Reliability and Failure Mechanisms of Laminate Substrates in a Pb-free World

Especially with the new lead free solders, getting the correct temperature profile is more important than ever.

The plated thru hole has changed considerably in 50 years of electronic packaging, but in its many forms remains the most common interconnection in 1st and 2nd level electronic packaging, and is still one of the most feared in terms of reliability. The transition from the original solder filled holes to BGA wiring vias, subcomposite buried vias, and today�s microvias has resulted in many new failure mechanisms, not only in the copper interconnections but also in the surrounding laminate, especially with Pb free reflows.

Exposing the Myth: The Value of Branding in B2B Markets

A brand is the most important strategic asset your business will ever possess. Yet ask even the most experienced marketer and they will struggle to communicate the concept in a single sentence. Furthermore, if you were to approach the majority of today�s business-to-business organisations, they would probably tell you that branding finds little application in a market allegedly filled with dispassionate decision makers. However, an increasingly competitive market landscape is eroding this reality � if, indeed, it ever existed. B2B marketing must follow the example of its consumer-focused counterpart and embrace the notion that a strong brand has the power to differentiate, build and protect those it represents in the face of incessant commoditization.
