
