PCB Design
When It Comes to CAD, Function Beats Speed
A veteran PCB designer's question – "What sort of data is
available to benchmark the top four CAD tools out there?" – sparks a huge survey and reveals some surprising answers.
by Chelsey Drysdale

TPCA Report

Reliability
Technical Diagnostics of Electronics Products: Application of Bayes Formula and Boltzmann-Arrhenius-Zhurkov
(BAZ) Model
For systems where failure-free operation is critical, technical diagnostics can recognize, in a continuous fashion and without dismantling, the ability to continue to function as expected over the long-term.
by Ephraim Suhir, Laurent BECHOU and Alain Bensoussan

PCB Design
7 Manual Routing Tips
Manual routing allows the engineer to apply all their experience to the design. An autorouter is an algorithm, and as such is limited in performing analysis or making decisions. But routing by hand, while time-consuming, can offer several advantages.

Procurement
Best Practices for Improving the PCB Supply Chain
PCBs should always be considered a critical commodity. Without stringent controls in place for board supplier selection, qualification and management, long-term product quality and reliability is neither achievable nor sustainable. Here are best practices and recommendations for improving your supply chain
by Cheryl Tulkoff and Craig Hillman, Ph.D.

PCB Design
Resolving EMI Effects in High-Speed Boards
The biggest effect EMI has on a design is that a product that doesn’t pass government requirements (FCC, for example) for radiated emissions cannot be shipped. But even if the product passes, and it is still radiating, it means reduced margins for signals and possible reliability issues – and usually increased susceptibility to outside noise. Most problems can be avoided simply by making sure all currents travel in a closed loop.
by Patrick Carrier

NTI-100
The 90-10 Split
Currency fluctuations had a big impact on the largest 104 printed circuit board manufacturers in 2011. Still, while making up less than 4% of the world's shops, the NTI-100 contributed more than 80% of the revenue.

CAM
CAM in the Cloud
A handful of PCB industry veterans are vying to be the first to offer pre-CAM analysis through the cloud. But will users prefers a pay-as-you-go model?
by Mike Buetow

Plating
Successful Formulation of ENIG Plating
As Pb-free solder can leave bumps on the traces during HASL (hot air solder leveling), many alternate surface finish processes have been investigated to overcome this challenge. Several formulations of ENIG plating have been tried. A successful formulation of ENIG in continuous use in volume production for more than two years is discussed.
