Marking and Labeling: |
|
Alliance has a Pb-free labeling method for the
packaging of all Pb-free products. The lowest level shipping container
shall identify the products as Pb-free. |
|
|
|
Qualification: |
|
Alliance Pb-free packages comply with the most
current JEDEC JSTD-020 standard for peak reflow temperature (260°C for
small packages, 250 C for medium size packages, and 245°C for large size
packages. Size is defined in JEDEC J-STD-020). |
|
Reliability tests include Temperature Cycle,
Autoclave and Temperature/Humidity
under the standard test conditions. Additionally, Alliance works with
suppliers and partners to perform tin whisker, and solderability tests.
Data for these tests are available upon request. Reliability tests for
some packages are under progress |

Material Sets: |
|
By collaborating with our suppliers, Alliance
sources the best material sets for lead free applications. The material
sets must be reliable, environmentally friendly, and robust to meet the
requirement of higher reflow temperature (up to 260°C max.). The mold
compound that Alliance uses for lead free packaging are free of Brominated
Flame retardants. Additionally, Alliance
Pb-free packages comply with the RoHS Directive and do not contain
any of the following materials: Lead, Mercury, Cadmium, Hexavalent
Chromium, and the PBDE and PBB flame retardants. For the solder
finish/material, the lead free packages have pure matte tin plating finish
or Sn-Bi plating. These materials are industry preferred materials and are
chosen due to their availability, lower cost, and reliability. |
|
|
|
Readiness to supply lead free parts: |
|
Alliance has already qualified most packages for
the lead free process and will complete qualification of all existing
packages for lead free process by Q1 2005. |
|
Lead free samples are available upon request for
all existing products. |
