In 2004 we will bring a new product in Europe to the market. Does anyone have experience with leadfree designs? Will our product need to be leadfree by 2004?? Where can I get some information??
I know a lot of questions for a new member :-).

Claudia,

Lead Free is a marketing ploy. When a Japanese company announced that they had converted their product to "Lead Free" they sold more units. Now Japan is on a ban of products that contain lead. They want to become a "Lead Free" country (so does Europe).

The big thing is IPC has publicly stated that there is no apparent harm in Lead solder on printed circuit boards. There is no health or environment risk. But that doesn't change Legal legislation regarding the ban of products containing Lead in Europe and Japan. Both nations are scheduled to implement a "Ban on Lead Products" starting January 1st 2004. How strictly this will be enforced or even if it will become law is still up in the air.

All the manufacturers of fabrication and assembly equipment are up in arms. Companies that sell Immersion White Tin lines are blasting the HASL lines with rhetoric and hype so they can sell more of their equipment. They are making statements that are persuading the elimination of lead in solder like any underdog competitor would.

Bottom line is that this subject is under great debate, but my personal feeling is that "Lead Free" will win out. So I would look for alternatives to lead.

Right now you can purchase Silver Plating at Hallmark Circuits cheaper than "Hot Air Solder Leveling" (HASL). At TYCO you can purchase Nickel/Gold (NiAu) plating cheaper than HASL. There are several companies now that sell "Lead Free" solder for assembly. Talk to anyone at Plexus. So you really do not have any problems eliminating solder from your processes.

The person with some great insight information on this entire Lead Free debate is Tom Scimeca, Ph.D. of Florida CirTech, Inc. Office: 949.389.9995 or Cell: 949.678.2224 or e-mail: tomscimeca@aol.com. Tom sells Immersion White Tin Line equipment to manufacturers and keeps up to date with the "Great Lead Free Debate"

Claudia,

I just read in the June issue of Printed Circuit Design - Page 29.

It's an article regarding "The Quest for the Ultimate Board Finish".

The European Commission is leading the world to make the electronic industry "greener". They are imposing restrictions on the Europeon electronics industry and their suppliers to eliminate lead in their products by 2008. Many legislators around the world are pursuing the same. This makes the HASL (Hot Air Solder Leveling) board finish questionable in the near future.

From this article it seems that Europe has pushed back it's agressive 2004 mandate till 2008.

Tom and Claudia,

I was talking to one of our board vendors a while back. In 1982 he was told that in FIVE YEARS there would be no lead in PCBs. Twenty years later we're still hearing essentially the same thing.

On the other hand, Oregon banned the sale of regular leaded gasoline because of the lead content even though "leaded" gasoline hasn't had lead in it since the late seventies. So here we are using a product that is no safer for the environment and paying a premium for it.

Will they ever get lead out of PCBs? Probably depends on whose report the government officials read. There are a lot of alternatives available already so I'll worry about it if and when it happens.

IPC President Visits Capitol Hill On Behalf Of Small Businesses

Denny McGuirk, IPC president, recently testified before the House of Representatives Small Business Committee Government Reform and Oversight Subcommittee on "The Lead Toxic Release Inventory (TRI) Rule: Costs, Compliance and Science."

The hearing took place June 13, 2002, and, in addition to McGuirk, included the following witnesses: Kim T. Nelson, assistant administrator for Environmental Information, U.S. Environmental Protection Agency (EPA); James Mallory, executive director, National Non-Ferrous Founders' Society; Nancy Klinefelter, president, Baltimore Glassware Decorators, Representing Society of Glass and Ceramic Decorators; and Hugh Morrow, president, North American Office, International Cadmium Association. The subcommittee consisted of Committee Chairman and Congressman Mike Pence (R-Ind.) and Ranking Member Robert Brady (D-Penn.).


IPC president, Denny McGuirk, testifies before the House of Representatives Small Business Committee Government Reform and Oversight Subcommittee on "The Lead Toxic Release Inventory (TRI) Rule: Costs, Compliance and Science."
In his testimony, McGuirk voiced industry concern over the EPA’s lowering of the reporting threshold for lead and lead compounds from 25,000 to 100 lbs., under the TRI rule, and its decision not to convene an Advocacy Review Panel as required under the Small Business Regulatory Enforcement and Fairness Act.

