Custom bare die up-screening
Your vision is our mission. Central excels at listening to customers’ challenges and designing custom solutions that other manufacturers have no interest in pursuing.
At times, customers do not require full MIL equivalent testing, and instead provide Central with specific testing requirements. For other applications, a customer may require even more intensive testing than MIL equivalent. Central excels at designing a customer-specific solution to support the full array of design requirements that our customers may specify.
Customer SCDs can be stored confidentially with Central to ensure that future products adhere to the same testing. Customers can update SCDs at any time. To ensure further design security, custom devices are given unique CEN part numbers; these part numbers are not used for any other customers or devices.
