Technical Success Story: Solving SD Card Customization Issues

 

Background: A frequent Delkin SD card customer needed to expand the use and data output of their application. When testing content loading equipment, or duplicators, they discovered that their SD cards were failing when the duplicators added data. Because they had orders coming in, they needed to quickly find a solution to the problem.

 

Customer Story: After purchasing new duplicator equipment, the OEM experienced a series of failures in their SD cards when loading data. The SD cards ran fine with the old equipment, but the new duplicators triggered a high rate of failures. The OEM had already purchased the duplicator equipment, so they had to find a way to make it work. Delkin’s Customer Applications Team stepped in and helped the application manager find a solution.

 

Delkin Discovery: The customer checked with the duplicator manufacturer to ensure there were no compatibility issues. The manufacturer discovered that the error was occurring during the read verification test, instead of the copying phase. They then issued a report saying that the cards were not compatible with the duplicator.

 

The customer shared the results with Delkin, and the Customer Applications Team started to investigate. They reproduced the arrangement the customer was using, and their results were in agreement that the problem was occurring in the read verification test step. At the same time, the team analyzed the operations of the old duplicator that worked to learn more about the system.

 

Delkin Solution: Delkin discovered that the signal integrity was meeting the right timing specifications and that the power draw and other features were in the correct range. However, the Delkin SD card featured a slightly reduced BUS strength—a feature Delkin offers during the initialization of SD cards in order to save power. Delkin’s team also realized that the cable of the new duplicator was twice the length of the one in the old system. Combined with the reduced BUS signal, the longer cable caused card signals to weaken. The cord could not be reduced, but Delkin was able to increase BUS strength for the customer.

 

Lesson Learned: Most Delkin customers prefer SD cards optimized for power, but in this case, the feature caused a problem to develop after a new host was introduced. Though the duplicator manufacturer could not perform a customization, Delkin was able to provide a simple fix with customized SD cards with new initialization instructions, ensuring the failures were prevented and the customer could move forward.
