Testing Digital Designs – The Boundary-scan Balance

May 20, 2010 | James Stanbridge, Steve Lees

As several industry pundits have expressed in recent years: "the era of 'one test method fits all' seems well behind us." For most test managers with even a modest mix of products, trying to formulate a test policy/philosophy has become a tricky balancing act at the best of times. James Stanbridge, Sales Manager UK for JTAG Technologies, and Steve Lees Managing Director of ATE Solutions look at the options....

Leaded and Lead-Free Solder Paste Evaluation Screening Procedure

May 12, 2010 | Ronald C. Lasky, Ph.D., PE; Indium Corporation of America Daryl Santos, Ph.D., Aniket A. Bhave; Binghamton University

Numerous studies have shown that greater than 60% of end of line defects in SMT assembly can be traced to solder paste and the printing process. Reflowing adds another 15% or so. In light of this fact, it is surprising that no simplified procedure for solder paste evaluation has been documented. This paper is about such a procedure....

Effect Of Board Clamping System On Solder Paste Print Quality

May 06, 2010 | Dr. Rita Mohanty; Speedline Technologies, Rajiv L. Iyer, Daryl Santos; Binghamton University

Stencil printing technology has come a long way since the early 80’s when SMT process gained importance in the electronics packaging industry. In those early days, components were fairly large, making the board design and printing process relatively simple. The current trend in product miniaturization has led to smaller and more complex board designs. This has resulted into designs with maximum area utilization of the board space. It is not uncommon, especially for hand held devices, to find components only a few millimeters from the edge of the board. The board clamping systems used in the printing process have become a significant area of concern based on the current board design trend....

An Effective Design of Experiment Strategy to Optimize SMT Processes

Apr 22, 2010 | Ronald C. Lasky, Ph.D., PE, Professor Daryl Santos, Ph.D., Joseph R. Cloyd

It is now widely accepted that using designed experiments is the most effective way to optimize surface mount technology (SMT) processes. This situation begs the question "what is an effective strategy in implementing this powerful tool?" This paper will present such a strategy that incorporates Taguchi's approach for screening, full factorial analysis for optimization and central composite design for precise modeling. We will present these techniques using MINITABTM Release 13 statistical software and printed circuit board industry applications....

Ceramic to Plastic Packaging

Apr 15, 2010 | Michael D. Frederickson, EMPF Director; Barry Thaler, Ph.D. EMPF Technical Director Empfasis Technical Editor; Paul Bratt, Empfasis Editor.

As electronic products increase in functionality and complexity, there is an emphasis on affordability, miniaturization, and energy efficiency. The telecommunications, automotive, and commercial electronic markets are the leading drivers for these trends. These markets see high volume manufacturing with millions of units priced to the fraction of the cent. The choice of the packaging material for the electrical components for these markets can have a substantial effect on the cost of the final product. Therefore plastic encapsulated components are almost universally used in non-military applications over the conventional ceramic or metal electronic packages....

Thick Film Polymer Resistors Embedded in Printed Circuit Boards

Apr 15, 2010 | Lynne Dellis, M S Chan, Tom Dueber, Shane Fang, John Summers; DuPont Electronic Technologies

The high level of current interest in embedded passives in printed circuit boards is driven by the tremendous pressure to pack more circuitry into smaller spaces. However, adoption has been limited due to design, prototyping and infrastructure issues, as well as the stability and tolerances necessary for widespread replacement of discretes. The focus of this work has been to develop a polymer thick film resistor technology to incorporate reliable organic resistors inside printed wiring boards using standard PWB processing....
