What is the best preservation condition for
keeping the RoHS compliant product?
The preservation environment must be controlled to prevent any caustic substance/effect
(including airborne) or dew condensation. The expected ambient temperature
should be between 5 and 40° C and relative humidity of 20 to 70%.
Are there any differences between Lead Free
products and RoHS compliant products?
Previously listed "lead free" products were studied and considered
compliant, in regards to lead content only for lead-free soldering of terminal
connection, case, and hoop. At that time, Cadmium, Mercury, Hexavalent chromium,
PBB, and PBDE were not studied. So we can not say "lead free = RoHS
compliance". In fact, only a few products reviewed their constituents
on the six hazardous substances and eliminate them. We posted the list of
the converted and existing (RoHS) complaint part types and Spec No. on Sumida’s
website.
When is the expected date of full conversion
of Sumida products to RoHS compliant products?
After January, 2006, Sumida basically only manufacture RoHS compliant products.
NOTE: Regarding customized products, we will follow the date of specific
customer requirements.
How can customer distinguish the RoHS compliant
devices from the non-compliant parts?
SUMIDA standard product (S-074-XXXX specification
sheets): A RoHS logo will be added on specification
and on the reels & boxes.
Customized products: We basically change the part
name in conversion from lead free to RoHS compliance.
Actually, we follow the customer’s requirement.
Can customer order those non-compliant RoHS
products?
Basically Sumida does not manufacture non-RoHS compliant standard products
(S-074-XXXX) after January, 2006. However, we will continue to manufacture
as customized products (to the original spec) if specific customers need
the non-RoHS compliant product(s).
What types of Hazard Substances might be
typically included in Sumida RoHS non-compliant products?
Lead compound is used for solder and wire coating in some products. Hexavalent
chromium is used for plating. Conversion to alternate material without hazardous
substance is possible.