"IPC members, along with many other industries, are concerned that the burden of this rule upon business has been significantly underestimated," said McGuirk. "To make matters worse, EPA has failed to provide effective compliance assistance, thereby further increasing the burden on those least able to bear it.

"Last month…EPA acknowledged that there had been problems with the implementation [of the rule], but noted that the first year of a regulation always serves as a ‘road-test.’ That may be EPA’s perspective on the problem, but it is not shared by the thousands of small businesses that will become the accident victims as EPA takes its ‘test drive.’ Moreover, such a cavalier disregard of major problems identified by small business suggests they are at the risk of becoming the road-kill of EPA’s road test."

In his conclusion, McGuirk requested that EPA suspend or delay their lowered reporting thresholds for lead until small business concerns could be addressed properly and the results of EPA’s Science Advisory Board’s review could be completed and assessed.

Also during the hearing, Representative Pence questioned Assistant Administrator Nelson about the scientific community’s support for the rule, voicing his concern that it represented a misallocation of EPA’s resources and would put a great burden on small businesses.

IPC advises its members to prepare for compliance with the July 1st reporting deadline, but encourages small businesses to hold their filings until June 30, 2002.

The witnesses’ complete testimony can be viewed at www.house.gov/smbiz/hearings/107th/2002/020613/index.html.

Implementation of Lead-Free Solder
Thursday, November 14, 2002
10:00 am - 12:00 pm Central Standard Time


Developments in Europe and Asia are dramatically impacting the use of lead-free solder. Did you know, in Europe for example, it now appears any goods put on the market (for sale) after January 2006 must be lead-free regardless of when it was manufactured? Or that major OEMs in Japan, like Sony and Hitachi, are producing lead-free products?


Regardless of where you are in the electronics industry supply chain, you need to understand not only the environment (both legislative and customer driven), which more than likely will drive your company to use lead-free solder but the types of the lead-free solder available.

By David Manners, Electronics Weekly -- Electronic News, 2/26/2003

MONTEREY, Calif. -- U.S. companies are beginning to wake up to the lead-free electronics production movement, which was pioneered in Japan and taken up by European manufacturers.

“We’ve just started to get enquiries from US customers about lead-free products,” Julian Psaila, manager of MIPS processors at PMC-Sierra Inc., told the Globalpress Leading the Recovery conference this week.

According to Psaila, until recently, there was little interest in lead-free components in the U.S.

"A few of our printer manufacture customers are now asking about it, probably because they want to ship products to Europe and products containing lead may be banned from the European market,” Psaila said.

PMC-Sierra is already shipping some of its MIPS processors in lead-free packages and plans more.

“The lead-free movement started in Japan -- not as a legislative thing but as a voluntary movement probably to help consumer marketing,” Psaila said. “In Europe it’s more of an EC-driven thing to have lead-free products by 2006.”

Only this month Texas Instruments Inc. announced its intention to go entirely lead-free for its logic products.

Vitronics Soltec invites North America Electronics Manufacturers to the "Make the Right Connection in Lead-Free Soldering"
18-City LEAD FREE SEMINARS TOUR

Meet the Challenges of the New Reality

In these tough times of tighter budgets and shrinking margins, you must remain profitable to survive. Increasing process efficiency as well as increasing yields by cutting defects and overall costs can widen narrow profit margins. That's why Vitronics Soltec announces the North American Advanced PCB Assembly Technology Tour, with this year's theme "Make the Right Connection in Lead Free Soldering".

Building upon our research and customer experiences, this year's program will illustrate the 5-Step Method to achieve an efficient Lead Free soldering process. Included will be the impact various soldering technologies have on cost, process control, yield, and experiences of those assembling with Lead Free technologies.


