Introduction

Chip-off technology is an advanced data extraction and analysis technique which involves substantially removing chip from a theme device using specialized equipment and then acquiring the data. Chip Off technique can be used for smartphones and other digital devices that hold data using flash memory technology (Digital Forensic Corp, 2018). The Chip-off system is relatively successful on devices that have sustained physical damage and aren't functional. Chip-off is an invasive forensic acquisition which needs specialized technical tools and experts to soundly remove the chips, produce forensic images of their contents, and duly realign their contents into coherent data. Taking out the chip from the device needs microscope precision skills, making any small mistakes will result in losing all data permanently. After removing the chip connection with the system is done with the help of smartphone kit adapters.

Chip unsoldering is the most significant part of the chip-off process. The chip mustn’t be overheated as it will delete all data. It's recommended to use the rebuilt station. Even the best-rebuilt station with an automatic temperature regulator allows unsoldering chips with safety. To extract a chip it's recommended heating it to 240 °C then use a blade to extract it from a smartphone board. NAND non-volatile storage is found on the retrieved circuit board, using appropriate heat and chemicals, the microchip is physically taken out. The chip which is physically removed is cleaned and the forensic image/dump of the chip is then acquired by using various imaging softwares like Oxygen Forensics, XRY, Belkasoft, Magnet Forensics, Autopsy and using desired smart phone kit adapter it's connected to the PC. With the help of available software's, in-depth analysis is carried out and valuable artifacts from the Chip are retrieved (www.ilearncana.com; indianexpress.com).
