New Design Products (Nov 3, 2009)

Following are design software packages and upgrades that simplify, automate, and otherwise improve PCB design, design for excellence (DfX), and other aspects of new product introduction.

New Standard: IPC-2152 "Standard for Determining Current-carrying Capacity in Printed Board Design" (Oct 13, 2009)

IPC — Association Connecting Electronics Industries released IPC-2152, "Standard for Determining Current-Carrying Capacity in Printed Board Design." The 97-page document sets a standard for determining the appropriate sizes of internal and external conductors as a function of the current-carrying capacity required and the acceptable conductor temperature rise.

New Products for PCB Design and Device Programming (Aug 3, 2009)
(August 3, 2009) — These new PCB design and device programming products are focused on design for manufacturing (DfM), collaboration with MCAD mechanical design elements, fast in-system programming, and cost/performance analysis on circuit designs. Products featured come from PCB Matrix, Numerical Innovations, Vishay, Corelis, BPM, Zuken, and Screaming Circuits.
PCB Fab in a Recession: Lean, Web-based Ops (Jul 27, 2009)
By Pratish Patel, Electronic Interconnect (EI)
PCB fabrication is a competitive and price-driven business with slim margins. One U.S.-based supplier has a lean methodology to thrive and grow even in tough times. This article covers the fabricator's approach to business and the marketplace with the application of lean manufacturing principles and modern communications.
Board-level Thermal Management: 3D Heat Removal (Jul 12, 2009)
By Paul A. Magill, Ph.D., Nextreme Thermal Solutions
The paradigm driving PCB-level design has always been cost. However, IC-generated heat on these boards has increased in modern designs. Frequently, the heat generated by these die leads to hot spot formation on the circuit boards. As board designs progress, a combination of active and passive and bottom, top, and lateral thermal management is needed.
Thermal Management: The New Generation of CFD (Jul 8, 2009)

By Meredith Courtemanche, managing editor
Major design companies have released new thermal management solutions recently, prompting a look at the various technologies that can keep complex electronics functioning properly, regardless of their workload. Computational fluid dynamics (CFD) simulations are getting faster and more accurate.

Thermal Management Issues Resolved by Optimizing Airflow in Chassis (Jun 19, 2009)
By Chris Heard, Amphenol
This case study examines a leading-edge chassis design from the thermal management perspective. Through increasingly detailed simulation environments, the system designer was able to optimize airflow, verify the design's feasibility, and circumvent possible thermal problems as the design progressed.
PCB Designer's Notebook: Overcoming Imaging Challenges for High-density Circuits (May 19, 2009)
By Vern Solberg Designers often face increasing product functionality without the luxury of increasing board size. One option is implementation of a higher-density circuit interconnect solution. Laser direct imaging (LDI) efficiently transfers the circuit pattern directly onto a photoresist-coated panel, eliminating traditional photo tools. Benefits include time and costs savings, quality, and better registration than traditional contact printing fabrication methods.
