Solder Phase Coarsening, Fundamentals, Preparation, Measurement and Prediction

May 07, 2009 | Crina Rauta, Dr. Abhijit Dasgupta and Dr. Craig Hillman, DfR Solutions.

Thermal fatigue has been one of the most serious problems for solder joint reliability. Thermo-mechanical fatigue failure is considered to be closely related to micro-structural coarsening (grain/phase growth). Factors that influence the phase growth are studied and measurement methods are discussed, including the preparation of the eutectic solder sample for phase size measurement. Three categories of models used to predict grain growth in polycrystalline materials are presented. Finally, phase growth in solder during high temperature aging and temperature cycling and its use as a damage correlation factor are discussed....

Exposing the Myth: The Value of Branding in B2B Markets

Apr 30, 2009 | Protean Marketing Inc.

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....

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

Apr 30, 2009 | Kevin Knadle.

This presentation surveys the most significant via and via-related laminate failure mechanisms from past to present using data from current induced thermal cycling (CITC) testing, failure analysis, and other sources. The relative life and failure modes of thru vias, buried vias, and microvias (stacked vs. non-stacked) are compared, along with the affect of structure, materials, and peak temperatures on the above. The origin of via-induced laminate failures such as "eyebrow cracks" and Pb free related internal delamination is also explored....

SMT Preventative Maintenance: Nozzles

Apr 23, 2009 | Zach Shook, Marketing Director; Count On Tools, Inc.

No SMT equipment can place accurately and run efficiently without quality nozzles and feeders. These two factors are the core of the pick and place process. If the machine is either unable to pick parts consistently or hold on to the components during the transport from feeder to PCB, defects will result. ...

How to Profile a PCB

Apr 22, 2009 | P. John Shiloh, John Malboeuf.

An optimal reflow profile is one of the most critical factors in achieving quality solder joints on a printed circuit board (PCB) assembly with surface mount components. A profile is a function of temperatures applied to the assembly over time. When graphed on a Cartesian plane, a curve is formed that represents the temperature at a specific point on the PCB, at any given time, throughout the reflow process....

Mar 27, 2009 | Dr. Benlih Huang, Dr. Hong-Sik Hwang, and Dr. Ning-Cheng Lee; Indium Corporation of America.

The Sn-Ag-Cu (SAC) alloys have been considered promising replacements for the lead-containing solders for the microelectronics applications. However, due to the rigidity of the SAC alloys, compared with the Pb-containing alloys, more failures have been found in the drop and high impact applications for the portable electronic devices, such as the personal data assistant (PDA), cellular phone, notebook computer..etc...

Ten Steps Toward More Successful Projects

Mar 25, 2009 | Mike Weekes.

Have you ever been asked to lead a project to fix a problem, implement a new technology or some other initiative? It can be intimidating. Just because you, yourself are a good problem-solver, doesn't mean you have the capacity or drive to work with a team to achieve a goal. Often the secret to success lies in up-front preparation. Here are ten things you can do to help assure that when the project is done, it will have the effective results your leadership team is looking for....
