Signal Integrity Issues and Printed Circuit Board Design Douglas Brooks
Publisher: Prentice Hall International

So although the package and your clock speed have not changed a problem may exist for legacy designs. They can carry signals or power between layers. This article presents a brief overview of board level simulation for high-speed, multilayer PCB design and highlights some common traps and some tips so hopefully you get it right first time. I don't know of a good reference that addresses all the issues. Innovative Signal Integrity & Backplane Solutions (by Bert Simonovich) PCB Vias – An Overview. For backplane designs, the most common form of Smaller vias and tighter pitch driven by large pin count BGA packages makes back-drilling impractical in these applications; due to drill bit size and tolerance issues. Success in electronic design often hinges on running simulations. Its low dielectric constant and low dissipation factor make it an ideal candidate for broadband circuit designs requiring fast signal speeds or improved signal integrity. PCB design is mostly about signal integrity, controlled impedance lines, EM coupling, and supply decoupling. We may perform Even so, finding a problem early in the design cycle using post-layout simulation is still orders of magnitude less expensive than trying to fix a shipping product. Whether signal integrity, power integrity, electromagnetic compatibility, analog, or even thermal simulations, they reveal information about design feasibility, margins, and limitations. In actual production environments and industry, PCB design and signal integrity issues like impedance mismatch are done and checked using software like PADS and Allegro. All of this innovation presents a serious challenge to the PCB designer, who must now take into account parasitic effects and EMI issues that can impact signal integrity and cause circuit failure.
