As a result of global concerns about the health of our environment and the impact of chemicals and pollutants on our air and water, the use of some substances have been restricted in electrical and electronic products.
Among other governments (US and Japan), the European Union Council of Ministers has adopted the RoHs Directive 2002/95/EC (Restriction on the Use of Certain Hazardous Substances in Electrical and Electronical Equipment). This RoHS directive, which came into effect on July 1, 2006, bans the use of certain materials, such as lead, mercury and cadmium in electronic products sold in the European Community.
OKI meets this RoHS directive for all Lead-Free (pb-free) devices. To fully comply with this mandatory requirement, OKI provides Lead-Free finishes for all devices and they are clearly marked for identification.
As Lead-Free coatings generally require a higher reflow temperature in the assembly process than traditional tin-lead compounds, the temperature characteristics of the assembly process have to be modified and require special attention. See the specification below.

Consequently we strictly recommend verification and approval tests before starting any mass production. Samples for testing are available for each part of our product range. Please note, an inadequate soldering process may cause problems and might affect the quality and reliability of the end product. We hope our information helps to smoothly switch to our Lead-Free products. For any question or more detailed information, you are always welcome to contact us.
