Best Practices for Collecting Product Material and Compliance Data

Feb 23, 2017 | PTC

Managing the environmental performance of products is an increasingly complicated challenge for manufacturers today. These companies face a complex tangle of requirements and mandates from regulators, consumers and customers to manage the toxicity, recycleability and overall environmental impact of their products. Not only have governments, business-to-business customers and consumers demonstrated a clear preference for better environmentally performing and "greener" brands, but investors are now pressuring manufacturers, as well. For example, the Dow Jones Sustainability Index identifies and tracks leading sustainability-driven companies around the world.

This paper focuses on the challenges companies face and the best practices they can employ when collecting substance, material and compliance data from their suppliers and supply chain....

Component Level Reliability For High Temperature Power Computing With SAC305 And Alternative High Reliability Solders

Feb 16, 2017 | Thomas Sanders, Sivasubramanian Thirugnanasambandam and John Evans, Ph.D., Michael Bozack, Ph.D., Jeff Suhling, Ph.D. - Auburn University, Wayne Johnson, Ph.D. - Tennessee Tech University

This experiment considers the reliability of a variety of different electronic components and evaluates them on 0.200” power computing printed circuit boards with OSP. Single-sided assemblies were built separately for the Top-side and Bottom-side of the boards. This data is for boards on the FR4-06 substrate.

This paper was originally published by SMTA in the Proceedings of SMTA International....

Can Age and Storage Conditions Affect the SIR Performance of a No-Clean Solder Paste Flux Residue?

Feb 09, 2017 | Eric Bastow

The SMT assembly world, especially within the commercial electronics realm, is dominated by no-clean solder paste technology. A solder paste flux residue that does not require removal is very attractive in a competitive world where every penny of assembly cost counts. One important aspect of the reliability of assembled devices is the nature of the no-clean solder paste flux residue. Most people in this field understand the importance of having a process that renders the solder paste flux residue as benign and inert as possible, thereby ensuring electrical reliability.

But, of all the factors that play into the electrical reliability of the solder paste flux residue, is there any impact made by the age of the solder paste and how it was stored? This paper uses J-STD-004B SIR (Surface Insulation Resistance) testing to examine this question....

HOW MULTI-WAVELENGTH LED LIGHT IMPROVE CURING QUALITY

Jan 31, 2017 | DPL Industri A/S Denmark

Compared with general Mercury Lamp, normal LED can only provide a very narrow band. See the left side figure, which compare the output of a multi-wavelength( 365nm-410nm) LED lamp with traditional mercury lamp. At the same wavelength 365nm,LED lamp can output much more energy than traditional mercury lamp, means LED lamp can provide more high energy output in UV-A range. DPL eAsycure LED curing system use the latest LED technology on LED chip combination to reach high Joule Energy (DOSIS Energy), so it can easily cure UV ink in UVA range instead of single wavelength LED ink. According to our client’s ink performance, DPL LED Curing system can setup different output energy at different wavelength. If you have any question,please contact with our service team at dpl@dpl.dk or visit our website: www.dpl.dk...

Environmentally sound: Aqueous cleaning with minimum water consumption

Jan 23, 2017 | Connie Miede

"Water is not a problem of the future, but a key issue of our time for businesses: In the future, urgent water risks will increase in many areas of the world. A growing population, a changing consumer behavior and climate change will have an immediate impact on the availability and quality of water and thus build further pressure on governments, businesses and societies."

Rigid-Flex PCB Right the First Time - Without Paper Dolls

Jan 19, 2017 | Benjamin Jordan

The biggest problem with designing rigid-flex hybrid PCBs is making sure everything will fold in the right way, while maintaining good flex-circuit stability and lifespan. The next big problem to solve is the conveyance of the design to a fabricator who will clearly understand the design intent and therefore produce exactly what the designer/engineer intended.

Rigid-Flex circuit boards require additional cutting and lamination stages, and more exotic materials in manufacturing and therefore the cost of re-spins and failures are very much higher than traditional rigid boards. To reduce the risk and costs associated with rigid-flex design and prototyping, it is desirable to model the flexible parts of the circuit in 3D CAD to ensure correct form and fit. In addition it is necessary to provide absolutely clear documentation for manufacturing to the fabrication and assembly houses....

Effect of Alloy and Flux System on High Reliability Automotive Applications

Jan 05, 2017 | Mitch Holtzer, Steve Brown - Alpha, Marcus Reichenberger - Technische Hochschule Nürnberg

The July 2006 implementation of ROHS exempted automotive applications from converting to lead free technology. Nine years later, all major OEM and Tier 1 automotive manufacturers have converted or are in the process of converting to lead free circuit assembly processing. Starting with SAC (SnAgCu) alloys as a baseline for lead free soldering, in the last years several specific alloys were developed in order to improve resistance to high temperature creep, vibration survival and the ability to withstand thermal cycling and thermal shock.

The paper compares three different solder alloys and two flux chemistries in terms of void formation and mechanical / thermal fatigue properties. Void content and reliability data of the alloys will be presented and discussed in relation to the acceptance criteria of a Tier 1 /OEM automotive supplier. As a result, a ranking list will be presented considering the combined performance of the alloys. In order to analyze the void formation and mechanical behavior of different solder alloys and flux chemistry combinations, statistical methods are used....
