The HDI Handbook now available for downloading The HDI Handbook is a comprehensive resource on high-density interconnect technology for end-users, designers, and fabricators. You can read a short review of the entire book and download a free copy from www.hdihandbook.com.  A quick summary of Chapter Four, contributed by Dr. Bogatin, follows below.   Summary of Chapter Four: Electrical Performance The good old days of 10 to 16 MHz clock frequencies are gone. It used to be the chief design challenge in circuit boards or packages was routing all the signals in two layers and getting packages that wouldn’t crack during assembly. The electrical properties of the interconnects were not important because they didn’t affect system performance. But the world has changed in the past 10 years. Clock frequencies on chip now are over 3 GHz, and on board, are over 800 MHz. In most systems, as the clock frequency goes up, the rise time always gets shorter. A shorter rise time means signal integrity problems increase dramatically. Signal integrity is broadly concerned with the problems that arise from how the electrical properties of the interconnects and power distribution affect system performance. External signals can affect noise as well as the return path for signals along planes. HDI provides miniaturization, smaller and shorter vias, shorter interconnect lengths with smaller parts and finer pitch devices, thinner and lower dielectric-laser drillable dielectrics and embedded components. These can be enabling techniques for improved high-frequency electrical performance. www.hdihandbook.com   EE Times Interview for New Science Fiction Novel by Dr. Eric Bogatin Rick Merritt at EE Times has published an interview with Eric about his new Science Fiction novel.  Titled "Shadow Engineer" it's now available through Amazon.  Check it out and let Eric know what you think!

PRESS RELEASE - SEPT. 5, 2008 - Professional Certification Announced Bogatin Enterprises Partners with IEEE Educational Programming   OLATHE, KS -- Bogatin Enterprises and the IEEE (Institute of Electrical and Electronics Engineers) announce a Professional Development Certification Program in conjunction with the IEEE’s Educational Partner’s Program. This partnership expands the offerings of Bogatin Enterprises and beTheSignal.com, providing a series of signal integrity and electrical design focused certification programs that cover the latest in high-speed design, simulation and modeling techniques. In January 2009, this collaboration will create a new learning platform that combines traditional classroom education opportunities with a strong distance-learning program that will facilitate access for signal integrity engineers world-wide. Through this program, discounts for the Bogatin Enterprises Professional Development Certification Program will be available for all IEEE members. The IEEE is partnering with providers from academia and corporations to provide the IEEE membership the most effective learning resources. The Partners are a carefully selected number of universities and corporations reviewed and approved by highly qualified IEEE volunteers. “We’ve been growing our course content through traditional classroom training and distance learning for several years”, stated Susan Bogatin, Chief Operating Officer.  “Partnering with the IEEE Education Partner’s Program allows us to have the perfect vehicle for providing a comprehensive Certification program to enhance the careers of signal integrity engineers.” About Bogatin Enterprises, LLC For 20 years, Bogatin Enterprises has been a leading provider of signal integrity training.  They offer a full curriculum of on-site and public classes and, through BeTheSignal.com, offer web-based training, online lectures, application notes and feature articles. Subscriptions are available for individuals, small groups and at the corporate level.  Contact them at info@BeTheSignal.com PRESS RELEASE - July 2008 - New Blog by Dr. Eric Bogatin PRESS RELEASE NEW BLOG IN PLACE AT BETHESIGNAL.COM Learn what Dr. Bogatin has learned this month Olathe, KS – July 3, 2008 – Bogatin Enterprises and beTheSignal.com announce the release of a new blog hosted by Dr. Eric Bogatin .  "What I've Learned This Month" features topical issues related to signal integrity.  An important feature of this blog will be to identify future technology advancements for signal integrity engineers, and break down the barriers to understanding. "During 2008, our development efforts have been focused on building our educational content", states Susan Merys Bogatin, Chief Operating Officer.  "We consider this blog to be an important component in our attempt to reach SI engineers with the most current information available, in a format that's easy to understand".
