American Standard Circuits is an early adopter of Averatek's A-SAP™ process for its ultra high definition interconnect (UHDI) products. I had the opportunity to sit down with industry veteran John Johnson to discuss this. John previously worked at Averatek and is now vice president of business development at American Standard Circuits where he over- sees quality. In the spirit of full disclosure, we will be discussing and sharing photos, slides, and materials with permission from both ASC and Averatek. Steve Williams: John, American Standard Circuits is a big RF manufacturer. Is there a big application for UHDI in that niche? John Johnson: Yes, absolutely. From a signal integrity side and getting that straight sidewall, it benefits a lot. But this technology works very well to produce very, very low surface profiles, and that's an additional benefit. When you look at just building boards with controlled imped- ance, you can get to a much tighter tolerance. We talk in the industry of typically ±10%, but we can do 5%, so this can get you down to a much tighter tolerance the first time out of the box because you're building right to the design. Your trace will be right there, and since you're UHDI FUNDAMENTALS: Talking UHDI With John Johnson, Part 2
