This paper will focus on the application requirements of solder printing small aperture designs, concentrating on 008004 (inch) / 0201 (metric) size components, and the results of a design of experiment printing these challenging apertures. As Moore's law continues to be applied to component miniaturization, the next installment of reduced packaging has arrived in the form of the 008004/0201 for resistors and capacitors. Component size roughly the size of a grain of sand presents specific challenges to the solder printing process. To address these challenges, each aspect of the printing process will need be examined. This includes essential machine requirements, including correct squeegee blades, tooling support, and calibrations, to meet the demanding specifications. The correct match and design of materials will be addressed, focusing on the stencil and substrate design along with solder paste and cleaning solvent requirements. A design of experiment will be reviewed that applies the machine and materials discussed, including the printer and Solder Paste Inspection (SPI) setup and the specific machine parameters used. The results of these DOE's will then be closely examined.

These nano-coatings also refine the solder paste brick shape giving improved print definition. These two benefits combine to help the solder paste printing process produce an adequate amount of solder paste in the correct position on the circuit board pads. Today, stencil aperture area ratios from 0.66 down to 0.40 are commonly used and make paste printing a challenge. This paper presents data on small area ratio printing for component designs including 01005 Imperial (0402 metric) and smaller 03015 metric and 0201 metric chip components and 0.3 mm and 0.4 mm pitch micro BGAs.

The advance in technology and its relentless development is delivering yet another surface mount assembly challenge. To meet the market demand for products with higher functionality whilst reducing the overall product size, the next generation of chip package is being readied upon the surface mount community. The Metric 0201 will have dimensions in the order of 0.25mm x 0.125mm, as a result the entire assembly process will be questioned as to its ability to deliver high volume/quality product.

This technology transfer was prepared by the Research Triangle Institute (RTI) as part of SEMATECH's Facility Fluids Project (S100). It is a compilation of information on existing facility fluids metric and test methods. Information on standard methods was gathered from SEMATECH and SEMI. Other information was obtained from a literature search of journals and conference proceedings. The published information primarily is concerned with the test equipment used and what levels of detection and purity were found. Many of the articles discussed the use of new equipment, either commercial or experimental. Extensive annotated bibliographies are append to the report.

When designing PLLs in nanometer CMOS, it is essential to validate the closed-loop PLL performance metrics with nanometer SPICE accuracy before going to silicon. Transistor-level, closed-loop PLL verification has been impractical due to traditional SPICE and RF simulator performance and capacity limitations. By using Analog FastSPICE, designers dont have to trade accuracy for performance. Read this white paper to see how AFS: Delivers closed-loop PLL transistor-level verification Supports direct jitter measurements Produces phase noise results correlating within 1-2dB of silicon

The art of screen printing solder paste for the surface mount community has been discussed and presented for several decades. However, the impending introduction of passive Metric 0201 devices has reopened the need to re-evaluate the printing process and the influence of stencil architecture. The impact of introducing apertures with architectural dimensions’ sub 150um whilst accommodating the requirements of the standard suite of surface mount connectors, passives and integrated circuits will require a greater knowledge of the solder paste printing process.The dilemma of including the next generation of surface mount devices into this new heterogeneous environment will create area ratio challenges that fall below todays 0.5 threshold. Within this paper the issues of printing challenging area ratio and their associated aspect ratio will be investigated. The findings will be considered against the next generation of surface mount devices.
