Award winning designs: an interview with Peter Dill, 2007 winner of the Mentor Graphics PCB Technology Leadership Award.

Category: PCB design in the area of Telecommunication Switches, Network Servers, Base Stations and Computer Mainframes.

Company Name: IBM Zurich Research Laboratory

Designer: Peter Dill

Design Description: Controller board for a 64x64 port high performance optical switch

Soft-spoken and intense, Peter Dill is a senior engineer in I/O link technology for IBM Research GmbH in Switzerland. His design wowed in the Telecommunication Switches, Network Servers, Base Stations and Computer Mainframes category. He took a few minutes to talk to PCD&M about the PCB design that won him a PCB Technology Leadership Award earlier this year and where he sees the future challenges for designers.

The 36 layer board had 3,644 components, with a total pin count of 42,142. There were no embedded parts. The seven FPGAs had 1,704 pins. There was one FPGA with 1,020 pins; both were 1-mm pitch. There were 40 connectors with 285 pins each. The number of through holes was 9,188. The number of blind vias was 36,053. The number of nets was 12,954 with 29,246 connections. The number of differential pairs was 4,072 and the total trace length was 2.6 km.

To see the PCB design and hear what Peter Dill had to say about the design process or to learn more about the Mentor Graphics PCB Technology Leadership Awards, go to in PCD&M's online September issue. We will be featuring this and other award-winning designs through the end of 2007.
