Pb-Free Packaging

The Cypress roadmap to lead-free packages demonstrates our commitment to provide leadership in lead-free packaging. Lead (Pb) as an alloying element in solders has resulted in environmental concerns due to potential toxicity. Therefore, various legislations to ban lead are being driven worldwide.

Cypress uses nickel-palladium-gold (NiPdAu) technology for the majority of leadframe-based packages. Long-term packaging roadmaps drive NiPdAu as the preferred solution for Pb-free packages.

A high-level review of the Cypress Pb-free position is available (see Cypress RoHS Packaging Compliance letter). Specific package information is also available. Package Material Declaration Datasheets (PMDDs) identify all substances contained within Cypress packages. PMDDs also confirm the absence of many banned substances. The information in the PMDDs will help Cypress customers plan for recycling or other "end of life" requirements. PMDDs are available by selecting the Package Family, then Information Type (choose Package Materials Declaration) in the top right Packaging Information portlet.
