Semiconductor firms unite in lead-free initiative

Posted : 08 Jun 2004

Freescale Semiconductor Inc., a subsidiary of Motorola Inc., has joined STMicroelectronics, Infineon Technologies AG and Philips Semiconductor to further promote a lead-free electronics packaging industry. Formerly E3, the group is now called E4 (environmental 4) and focuses on accelerating the use of lead-free packages while stimulating further development of environmentally friendly package technologies.

In July 2001, Philips, STMicro and Infineon Technologies teamed up to develop standards for lead-free products. The definition includes factors such as solderability, reliability of alternative materials and characterization of the moisture sensitivity level. Lead-free, as defined by the companies, is content less than 1000 parts per million lead by weight.

The E4 aims to provide a high quality drop-in solution for lead-free applications to all customers and members. Member companies will share databases and methodologies, collaborate on standards and develop a common conversion strategy for the transition to lead-free. This will promote a smooth introduction of new environmentally friendly semiconductor products.
