Inkless Die Pick Map (DPM) Format
Cypress ships inkless wafers to customers with an accompa-
nying die pick map, which is used to determine the good die for
assembly and programming. Customers can also access
individual
DPM
files
at
their
convenience
through
ftp.cypress.com with a valid user account login and password.
Contact your local Cypress Field Application Engineer (FAE) or
sales representative for a customer FTP account. The DPM files
are named using the fab lot number and wafer number scribed
on the wafer. The DPM files are transferred to the customer’s
FTP account when the factory ships out the wafers against their
purchase order (PO).
