XRF- A Reality Check

Aug 14, 2008 | Sia Afshari

The Restriction of Hazardous Substances (RoHS) regulations of the European Union, and similar regulations being enacted around the world, require the virtual elimination of lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6), polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE) from electronic products. Allowable concentration levels in any homogeneous material contained within a product are extremely low: 0.01% for Cd and 0.1% for other substances by weight. The most significant issue affecting the practical validation of RoHS compliance in the day-to-day assembly environment is ensuring that no restricted substances, especially tin-lead (SnPb) materials, have inadvertently entered into the production stream....

Lead-Free Reliability - Building It Right The First Time

Jul 01, 2008 | Peter Biocca

As lead-free and RoHS compliancy fast approaches, it is more important than ever to build it right the first time. Lead-free assembly and RoHS will bring about numerous changes and the number of variables with which to contend is increasing, creating increased risk of defects and reduced product reliability. However, understanding what the variables are and their impact on the assembly can great increase product reliability....

Embedded Instrumentation: The future of advanced design validation, test and debug.

Jun 11, 2008 | ASSET InterTech, Inc.

The necessities that are driving the invention of embedded instrumentation arise from several imperatives. First, the speed and complexity of technology today, starting at the chip level, has escalated geometrically. Chip-to-chip interconnects and input/output (I/O) buses have blown past the gigabits-per-second (Gbps) and are pushing into the five to eight Gbps range. Moreover, the hundreds of millions and billions of gates now present on chips have increased the complexity of devices exceedingly....

Enterprise-wide Supplier Quality Management: The Big Payoff for Global SPC

Jun 04, 2008 | Zontec Inc.

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....

Solder Paste Inspection Technologies: 2D-3D Correlation

May 28, 2008 | Rita Mohanty, Vatsal Shah; Speedline Technologies, Paul Haugen, Laura Holte; Cyber Optics Corp.

This paper describes correlation between a true 2D area measurement (e.g. printer) and a height map generated area from a SPI system. In addition, this paper will explore the correlation between area/volume measurements and bridge detection between 2D/3D techniques. The ultimate goal is to arm the process engineers with information that can be used to make decision that will impact defects, cost, throughput and Return On Investment....

Printed Circuit Board Tracking with RFID: Speed, Efficiency and Productivity Made Simple.

May 07, 2008 | Chris Cook, Hank Tomarelli.

Tracking goods through manufacturing was originally accomplished with pencil, paper and human input. Barcodes introduced an automated, machine-readable tracking mechanism that streamlined all types of manufacturing. But modern printed circuit board (PCB) assemblies are running into limitations because of barcode labels. And though barcodes and RFID tags will co-exist, the relatively large barcode labels have to find increasingly scarce real estate on high density boards....
