Since your products are RoHS compliant, can I assume that they are Lead Free (Pb free)?
RoHS restricts the use of six hazardous materials. One of the restricted materials is Pb (Lead). Lead-free is often used (or misused) to describe RoHS compliant products. However, RoHS compliant products are not completely Pb free as impurities up to 1000ppm (0.1%) are permitted and there is an exemption allowing the use of lead in high melting point solders required for SMD converters (a suitable lead-free high melting point solder did not exist when the regulations were drafted). A revision of the RoHS regulations is planned in 2010, when it is expected that many of the exemptions will be removed.
