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

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.

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.