Today's Critical Market Trends

Where is the Market going? The electronics industry is witnessing a revolution in the business practices of OEM's, CMS's, Device Manufacturers, IC packagers, Material Suppliers, and Process Equipment Manufacturers. It's a tough environment and one to which we must adapt. In this seminar we will examine how the electronics world is redefining itself. We will provide you with the latest development in technology and manufacturing, including Lead Free mandates, the momentum for ISO 9001 and 14001 certification, and the impact of China.


Lead Free Implementation – 5 Steps and Case Studies

There are many Japanese manufacturers currently producing Lead Free electronic products with the prospect of gaining market share. In Europe, implementation of the WEEE and RoHS directives by June 30, 2006 in the EU will mark the end of the eutectic tin-lead era for most electronic applications.

For the North American assembly market, those companies with interests both domestically and globally will need to follow suit in adopting a Lead Free process. Successful implementation of Lead Free soldering requires careful, well thought-out planning and rigorous process monitoring to ensure quality and to keep the process in control. It demands a comprehensive process definition, proper material selection, and methodical ongoing review and analysis.

Our 5 Steps to Successful Lead-Free Soldering – reflow, wave, and selective- illustrates how to achieve a robust, repeatable Lead Free soldering process that will deliver consistent high yields. You will learn from the real life experiences of others with actual process data and case histories. Discussions will include the impact of legislation, standards, compatibility of materials, and the increased need for standard SPC measurements for all types of soldering processes.


Selective Soldering: Get The Most Out Of This Powerful New Process

Best described as an "Enabling Technology", Selective Soldering is highly capable and flexible. The seminar will review every aspect of the process, from fluxing and preheating to Selectwave versus Multiwave solder wave types. And we will show you how to best use these two different approaches – separately or together – to achieve optimum results in high mix production.

Then, we'll start you thinking "outside the machine" and discuss how total web integration and control adds a greater dimension to the machine and the process. Actual application data and process parameters will be discussed.


Optimize Your Reflow Process

The Lead Free reflow process window is tighter compared to the soldering process window of tin lead assemblies. Achieving a reflow process that does not exceed the maximum peak temperature rating of the various materials BUT also achieves the minimum peak temperature necessary to form that reliable joint is critical. Simultaneously, other reflow process parameters such as the Preheat Condition, Time Above Liquidous, and Cooling Conditions are equally essential in delivering a high yield electronic product.

The seminar will help you keep your reflow process optimized, in-control, and flexible enough to keep an open "process window" in the face of these future challenges. We'll look at lead-free process considerations including temperature, dT, throughput, footprint, cooling rates, nitrogen usage, and other important process variables.


Cost-Effective Lead-Free Wave Soldering

Wave soldering with lead-free alloys continues to advance! Several major electronic assembly houses are currently in mass production with Lead Free solders. We will assist you in identifying and understanding critical process problems including: poor yield, fillet lifting, decreased wetting, costly dross, and the leaching of metals into the solder pot. Again, we will use real-life solutions already implemented by other assemblers. And we will teach you how to apply SPC tools and analysis to optimize and maintain your production.


Question & Answer Session

After the seminar, join us for a lively question and answer session.

Narrow profit margins are a fact of life in the industry today. Building a more efficient soldering process and utilizing less-costly procedures, cutting waste, and reducing defects will boost profitability. We'll show you how.

Tom I am surprised at the theory you propose that lead solder in printed circuit boards does not hurt the enviroment, bull as some of the boards end up in a land fill some time after there usable life, they will be subjet to leaching the lead salts into the water flowing though the land site, even with trying to collect the water and treat it. To all the boards that end up along our roads or in small dumps they definnetly do pose a threat. The lead content does have an effect on hot air operators and solder assembliers. and no matter what the IPC says its time to get the lead out. and PS gasoline definitly did have some tetra lead in it till the early 90's when it was replaced with what some are saying a worse subsetute. Phospate. I converted my PCB facility to a plated pladdilm in the 90's and it worked well, untill the supplyer stopped producing it.

Robert,

I agree with you. Just to set the record straight, it is the IPC organization that did the environmental impact studies and summarized that it was minimal.

I personally would like to see all Lead Products eliminated.

The replacement of hot air solder leveling (HASL) has been an area of concern for the PC board industry, which wants to reduce thermal shock to the board during HASL processing and to provide a flatter and more uniform finish for fine-pitch assembly.

