Powtech 5w Frequency Inverter Case of Brake Resistor

The Powtech as the production of environmental protection and energy-saving products, high-tech environmental enterprises, from procurement of materials, to manufacturing , Concerning about every aspect of environmental protection is an important task for us . In about 2000 years ago, as the main component of lead solder metal bonding dissimilar materials began to be used , and today for industrial machinery , computers, mobile phones, digital cameras and other electronic products · Almost all electrical printed circuit bonding materials.However , has always been used as the main component of the solder Lead is a bad influence on the environment substances ( environmental load substances ) , so with environmental awareness , people requirement excludes the use of lead . July 2006 , the European implementation of WEEE & RoHS directive, the main component of the solder containing lead or sale of lead as the main ingredient used in the product that is not licensed in Europe . Therefore OAK Drive and global efforts to promote many manufacturers use lead-free solder , is committed to comply with WEEE & RoHS directives.
The Inverter of Powtech, manufactured using lead-free solder . This lead-free solder with Sn-Ag-Cu ( tin, silver, copper ) lines and Sn-Bi ( tin and bismuth ) is solder as a main component , but also add Ni (nickel ) and Ge ( germanium ) . With excellent adhesion and heat resistance and thus inhibit oxidation of dross ( tin oxide ) reduction of outstanding features.

Strict material selecting and rational combination

The materials of Powtech used in accordance with the principle of minimal environmental impact choice . Conform to disable lead, hexavalent chromium and other materials European Directive ROHS ( Restriction of Hazardous Substances ) .
