Only U.S. Fabricator CertifiedAs of 2014, SEC was the only US PCB fabricator certified to Delphi's C7000 Class C certification for On-Engine applications. We are certified up to 10 layers and down to 6 mil finished hole size.
Due to Delphi's strict performance requirements, IPC Class 3 standards do not fully encompass PCB characteristics required to survive long-term in high temperature thermal cycling environments. As such, Delphi formulated the C7000 certification program to address this.
Among other tests, the most grueling is a 1000-hour thermal cycling requirement on a daisy chain coupon. Each coupon contains a series of vias linked through plated vias and inner layer connections. Vendors are tested on layer count and minimum via diameter. Testing is performed using two air-to-air test chambers, after which it must exhibit less than a 10% change in resistance.
Saturn has passed the Class C On-Engine certification which requires thermal cycling from -40 °C to +145 °C.
