Due to worldwide environmental concerns, the need for lead-free devices in electronic components and systems continues to receive significant attention within the semiconductor and electronics industries.
China RoHS is the official measure for pollution control in electronic products in China. China’s RoHS is similar to the European version of RoHS which regulates cadmium, lead, hexavalent chromium, mercury and two brominated flame retardants, Polybrominated biphenyls (PBB) and Polybrominated diphenyl ether (PBDE). Also similar to European RoHS, China RoHS has the same threshold of 0.1 percent for all substances listed above (except for Cd which has a 0.01 percent threshold) and contains a series of useful exemptions for certain important uses of lead.
All TI finished IC products labeled as "Pb-free" or "green" are fully RoHS compliant in China and Europe. The only substance that may be contained in TI finished IC products above the 1000 parts per million (ppm) threshold is lead (Pb). Any TI product containing lead (Pb) above 1000ppm will not have the Pb-free symbol on the TI product label.
TI products labeled without the "Pb-free" symbol contain one or more of the China RoHS materials above the allowed MCV. The relevant environmental information concerning Environmentally Friendly Use Period (EFUP) for these types of products is:
Currently there is no testing or industry standard to determine the EFUP under the China Marking for Control of Pollution Caused by Electronic Information Products Standard SJ/T11364-2006 (China RoHS). However, only lead (Pb) may be above the 1000 ppm MCV in certain designated finished IC products (BGA and leadframe devices).
