Pb Free Products | 22 September, 1999

I am attemping to gather as much information on the issues with and progress in solutions for manufacturing Pb free products in response to European initiatives (WEEE). I am intereested in component issues with As Made lead terminations (no Sn/Pb) as well as information comparing solder pastes and process set-up. Any detailed information would be appreciated.

All you need to do is go into the literature of the last 40 years and look at the number of papers. There has been some excellent work done in some of the labs of the major OEMs, Bell Labs, IBM, Motorola, Ericsson, HP, etc. The problem is with all the down-sizing and other bean-counter changes, these laboratories are shadows of their former selves (is they still exist at all). Therefore, the resources that were brought to bear onto the Sn-Pb solder reliability issue, simply do not exist for application to the lead-free solders.

The copy of the latest WEEE draft that is now on the ICER web site, is a draft for the 3rd draft. This is a leaked copy, which should be an internal EU commission document, and as such not in the public domain. However, I understand it is now in wide circulation, as evidenced by the ICER web site and others.

Attendees of the International Summit on Lead-Free Electronics Assemblies received a copy of the Department of Trade and Industry (DTI) report, "Lead-Free Soldering: An Analysis of the Current Status of Lead-Free Soldering" with their conference proceedings. This detailed report will be most useful in the development of the IPC roadmap on lead-free electronics assemblies. The paper is available on www.lead-free.org

Back in August 1999, Hadco offered to coat your bare copper test panels with Sn3.5Ag "using our dedicated HAL line. We request the panels to be an minimum of 12 inches in one direction, but no more than 28. We respectfully request that you supply between 2 and 30 samples. Please note that the panels must be bare copper. Reworks or alternative finishes can not be processed. After 30 days, another lead-free alloy will be put on-line and the offer will be repeated with the new alloy. We welcome your feedback on what alloy to evaluate each time. There is no charge for the service, and we ask that samples be sent to: TET Halco, 8 Delta Drive, Londonderry NH 03053, Attention: Sherry Goodell, (603) 437-8653, Fax: (603) 434-4156, sgoodell@mediaone.net or sgoodell@teledyne.com"

"I could forward you some chip inductors that have a gold plating over nickel. They would be rejects and not available on T/R. Physical size of the parts is 0.100 x 0.100 inches. These could be mounted on a 1008 chip land pattern geometry. How many do you need and where should I forward them?" Bill Grajek, API Delevan, Inc.

"TI can supply both through-hole and surface mount components with a Pb-free finish to anyone performing evaluations. Texas Instruments is nearly 100% converted in our Logic and Linear product groups to Ni/Pd finish which is Pb-free. We've been shipping totally Pb-free components since 1989 and a rough estimate is at least 30 billion Ni/Pd finished ICs in the field. This is not meant to be a plug as this site is not intended for commercialization or marketing, but we would like you to know that we can supply dummy components or daisy-chain units, whichever you prefer. You can contact me directly with details of your request. We would be very interested in the results of any work that you do.

Check: http://www.ti.com/sc/docs/products/logic/package/palladm/index.htm

In the near future we will have a simple route available on our web page for anyone requesting evaluation samples." Doug Romm, doug@ti.com

"Motorola SPS should be in a position to release 8/14/16 pin SOICs with a palladium finish for trials. I have tried to find the original PCN notification for reference, if I find it I will forward. If you have any problems with your local outlet I will forward contact details." Martin Bund Procurement Engineer Motorola Ltd, +44 (0)1793 568940, Fax +44 (0)1793 568722

"You can find "dummy" CBGA and LBGA from Topline with Sn96Ag4 balls." sales@toplinedummy.com

Various solder suppliers (eg, AIM Castin, Kester, Cookson Fry Technology) provide lead free materials.

Look at electroless nickel over gold, immersion tin (eg, Omikron, Dexter), which are no-lead.

Your project is worthy, I�ve gotten you started. Now, you need to keep us up to speed on you findings.

Who could I phone, who could I ask? Just to learn that this wasn�t a problem at all for others Sometimes the best solution for particular problems came weeks, month, years later at shows, talks with others. With the internet I thought it might be useful to have a forum where everybody could join and contribute to some problems others have and get some tips myself the quick way. So, to implement things, decide,try and experience how things apply for me and my special problem is still in my own responsibility. I found this forum and that�s what I thought it should look like, and the problems are the same everywhere and that�s where all the people are, everywhere but only about 20Inch and a bit of hacking away.

The only problem with the being shot progam is it often isn't fatal. Been shot many times myself, but seem unable to transend the threshold - marriage or the everafter. Still, if you persist, when I come back I'll buy your services. Never know when a sentence might need some friendly modification.
