Question:

Does Cypress use cyanide during the plating process?

Answer:

Cypress does not have any plating process; hence, cyanide is not used in the manufacturing plant.

For lead frames with NiPdAu finish: Cypress NiPdAu-finish lead frames are preplated. According to one of Cypress’s suppliers, cyanide is not possible to eliminate, because the plating is based on a cyanided bath in chemical and without it, it is not possible to plate the lead frame. Since it is only used for plating under a chemical bath, the finished lead-frame material is not affected.

For lead frames with pure Sn finish: Parts with Pure Sn-finish lead frames come from Cypress-selected subcontractor sites with their in-house plating process. Cyanide plating is not used in their plating process.
