You might think that memory cards are gradually becoming less popular, but the truth is that the demand for memory cards has continued to grow along with the emergence of new handheld cameras and security cameras that record videos and photos in higher-definition formats. It is because of these new demands that will allow users to pay more attention to memory cards.

Potential Risks and Solutions

SD cards are currently the most used memory cards in the market. Based on customer complaints Allion has collected over the years working with our clients and well-known manufacturers, we found that the most common issue was that computers or systems could not read the SD card. According to our data, SD cards can have undershoot or overshoot issues during data transmission that produce crosstalk and interfere with the clock signal. This can allow the SD card to be unrecognizable to a computer or system, leading to customer complaints.

Allion has a complete range of testing equipment and decades of experience. In this situation, we used an oscilloscope to test the pins on the SD card and observed the waveforms during data transmission. If any issues are found, we can quickly report them to our client. Below is an example of actual test results of data signals and clock signals.
