— What has AOS done to meet RoHS requirements?
Starting in August 2004, we began converting our products to RoHS compliance
and achieved RoHS compliance conversion in July 2005. We continue to follow
the RoHS update/amendments, to search/assess alternative materials for our
customers' further “Green” products.
The RoHS compliance declaration is available:
» Environmental Compliance Statement (PDF)
— Does AOS have any plan in place to remove the RoHS exemption application?
We applied RoHS exemption 7(a): “Lead in high melting temperature type solders
(i.e. lead-based alloys containing 85% by weight or more lead” in some power
management devices, used as 1st level internal connection (Die bonding, Clip bonding),
to achieve unique properties, such as the high melting point and thermal conductivity.
The brief of exemption application explanation is available:

REACH Regulation (Registration, Evaluation,
Authorization and Restriction of Chemicals)
— What is the requirement of REACH regulation?
REACH is a regulation of the European Union, which is adopted to improve the
protection of human health and the environment from the risks posed by chemicals.
In principle, REACH applies to all chemical substances, not only those used
in industrial processes but also in our day-to-day lives.
REACH managed the chemicals by the ways of Registration, Evaluation, Authorization,
and Restriction with specific conditions of Article, Preparation, and Substance
put on the EU market.
— What has AOS done to meet the REACH requirement?
AOS products are articles defined in REACH and do not release substances under
their regular use. Suppliers of the article should provide recipients with information
on SVHC candidates if products present above a concentration limit of 0.1% on an
article level. In addition, AOS products are required to meet REACH Annex XVII
requirement (restricted substance under specific application).
We have reviewed our products’ BOM and obtained information from our supply chain
along with SVHC candidates’ certificate. As a result, REACH declaration is available
at:

Green Product (Halogen Free/Low Halogen)
— What is the requirement of Green?
More and more downstream users have required to low halogen/halogen free products,
and industrial associates published the industrial standards for low halogen/halogen
free definition, such as IEC 61249-2-21, JS-709, IPC 4101B, and JPCA-ES01. AOS defined
Green (Halogen free/Low Halogen) below.
Substance |
Limitation on homogenous material level |
Applied scope and typical purpose |
Bromine |
< 900 ppm |
Resin, Rubber, organic materials, used as flame retardant |
Chlorine |
< 900 ppm |
Total Bromine and Chlorine |
< 1500 ppm |
Antimony |
< 900 ppm |
— What has AOS done to become a greener Company?
In 2010, all of our packages were converted to Green packages. Larger packages remain
non-halogen free versions, depending on customers’ demand.
Adding the suffix “L” to part numbers is used to distinguish Green devices from
non-halogen free devices. For example, AOT10N60L is a green version device, and
AOT10N60 is a non-halogen free device.
