Description

Device for data recovery from USB memory}

The present invention relates to a data recovery device for USB memory, and more specifically, to a device that allows recovery of data from an unrecognized COB (chip on board) type USB memory.

USB (universal serial bus) memory, which consists of a flash memory that stores data and a controller that controls it, is small in size, convenient to carry, and simple to use. Because flash memory is used, information is not erased even if the power is cut off. It is one of the storage media that does not. In particular, unlike CDs or DVDs, USB memory has the advantage of being able to freely delete and store data, so it is widely used as a portable memory device. However, USB memory has a high risk of loss due to its small size, risk of virus infection, and is vulnerable to electrical shock due to the flash memory made of semiconductors. Therefore, if the USB memory is damaged or broken due to external impact, data recovery is difficult.

Meanwhile, USB memory can be divided into various types depending on the implementation type of flash memory and controller. For example, there is a general form in which the flash memory and controller are separated into separate chips and implemented on a board. Such a general USB memory device has limitations in miniaturizing the device because the flash memory and controller are implemented in the form of separate chips, but has the advantage of good durability and ease of data recovery in the event of a malfunction due to poor recognition. For example, a typical USB memory uses a TSOP-48 chip as flash memory, and in this case, the data signal output location of the flash memory chip is standardized. Accordingly, if the device is not recognized by the host due to a malfunction, data recovery can be easily performed by removing the TSOP chip used as flash memory and inserting it into a USB recovery device.

Recently, USB (universal serial bus) memory has been gradually decreasing in size, and in order to implement a memory device with the desired capacity in a small space, the mounting density of memory elements must be increased. To solve these problems, memory devices have recently been implemented using the Chip On Board (COB) process. That is, as another example of USB memory implementation, there is a COB type USB memory in which a flash memory and a controller are implemented together in a chip on board form. This COB type USB memory has the advantage of having improved performance compared to general USB memory, is advantageous for miniaturization, and can reduce manufacturing costs.

However, in COB type USB memory, the output location of the data signal of the flash memory is not fixed and the manufacturer does not provide information about this, so if a malfunction such as poor recognition occurs, it is difficult to recover data in COB type USB memory. There is a difficult problem.

In order to solve the above problem, the present applicant, as disclosed in Korean Patent Nos. 10-2127768 and 10-2127794, decapsized the unrecognized COB type USB memory to the pin-out point of the printed circuit board. After exposing the terminals, a technology was developed to enable data recovery by connecting each pin-out point and the corresponding adapter terminal to the host through a wire bonding process in which the operator connects each pin-out point one by one.

However, in the above data recovery method, the device used to recover data by connecting the unrecognized COB type USB memory with the host is each pinout point of the unrecognized COB type USB memory and the corresponding recovery device. Because the operator must connect each terminal individually through wire bonding, the wire bonding process takes a lot of time, and the narrow pitch between pin-out points makes the work difficult, and as the connection work is done manually, data is lost. There is a problem that it may be difficult to read accurately.
