Range of services offered by CDA - special features

Aging test

The SD card products can be subjected to an aging test.

Analysis tools

A number of analysis tools are deployed, for example, to carry out long-run testing with the SD cards.

Procurement of flash storage media

We not only offer a wide range of storage media but also sound advice on which card is best suited to your needs.

Data duplication

CDA creates a master image from the data provided and, using its own copiers, copies it to the storage media supported by us (SD, SDHC, microSD, microSDHC) in no time.

ESD protection zone

Your flash memory products are produced in an ESD protection zone in accordance with IEC 61340-5-1.

This ensures that the storage media suffers no damage during production, for example through electrostatic discharges.

Fixed BOM

For production, CDA uses products with a fixed BOM (English: bill of materials).
If a BOM changes, the customers are notified through a PCN (Product Change Notification) beforehand.

Copy protection

Any SD card can be provided with special protection features as early as the production phase. By means of a process called serialisation, the card is allocated a file with encrypted data that serves as a serial number.

Since each SD card has a unique serial number, SD cards can be personalised automatically.

Suitable SD card applications can read the SD cards’ serial number and compare it with the encrypted data on the SD card.

In this way, it can be determined whether the SD card is an original or an illegal copy. We will be pleased to advice you when creating the corresponding security programmes.

Temporary or permanent write protection

Temporary or a permanent write protection can be set when writing (flashing) the SD cards. Our copiers can create these two types of write protection in a protected register. In contrast to permanent write protection, temporary write protection can removed by us at a later date, for example if the content of an SD card changes.
