Advanced BGA Chip-off Forensics

The Advanced BGA Chip-Off Forensics Class provides students with a comprehensive education into performing forensics on BGA memory chips used in today’s mobile devices.


Students graduating the class will gain core competencies in:

  • Properly Removing a BGA Chip from a Device
  • Handling and Preparing the Chip to be Read
  • Reading the Chip to Acquire the Data
  • Applying Tools and Techniques to Decode the Data
  • Practicals on the Chip-off process using feature and smartphones, as well as a locked unencrypted Blackberry.
  • Utilizing forensic software to recover the logical and physical data dump


The five-day class provides students with the skills required to properly remove BGA memory chips from a variety of mobile devices, prepare the memory for read, and use chip-reading equipment to acquire the data. Students will spend the first 2 days understanding the structure of devices and applying the best practices of chip removal, so as to prevent damage during chip extraction.Understanding the difference between memory structures -from mobile device, to tablet, to SSD hard drive – and how chip-off can be utilized to acquire data from a growing number of devices – the class enables examiners to get a handle on the growing trend of BGA memory use.

In the chip-reading portion of the class, students will learn the fundamentals of memory structure and how to utilize the tools available to read the memory off the chip.

Students get a complete hands-on experience with a range of devices and chips, from burner phones to today’s latest smartphones.  Practical lessons include breaking down and reading a chip from a password-protected, and in some cases encrypted BlackBerry device loaded with data. After acquiring the raw data acquired from the removed chip, lessons in how to best apply todays tools and other techniques to decode the data follows.

Students taking the Chip-off class should possess advanced skills in data analysis and be comfortable working with raw data at the post-acquisition phase of the course.
