1000 units per day) production environment presents challenging technical, logistic and cost obstacles that are usually more complex than those encountered at the inspection (automated optical inspection) and the manufacturing process test step (in-circuit test).

A student competition paper at Budapest University of Technology And Economics, Department of Electronics Technology gives background, covers stencil design and discusses stencils intended for pin in paste application. The stencil applied for depositing the solder paste is a thin, 75–200 µm thick metal foil, on which apertures are formed according to the solder pads on the printed circuit board. Stencil printing provides a fast, mass solder paste deposition process; relatively expensive, appropriate and recommended for mass production.

Lowering inventories is one of the quickest ways to decrease working capital needs. Performance measurements, such as the old standby ROA (return on assets) and the newer EVA (economic value added), as well as other measures that gauge how efficiently capital is used, have become more common organizational drivers. In fact, many an executive’s bonus depends, at least in part, on how efficiently capital is used.

While the origin of the phrase "may you live in interesting times" is widely disputed, the fact that we indeed live in an interesting time is certainly not. While record bank failures and declines in stock values, only rivaled by the Depression era, wreak havoc on consumer confidence, the economic trickle-down effect translates to reductions in production output and ultimately the consolidation of many industries, including electronic assembly.

With regard to potting, the design of electronic assemblies and components has a significant impact on economical and sustainable production. Key aspects in this respect are pottability, material use, cycle times, quality and the process technology needed. Optimized, bubble-free potting contributes greatly to the function and longevity of products. It is best practice during the design and development phases therefore to follow the potting tips contained in this White Paper.

On January 1, 2015, nine months from APEX 2014, the production and use restrictions on HCFC-225 will be in effect throughout the United States. This phase out is encompassing in scope. This phase out will have significant technical, performance, and economic implications for the electronics industry. The regulatory situation remains fluid. A number of alternative solvents have been or are in the process of being developed. We discuss the options for assemblers and component manufacturers.

As silicon technology advances to enable higher density ASICs, the core logic voltage decreases. The lower voltage, in combination with higher current requirements, requires tighter tolerances on the power supplies. The control of the power supplies from the PCB to the die is the subject of this study. A frequency sweep simulation using typical bypass values shows that a discrete package capacitor is not a significant factor in reducing the chip core power supply fluctuation. A small voltage boost at the PCB supply can provide a more economical solution to managing the device supplies.

Nano-coatings have been introduced by various manufacturers, with the promise of addressing some of the challenges relative to solder paste printing. Stated benefits include: Reduced underside cleaning, reduced bridging, improved solder paste release and improvements in yield. With several nano technologies already on the market and more likely to be introduced, how can the performance be quantified? How robust are these coatings? How can an assembler approach the ROI of these coatings? What hidden benefits or negative impacts should be considered? This paper will present a rigorous method for evaluating the performance and economic benefits of solder paste stencil nano-coatings.

Unless you've been living under a rock the past several years, you are no doubt keenly aware of the global drive toward alternative energy sources. Certainly this initiative is attractive because of the clear environmental benefits of developing fossil fuel substitutes, but also because of potential economic benefit. Although fuel cell technology has been proven viable for various applications, the production costs still remain relatively high, and further process development to promote low-cost, high-volume manufacturing is required to reach a price point that encourages widespread consumer acceptance.

There is much to read about the shifting sands of electronics manufacturing, including current moves by OEMs to alter their EMS relationships to better mitigate risk and cost, while EMS companies look for additional ways in which to adjust their business models in an attempt to improve their profitability. Electronics outsourcing over time evolved from a means to buffer manufacturing demand fluctuations into a wide scale shift in capabilities, in part in order to deal with vastly shorter product life cycles. Following the global economic crash of 2000, aka “the internet bubble,” more and more EMS providers responded by transferring their manufacturing to low cost labour regions, and in particular China.
