Chip-Off for Digital Forensics

The reliable gathering and maintenance of data evidence is the overriding requirement for law enforcement professionals engaged in Digital Forensics. Mobile devices provide information (texts, emails, phone calls, GPS etc.) relative to a suspect's whereabouts and communications provide important evidence for an investigation.

Chip-Off is an important technique for digital forensics labs that need to access data from mobile devices, such as cellphones and tablets by matter subtraction.

Older thermal chip-off techniques, using a heat-gun and a tweezer, have low yields and can lead to an unacceptable loss of data. ULTRA TEC has developed a range of mechanical machinery (precision sawing, milling and flat grinding) that keep process temperatures low and can prepare NAND Flash devices from all directions -- leading to consistency between users - and the highest obtainable yield -- with maintenance of crucial data after matter subtraction.

To meet modern law enforcement requirements, ULTRA TEC offers an extremely affordable set of tools, the ‘THIN BLUE PRODUCT LINE’, which cover the bases of decapsulation, chip grinding and milling.

For higher specification requirements we offer the ASAP-1 range of milling equipment – offering deep sub-micron thinning and polishing - along with the well-established ULTRAPOL Advance Flat lapping and grinding machine, with advanced angular positioning features.
