HERNDON, VA — iNEMI’s High-Reliability RoHS Task Force has published process and reliability guidelines for high-reliability electronics that may include both SnPb and Pb-free parts. Reliability concerns arise due to the differences in processing temperatures and materials.
RoHS5 modules (5 of 6 RoHS materials) are products that are RoHS-compliant, but contain Pb (under an applicable RoHS exemption). RoHS6 modules (6 of 6 RoHS materials) are soldered with Pb-free solder and are fully RoHS-compliant and Pb-free.
With current RoHS exemptions for high-reliability electronics, it is possible for assemblies to contain Pb and still be RoHS-compliant. Manufacturers taking the Pb exemption will continue to require SnPb-compatible components for their products, and may also use subassemblies, such as hard disk drives and power modules, that may or may not be Pb-free.
Thilo Sack, principal engineer, corporate technology, for Celestica and co-chair of the iNEMI High-Reliability RoHS Task Force, noted, “If RoHS6 subassemblies are to be used in RoHS5 products, the subassemblies should be thoroughly qualified to ensure that they will meet the higher reliability requirements of the RoHS5 products. Furthermore, in some cases solders and processes should not be mixed. For example, only BGAs with SnPb solder balls should be used in a SnPb assembly process, and only SAC solder balls in a SAC process.”
The task force recommends that Pb-free Sn finishes on leaded and discrete components only be used when these finishes (1) include suitable tin whisker mitigation practices, per IPC/JEDEC JP002, and (2) have passed Class 2 level tin whisker acceptance testing requirements, per JESD-201. For subassembly modules meeting RoHS5 or RoHS6 requirements, plated leads or pins that will be attached to the PCB should be backward compatible with SnPb assembly processes.

The task force consists of OEMs and EMS providers with long service life products and high-reliability requirements, including:
Agilent Technologies, Alcatel, Cisco Systems, Celestica, Delphi Electronics & Safety, HP, Intel, Jabil, Lucent, Plexus, Sanmina-SCI and Sun Microsystems.

FOSTER CITY, CA -- Arena Solutions, a provider of product lifecycle management software, and components distributor Avnet Electronics Marketing have signed a joint sales and marketing deal that covers both firm's tools and services.
Arena and Avnet will provide a complete, integrated on-demand PLM and component line that includes the latter's extensive component database -- said to number more than 19 million parts.
Avnet will make available purchasing data, and parametric and analytical data, along with documentation from IHS. The combined content database consists of rich data for over 19 million unique electronic components. and includes RoHS and environmental regulation information, product change notifications and part specification data.
Avnet content now can be imported directly into the Arena PLM tool.
Ed.: An earlier version of this story reported that IHS Parts Management would also be involved as a reseller. While Avnet Electronics and IHS have a partnership under which Avnet resell's IHS's content, Arena does not have a reseller agreement with IHS.

PALO ALTO, CA -- New analysis from Frost & Sullivan reveals that the worldwide SMT cleaning equipment market generated revenues of $34.3 million in 2005 and is likely to reach $55 million in 2012.
"Lead-free manufacturing has caused process changes in the SMT line that have placed more emphasis on cleaning," notes F&S industry manager Keith Robinson. "With more residue left on the assembly during lead- free manufacturing, industries that did not historically clean are likely to do so between 2006 and 2010, thus creating new market opportunities."
Pb-free manufacturing requires higher preheating and heating temperatures, causing changes in the flux that make it more difficult to clean. It also calls for an increased amount of flux, which leads to more residues on the assembly. Defects can occur in products if the assembly is not thoroughly cleaned, thus creating increased demand for SMT cleaning equipment.
Pb-free assemblies more difficult to clean, causing concerns among electronic assemblers about the feasibility of becoming Pb-free compliant in 2006. Moreover, cleaning Pb-free materials is highly demanding and places increased stress on the entire cleaning process.
"Some companies have been very proactive in educating customers on how to clean lead-free assemblies effectively," says Robinson. "SMT vendors will need to be very aggressive in addressing customers' needs in 2006, because this is a critical year for the SMT cleaning equipment market."

Apart from electronics manufacturing, the medical device, aerospace and defense industries are likely to increase their demand for SMT cleaning equipment. F&S predicts that these industries will be the primary markets for SMT cleaning equipment in North America and Western Europe. In China, the expanding space program is likely to provide new opportunities to equipment vendors.
Taunton, MA – Following its acquisition last year by HumiSeal’s parent company Chase Corp., Concoat Ltd. has changed its name to HumiSeal Europe Ltd.
The UK conformal coatings supplier has been manufacturing HumiSeal products for the European marketplace for over 25 years.
David Greenman, managing director, noted in a press release: “By operating in the USA and Europe under the same name, we make it crystal clear that we can offer a seamless transition between our manufacturing, sales and technical support services, with products that are tested and certified independently to military and automotive standards throughout the world.”

St. Charles, IL – Electra Polymers Ltd. has bought Rohm and Haas Electronic Materials’ inks business. The company will gain the Ronascreen inks and soldermask lines, as well as Durashield V42 thick copper technology filler products.
The acquisition, to be completed by the end of July, expands Electra’s portfolio of high-reliability coatings and gives it access to the heavy copper filler business.
Electra’s sales and marketing director, Shaun Tibbals, said in a release, “To remain competitive you have to put R&D effort behind your products. The Ronascreen product line has been developed over the years by leading, innovative companies such as Rohm and Haas Electronic Materials, LeaRonal, Morton, Shipley, Hoechst and now, through this acquisition, we are acquiring extensive levels of technological know-how.”
The acquisition involves the transfer to Electra of IP, product formulations and the existing global customer base.
Tibbals added, “While this does not give us new geographical markets, and although we already have a range of world-class soldermasks and inks for the PCB industry, it does give us access into new sectors."
