The question has been asked - is there evidence that Toyota has gone lead-free? I found this discussion on SMTNET that discusses the topic (we aren't the only ones debating this subject) http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=14597&#Message61142 Toyota developed their own lead free alloy http://sciencelinks.jp/j-east/article/200016/000020001600A0589899.php Quote" Several engineers are readying the Toyota recall press daily to see whether Toyota - an early adapter of lead-free solder - is the first casualty." unquote http://retroworks.blogspot.com/2010/02/leadfree-solder-rohs-rumors.html Quote "January 2001, we inaugurated our own company-wide lead free project, starting activities and efforts to eliminate lead thoroughly" unquote http://www.toyota-industries.com/csr/environment/product/erectoronic_02.html Transforming Compliance into a Competitive Strategy http://www.internetviz-newsletters.com/cincom/e_article000667816.cfm?x=, (http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=61176) Here's the details on their solder: "A highly reliable Sn-Ag-Bi-In-Cu lead-free solder alloy was developed by improving the melting property, the wettability and the mechanical property of the Sn-Ag solder alloy which has a high thermal fatigue resistance due to the addition of bismuth, indium and copper. The optimum alloy composition for the Sn matrix is 2.5-3.0mass%Ag, 3.0mass%Bi, 1.0mass%In and 0.2-0.5mass%Cu. The additional elemental bismuth contributed to the control of the solidus and liquidus temperatures and the improvement of the wettability and tensile strength. Indium contributed to the control of the solidus and liquidus temperatures and the improvement of wettability. Copper contributed to the improvement of the ductility which is degraded by the addition of bismuth. In comparison with the Sn-3.5Ag eutectic solder, this new lead-free solder alloy has a 19.DEG.C. lower solidus temperature, 6-7.DEG.C. lower liquidus temperature, 4% higher spreading factor and 200% higher tensile strength. Its elongation is equal to and above Sn-3.5Ag at 125.DEG.C. though it is half as long as that of Sn-3.5Ag at 25.DEG.C.. It was confirmed that this new lead-free solder joint has a high thermal fatigue resistance and the same electrochemical reliability in comparison with the conventional Sn-37Pb solder joint.

Of course, the components we all buy, are mostly lead-free tin plated. http://www.toyota-industries.com/csr/library/pdf2003/P18-25.pdf "Under the European Union's end-of-life vehicle (ELV) directive*, the use of lead, mercury, cadmium and hexavalent chromium will be banned from all vehicles sold in Europe starting from July 2003. In response to the ELV directive, Toyota Industries' Product Technology Subcommittee has established objectives aimed at reducing the company's reliance on substances of concern in all of its business activities including its non-vehicle related businesses. During FY 2002, Toyota Industries made changes to the design of parts that previously contained lead, cadmium or hexavalent chromium and switched to using alternative chemical substances. Toyota Industries also asked its suppliers to submit data regarding the inclusion and quantity of banned substances in materials and parts supplied to the company, and also requested that its suppliers submit plans for eventually phasing out the use of banned substances. In addition, Toyota Industries revised its in-house guidelines for substances of concern to reflect the policy of banning certain designated chemical substances." "Lead-Free Circuit Boards Lead contained in solder used in circuit boards has been noted for polluting the environment when it is not properly disposed of. Consequently, Toyota Industries is trying to switch to lead-free solder in its circuit boards for its industrial machinery, automobiles and textile machinery products. When designing circuit boards with lead-free solder, Toyota Industries had to overcome various issues such as the high melting point of lead-free solder, which made it difficult to control soldering temperatures while ensuring that parts could stand the heat. However, Toyota Industries was successful in overcoming these issues and in January 2003 began producing lead-free circuit boards for use in the displays for one of its electric reach truck models."
