8 PCB007 MAGAZINE I MARCH 2022 Nolan's Notes by Nolan Johnson, I-CONNECT007 Materials & Technology It didn't start with Forrest Gump—the idea that two things (or people) go together "like peas and carrots"—but that line from the movie certainly has been appropriated by Tom Hank's character in the film adaptation of the Winston Groom novel. As this issue of PCB007 Magazine came together, our edito- rial staff couldn't seem to shake off the image of the vegetable combination when it came to materials and technology. So, we're picking up on the ongoing devel- opment of new base materials for PCB fabrica- tion. We all see and feel the changes in dynam- ics that are influencing materials; our manufac- turing capabilities are being pulled in multiple directions simultaneously. Some characterize it as a fracturing, others see it as an opportunity. I guess it depends on where you stand in the sup- ply chain. We're opening the doors to the mate- rials' research departments to discuss the ever- tightening relationship between the product's application and the material selected to serve as the PCB substrate. For those who are designing boards for spe- cialized, higher-performance applications, the choice of materials with optimized perfor-
