Hybrid Drying Technology for In-line Aqueous Cleaning of Lead-Free Assemblies

Jan 21, 2009 | Dirk Ellis

This paper describes a new approach to drying circuit board assemblies that significantly reduces the cost of ownership of an aqueous cleaning system. Drying performance is increased through a hybrid drying process that reduces energy input, exhaust requirements and sound levels. The combination of high temperature blow-off and convection brings the flexibility to tailor drying performance to fit the product's drying requirements....

Creating Solder Joint Reliability with SnCu Based Solders Some Practical Experiences

Jan 15, 2009 | Peter Biocca, Senior Market Development Engineer, Kester.

Tin-silver-copper has received much publicity in recent years as the lead-free solder of choice. SAC305 was endorsed by the IPC Solder Value Product Council in the United States as the preferred option for SMT assembly; most assemblers have transitioned to this alloy for their solder paste requirements. The SAC305 alloy due to its 3.0% content of silver is expensive when compared to traditional 63/37 for this reason many wave assemblers are opting for less costly options such as tin-copper based solders for their wave, selective and dip tinning operations....

Cleaning High-power Electronics

Jan 06, 2009 | Steve Stach, Austin America; Harald Wack, Ph.D., Naveen Ravindran, Zestron America; Joachim Becht, Zestron Europe

To prevent malfunctions in high-power electronics, flux residues must be removed from flip chip components prior to subsequent processes. As a result, integrating a suitable cleaning application into the manufacturing process of flip chip components is often required. Solvent based applications have re-emerged, and with that, an overall process solution is necessary....

An Experimental and Computational Study of the Current Carrying Capacity of High Performance PWB Interconnections

Jan 01, 2009 | Michael J. Rowlands and Vara Calmidi, Endicott Interconnect Technologiesogies

Recent technology advancement has enabled enhancement in PWB electrical performance and wiring density. These innovations have taken the form of improved materials, novel PWB interconnect structures, and manufacturing technology. One such advancement is Z-axis conductive interconnect. The Z-interconnect technology involves building mini-substrates of 2 or 3 layers each, then assembling several mini-substrates together using conductive paste....

Fuel Cell Production Revs Up. The Paste Printing Platform And Process Has Other Uses, Too.

Dec 18, 2008 | Clive Ashmore, Global Applied Process Engineering Manager; DEK.

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....

Bromide-Free Options for Printed Circuit Boards

Dec 11, 2008 | Craig Hillman, PhD & Seth Binfield

Flame retardants have been around since the Egyptians and Romans used alum to reduce the flammability of wood. Brominated flame retardants (BFRs) first experienced use after World War II as the substitution of wood and metal for plastics and foams resulted in materials that were much more flammable. The widespread use of BFRs initiated in the 1970s with the explosion of electronics and electrical equipment and housings. For the US market, all of these products must conform to the UL 94 flammability testing specifications. In fact, the most common printed circuit board (PCB) in the electronics industry, FR-4, is defined by its structure (glass fiber in an epoxy matrix) and its compliance to UL 94 V0 standard....

Broadband Printing - A Paradigm

Dec 03, 2008 | Arun S. Ramasubramanian, Dr. Daryl Santos; Suny Binghamton.

This paper presents the analysis from a recent printing study employing a test vehicle that includes components such as 01005s to QFPs. In a recent publication, part of this study was presented focusing on 01005 printing only. This printing process was determined to be suitable for 01005s assembly and also analyzed based on statistical capability. The current paper will present the results from additional detailed analysis to determine if this process has the capability to provide sufficient solder paste deposits for larger components located on the same test board. In the future, the SMT industry may always look towards “Broadband Printing” as an alternative to dual stencil or stepped stencil printing technologies in order to meet the needs of both small and large components....
