ACI Technologies was contacted in regards to poor solder joint reliability. The customer submitted an assembly that was exhibiting intermittent opens at multiple locations on a ball grid array (BGA) component. The assembly’s functionality did not survive international shipping, essentially shock and vibration failures, immediately making the quality of the solder joints suspect. The customer was asked about the contract manufacturer and the reflow oven profile as well as the solder paste and surface finish used. The ACI engineering staff evaluated the contract manufacturer’s technique and determined that they were competent in the methods they used for placing thermocouples in the proper locations and developing the reflow oven profile. The surface finish was unusual, but not unheard of, in that it was hard gold over hard nickel, rather than electroless nickel immersion gold (ENIG). The customer was able to supply boundary scan testing data which showed a diagonal row of troublesome BGA pins.

Failure analysis (FA) is one of the key competencies in Intel. It enables very rapid achievement of world class manufacturing standards, resulting in excellent microprocessor time-to-market performance. This paper discusses the evolution of FA techniques from one generation of microprocessors to another.

Design workflow is the core to your design team's competitive advantage; it’s the conduit by which you turn your team's expertise and ideas into manufacturable products. And yet, all engineering teams face the challenge of maximizing their productivity within limited financial resources. How can the less-capitalized teams develop a design workflow that competes with the highly-capitalized teams? Simple: open tools.

The convergence of a wide range of global influences is having a profound effect on current-day quality in manufacturing. Today's operational strategies must take into account business cycles, risk-based management, logistics, workflows, outsourcing, regulatory issues, product development, corporate mergers and acquisitions. In this ever-changing economy it is imperative that companies compete more effectively on two fronts: by reducing costs and emphasizing quality.

Printed electronics is a familiar term that is taking on more meaning as the technology matures. Flexible electronics is sometimes referred to as a subset of this and the printing approach is one of the enabling factors for roll to roll processes. Printed electronics is improving in performance and has many applications that compete directly with printed circuit boards. The advantage of roll to roll is the speed of manufacturing, the large areas possible, and a reduction in costs. As this technology continues to mature, it is also merging with the high profile 3D printing. (...)This paper will show working demonstrations of printed circuit structures, the obstacles, and the potential future of 3D printed electronics.
