Recent developments in No Flow-Fluxing Underfill (NFFUF) products have demonstrated their utility to enhance the reliability of flip chip assemblies with reduced processing steps over conventional capillary flow methods. This basic work considered processing conditions such as dispensed volume and placement force, speed and dwell time. Further evaluations of these new products on a variety of flip chip assembly configurations manufactured by various processes have been undertaken to provide further evidence of their suitability and potential in high volume electronic manufacturing. This paper summarizes the recent evaluations and discusses new studies of additional assembly configurations, which include higher input/output (l/O) counts up to full arrays in excess of 1200 l/Os.

As technology becomes increasingly reliant on electronics, understanding the reliability of lead-free solder also becomes increasingly important. This research project focused on phase transformation kinetics with the lead-free solder SAC 305. Today in the electronics industry, SAC 305 is the most widely used solder, making it a high priority to understand its long-term stability and performance in a variety of service conditions. Recent evidence has shifted the focus from thermal aging to reflow temperature and time above liquidus values during initial solder melting.

On September 14, 2010, the late Shannon Wren, owner of VisionTech Components ("VisionTech"), and Stephanie McCloskey, VisionTech's Administrative Manager, were arrested during the execution of search and seizure warrants issued against the pair by the United States government after evidence connected them to the sale of counterfeit parts to the U.S. Navy, defense contractors and others. A ten-count indictment charged McCloskey with conspiracy, aiding and abetting in violation of Title 18 United States Code, Sections 371 and 2; trafficking in counterfeit goods, in violation of Title 18 United States Code, Section 2320; and mail fraud, in violation of Title 18 United States Code, Section 1341. McCloskey pled guilty to conspiracy and aiding and abetting for her role in the scheme.

A customer contacted the Helpline with the concern that parts being used in their assembly may possibly be counterfeit components. The counterfeiting of electronics components is a world-wide problem, and the threat today is even more evident than ever before. Any company, large or small, that manufactures assemblies using electronics components is equally susceptible to using counterfeit devices in their assemblies. In most cases, counterfeit components aren't discovered until after the component has already been placed on a printed circuit board (PCB), usually during first article electrical test. At this point, the only recourse is to debug the circuit to determine the faulty component and rework each PCB already in production to replace the faulty component. As one might easily surmise, this is a rather costly process; world-wide, counterfeit components account for over $15B loss in sales annually!

Over the past several years, much research has been performed and published on the benefits of stencil nano-coatings and solvent under wipes. The process improvements are evident and well-documented in terms of higher print and end-of-line yields, in improved print volume repeatability, in extended under wipe intervals, and in photographs of the stencil's PCB-seating surface under both white and UV light. But quantifying the benefits using automated Solder Paste Inspection (SPI) methods has been elusive at best. SPI results using these process enhancements typically reveal slightly lower paste transfer efficiencies and less variation in print volumes to indicate crisper print definition. However, the improvements in volume data do not fully account for the overall improvements noted elsewhere in both research and in production.
