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.
