Material Safety Data Sheet
This MSDS covers the Copper Based and Ferrous Based Leadframes supplied by Jade Precision
Engineering.
Jade Precision Engineering鈥檚 Leadframes are non-hazardous in their as-shipped form.
Under normal processing or assembly hazardous dust or fumes are unlikely to be generated.
However, incorrect handling of the product or production scrap may lead to injuries. Operation such
as trimming may create hazards to eyes or skin from flying particles of the said operation.

Skin contact Health hazard is not expected to occur. May
cause allergic reactions in some individuals

Carcinogenic effect: Not known.




Rev. 5
Section IV: Emergency and First Aid Procedures

Inhalation: Remove victim to fresh air and call doctor
