Our Status
(1) Status of Existing Products
The use of 6 hazardous substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (6+Cr), polybrominated biphenyls (PBB), polybrominated diphenyl ether (PBDE) is restricted by RoHS directive. The metal circular connectors of the above mentioned series made by DDK only contain hexavalent chromium (6+Cr) for chromate treatment as the anti-corrosion finish.
(2) Our Schedule
As a general situation the anti-corrosion finish of metal piece parts such as screws has been shifting to trivalent chromium in black. However, it is not feasible to cope with the parts of aluminium alloy and zinc die casting of our products by the same plating liquid as that for the screws. At present the treatment liquid manufacturers are developing the new plating treatment liquid and have been trying to start shifting to the new plating in summer, 2005. We estimate that we need around three (3) to five (5) months to change the finish to the new one because we have a wide range of products. Also please note that the plating will be colour black due to the characteristics of trivalent chromium treatment liquid.
We would like you to understand that it is possible that there will be the mixtures of old and new variants whilst moving to the new specification. |