Options for lead-free surface finishes, compatible with components and circuit boards, include organic solderability preservative (OSP), nickel/gold, palladium, electroless palladium/electroless nickel, palladium/gold, nickel/palladium/ gold, tin, silver, lead-free HASL tin/copper, immersion silver, immersion gold/electro less nickel and tin/bismuth.

Many studies of lead-free solders have examined either freshly cleaned copper or copper with OSP. The Printed Wiring Board Manufacturing Technology Center (PWBMTC) is conducting a study of board finishes for lead-free solders.

Another issue, that of PC board compatibility with high soldering temperatures, requires the use of high-temperature laminates, which are more expensive. In this context, low-temperature lead-free solders may be an option."
http://www.chipscalereview.com/issues/0300/solder15.html

"Soldering Temperatures
Lead-free high tin alloys require higher processing temperatures in both wave (approx. +10°C) and reflow (+20-25°C), which could damage components' plastic packages, cause board warping and problems with the solderable finish. Traditional SnPb HASL finish boards can be replaced by suitable alternatives, including SnAgCu HASL, NiAu immersion, tin or silver coating (e.g. FST® or Alpha Level®) and organic solderability preservatives (e.g. Entek®). Equipment concerns such as working for extended periods at higher temperatures should also be considered."
http://www.alphametals.com/lead_free/

"Teledyne Halco Dedicated to developing and implementing a lead-free HASL process that is compatible with PCB manufacturing and assembly standards by January 2001."
http://www.leadfree.org/USMarketPerspectives.htm

"Lead-Free Hot Air Solder Level (HASL)
Even though lead-free HASL is available for PWBs, some manufacturers may choose to move away from this process if required to produce lead-free product.

If chosen, alternative HASL finishes will most likely work well with most alternative alloys and will wet faster than plated finishes or coatings. Concerns with this finish include warpage due to higher processing temperatures and PWB absorbed process chemistries, although they can sometimes be removed with cleaning."

IPC and JEDEC bring you the Fourth International Conference on Lead Free Electronic Assemblies

October 21 Education Courses October 22-23, 2003 Technical Conference

Frankfurt, Germany

IPC - Association Connecting Electronics Industries and JEDEC - the Solid State Technology Association are sponsoring the 4th International Conference on Lead Free Electronic Assemblies from October 21-23, 2003 in Frankfurt, Germany (Hotel to be confirmed) Messrs. Martin Freedman, Molex, and David Bergman, IPC, are the Conference Chairs.

The European Union has drawn the line in the sand. 1 July 2006 is the date that the Directive on the Restriction of Hazardous Substances in Electrical and Electronic Equipment will require the majority of electronic products sold in Europe to be lead free. Global public and political pressure against lead continues to grow. International OEMs are becoming more sensitive to the issue and continue to press their suppliers to develop phase-out plans. A ban in Europe will have an effect in the global marketplace, forcing all manufacturers to eliminate lead as effectively as a local ban. Manufacturers in all regions, including Asia, will need to prepare for this change. Companies not directly affected by the legislation, in exempted markets, still need to be monitoring this issue to assess the effects of changes in the supply chain and customer demand.

Data keeps coming in from individual companies’ and consortia efforts. Many challenges still exist and the path forward to success is not one of consensus. Companies need to stay aware of the hot issues in order to focus efforts that will allow success to be achieved by 2006.

Papers are sought in all areas, including:


· Component issues (moisture sensitivity, BGAs, obsolescence, etc.)

· Design issues (for ease of production and disassembly)

· Material availability and toxicity issues

· PCB issues (effects of lead free process temperatures, board finishes, etc.)

· OEM/Consumer demands/voluntary elimination dates

· Recycling options (examples, plans and concerns)

· Business issues (supply chains, cost – benefit analysis, etc.)

· Reliability evaluations (temperature cycling data, tin whiskers evaluations)

· Finishes issues (organic solder protectants, immersion tin, silver, electroless nickel, palladium, etc.)

· Alternative assembly processes that may facilitate lead free implementation.
