Successful chip transplant on a Samsung S10e: CPU, RAM, and UFS memory moved from a damaged board (right) to a functional one (left). Phone booted and data intact! #microelectronics #repair #datarecovery
Samsung s10e booting after transferring CPU, RAM, and UFS memory to a good board Bottom of Qualcomm sm8150 cpu after reballing UFS memory which stores the data Good board prepared for receiving CPU, RAM, and UFS memory from data recovery patient. Missing a few pads, but the missing ones are not connected to anything and irrelevant.

Some high resolution photos of what I believe is a flicker/ambient light sensor integrated into the camera flash of a Samsung Z Fold 4. The grid on the right seemed a little odd. At 2000x we see a repeating pattern of "stk" 10 microns wide, which the manufacturer sensortek used to fill empty space.
Exploring the intricate world of microelectronics! Here’s a close-up of a silicon die, revealing the complex architecture and circuit pathways within. Each tiny square and line represents layers of precision and innovation. #Microelectronics #Tech #Engineering #SiliconDie Further zooming shows that the grid on the right hand side seems somewhat irregular, odd At 2000x we can see this grid is made up of a repeating pattern "stk" that are each about 10 microns wide. The manufacturer, sensortek, left a little Easter Egg in some of the blank space in this die. Zoomed out image showing the entire camera flash component along with some of the PCB it is mounted on.
