SMDs in Medical Electronics: Just What the Doctor Ordered

Craig Hunter, Vishay Intertechnology, discusses the medical electronics sector. Recently, component manufacturers have stepped up interest in medical applications. The reasons aren’t difficult to discern. As reported recently by Databeans, there is no shortage of demand for better and more innovative medical equipment, and thus medical electronics has come to represent the fastest growing segment of the industrial market for semiconductors. Secondly, this growth has been quite robust with respect to the worldwide economic downturn. If that phenomenon seems counterintuitive, then consider that one of the key trends in reducing healthcare costs has been to shift the focus of care from hospitals and doctors’ offices to patients’ homes. This could only happen with advances in medical technology, mainly enabled by advances in the performance and reliability of electronic components.

Lead-free Solder Update

By Mitch Holtzer, Cookson Electronics - SAC alloys became the industry-standard lead-free solders after RoHS went into effect. Technical and economic factors are reducing the silver content in SAC compositions, with disadvantages like slower wetting speeds, and advantages like minimized BGA voids. Solder choices are influenced by the desired results, cost, BOM, and other factors.

Flux Chemistry for Lead-free SMT

By Edward Briggs and Ronald Lasky, Ph.D., Indium Corporation - SAC alloys have a higher melting point and exhibit poor wettability compared to tin/lead eutectic alloys. Flux chemistries are ever evolving to meet this changing environment. The purpose of this paper is to discuss the function of flux chemistry, acknowledging the general ingredients that make up most no-clean materials.

Undulating Coils Humanize PCBAs

Test Program Set (TPS) Migration: ROI for Functional Test Upgrade

Test program set (TPS) migration solutions address the problem of legacy automated test equipment (ATE) systems that support validation of military/aerospace systems experiencing end of life (EOL) issues. Robert Peet, SEICA, will review a cross section of ATE systems from both a hardware and software perspective, with specific emphasis on the challenges and solutions for test program sets using LASAR™ simulation. Migrating existing TPS from legacy systems* to current technology can be done at considerably reduced time and cost with modern TPS software migration tools. These allow for easy conversion and migration of functional test (FT) programs, with minimal debug. By retaining features such as guided probe, fault dictionary, and many others, test programs developed as far back as the 1970s are easily ported to state-of-the-art testers without losing functionality. Legacy programs can also be enhanced (post-migration) with new software tools. Modern migration tools, combined with hardware advances, can improve test coverage and diagnostic capabilities.

Tech Still Down: Inventory, Consumer Spending to Blame

By Jim McGregor, In-Stat - After a disastrous Q'04 to end 2008, it would seem that the high-tech industry had nowhere to go but up. However, the release of Q'01 results from several market leaders has revealed that up wasn't a direction we were headed. An inventory surplus affects semiconductor through PC companies, and consumer spending is still the critical driver for electronics demand.

Component Specifier

As SMT matures and its end products continue to shrink in size but grow in capability, manufacturers are constantly in need of components that satisfy demanding footprint, reliability and placement require-ments. Modern manufacturing techniques are useless if a board's components are out of date, perform poorly or fail to satisfy end-user requirements. To assist manufacturers in this search, SMT Magazine presents Component Specifier, a new product section designed to spotlight state-of-the-

Cleaning for Reliability Post QFN Rework

Mike Bixenman, Kyzen Corporation and Michael Konrad, Aqueous Technologies Corporation make an argument for removing flux residue under the quad flat pack no lead (QFN) post-rework, and present cleaning process options for meeting this cleaning challenge. The need for cleanliness under individual components increases as the spacing between connector leads decreases and power increases. The low stand-off height of QFNs traps flux between the ground pad and component leads. Flux trapped under the QFN is a reliability concern. The purpose of this research is to develop process knowledge for cleaning all flux residues from under the QFN device. The authors, representing cleaning material and equipment organizations, investigated process variables such as solder paste, cleaning agents, cleaning equipment, and wash process factors.
