Our industry is making one of its most challenging and evolutionary steps in going from SnPb to Pb free products. The issues are many and they must be well understood to avoid costly mistakes or misspoken statements. In this online course you will learn the most critical pieces about the transition to lead free. It is the most extensive and broadest coverage of this topic available anywhere. The transition to lead free first starts with understanding the directives and global trends. Then learn about the possible alloy replacements, their pros and cons along with the environmental considerations and reliability; each backed up with testing and data. The PWB finishes are dealt with in detail covering a wide range of optional finishes. That is followed by what the effects are of intermixing different board finishes, PWB plating types and solder alloys: addressing both forward and backward compatibility. Next, another important topic, tin whiskers are explained in a detail not seen anywhere else. Now you are only half way through! The next section gets into failure modes such as CAF, causes and solving tombstoning and voids, lead free printing issues, lead free reflow profiles (old compared to new recommendations) and how they relate to a variety of defects during reflow that can be solved by making slight changes. Learn what Motorola gained from extensive testing such as drop tests. Finally one more very important topic is covered, wave soldering. It covers topics such as tin pest, tin corrosion, fluxing, setup and the optional pin in paste process. Authors Dr. Ronald C.

Module 1: Lead Free Initiatives and Global TrendsThe electronics industry has been mandated to convert to lead free products per two directives: WEEE and RoHS. How these changes are coming about and how the segments of the world are dealing with this are presented along with graphs showing the status.
Module 2: Lead Free Alloy SelectionThe selection of a replacement for SnPb is at the heart of the issues confronting many in transitioning to lead free. The alloy options being considered by most, their cost implications, SAC alloys choices and what the industry are mainly favoring are presented.
Module 3: Is Lead Free a Good Thing?Changing to lead free has environmental considerations, so why are we targeting eliminating Pb anyhow? So of the lead free alloy choices what makes the most sense is covered.
Module 4: Lead Free Alloy ReliabilityThe change to another alloy from SnPb means we have to address the reliability of any possible choice. Thermal testing has been performed on many such choices and is presented as well as mechanical testing and out of plane bending.
Module 5: Lead Free ComponentsUsing lead free components with SnPb and vice versa is of concern and can cause problems, so understanding forward and backward compatibility are necessary pieces to the lead free transition puzzle. Learn how tin whiskers are created and on what surfaces along with what it takes to prevent them. It is vital for components the labels need to tell us which are SnPb and which are Pb-free.
Module 6: Lead Free Surface FinishThere are many choices when it comes to PWB finishes. Some choices are much better than others. In this section this is presented showing the pros and cons of each along with a summary table comparing them all.
Module 7: Failure ModesThe alloy changes in going to Pb-free cause old problems to reappear but for new reasons. Tombstoning and voids are the recurrent defects that can be controlled once you understand the causes, which is detailed in this section.
Module 8: ImplementationImplementing Pb-free and how the industry stands is an issue. ELFNET did a survey to show where companies stand and it is eye opening to see how much work has yet to be completed by many. To assist those in need an assessment tool is included to rate where your company is in the changeover process.
Module 9: Lead Free Printing and PlacementPrinting lead free paste creates new challenges. The quality of the print, paste selection, response to pause, viscosity considerations, tackiness, stencil life, shear thinning, solder balling and stencil design are each covered in this section. The changes are subtle but the effects are major.
Module 10: Lead Free ReflowChanges are required in the reflow profiles to achieve optimum results when changing to different alloys replacing SnPb. The affects of the profile on 8 different common defects is presented so you may learn the cause and solution for each. Also included is a recap of the results Motorola found during their extensive analysis.
Module 11: Lead Free Reliability IssuesThere are important reliability considerations when evaluating different alloys to replace SnPb. Data is presented from Motorola which did extensive testing for reliability using a test vehicle to evaluate mechanical and thermal shock.
Module 12: Lead Free Wave Soldering & Alternative Soldering MethodsThe effects of changing alloys on the wave soldering process are significant. It affects both the equipment and the process. The results are the effects of tin pesting and corrosion. So what is the industry switching to? That plus fluxing, setup and dwell time is explained to complete the transition.

As a solution for large volume users of this course we offer several plans that may be of interest to you. These solutions are designed for corporations and universities. A minimum number of students is required to make these solutions cost effective. Sub-Domain: Making access and use of courses fast and easy is paramount. By having us setup a sub-domain it makes it very easy to get your training program underway. When a company needs to train 100 or more people for a curriculum we offer to setup a sub-domain on our server at no extra charge. The advantages to this offer are numerous. We do the work and will even setup the student files so the student simply logs onto the Internet, uses an assigned UserID and Password and has the content available for learning or reference use right at their fingertips. Students may log in and out whenever they want. Access is based on a term, with 1 year the norm. Each student file is kept confidential. Another key advantage is with the sub-domain we make available to the client the ability to edit the courses they have licensed. They may opt to remove certain content or add new content themselves from their computer as html, pdf, or swf files. The edit course software is fast and easy to use with no programming skills required. By customizing the course the content can be made to fit your company's exact needs. If you need an extra hand we are available to assist. Corporate Server: The fastest access of content is over a corporate Intranet. It also could be you would like to add content that you feel is proprietary and want the highest level of security possible, then licensing courses and software to run on your corporate server makes a lot of sense. Each course may be licensed or purchased, as well we offer licenses for our edit course feature within our TechEdge Web-Based engine for corporate users to edit licensed courses and to develop new ones yourself using programs like Microsoft Word, PowerPoint, or Flash. It is simple, fast and easy. Here's the typical server requirement for a 50 concurrent user hosted connection: NT 4/2000 Server 500mhz p2/p3/amd athlon 256 RAM (512 recommended) IIS, PWS or compatable web server software SQL or Access 2000 ODBC compliant database driver Coldfusion Aplication Server 4.0 or higher [ click here ] for more info on coldfusion Course Development: There are many who would like to put content up on the Internet or on Corporate Intranets but either do not have the knowledge or the time to do it. To help we can offer onsite training, tools, and experience on how to do it in conjunction with licensing our software and courses. If you have a need for a course to be developed we also have that capability, demonstrated by the quality of the courses you see we offer, which are all made by our staff. More Information: If you are interested in any of the above multi-user solutions for this course, please contact us for more information and a quotation. You will be pleasantly surprised at how affordable these multi-user solutions really are! | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
