Chip-Off for Digital Forensics

Cold chip-off techniques for producing readable NAND-flash chips for data extraction, used in the retrieval of mobile data. Made in USA and used in labs around the world.

Cold chip-off techniques empowering the retrieval of mobile data

The 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 professionals who need to access data from mobile devices, such as cellphones and tablets by matter subtraction. Older thermal 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 – known as “Cold Chip-Off” – and can prepare NAND Flash devices from all directions – leading to consistency between users, and the highest yield – with maintenance of crucial data after matter subtraction.

Which chip-off systems are right for my lab?

Ultra Tec is pleased to offer you cost-effective sample prep equipment with the minimum requirements for spare parts and ongoing maintenance – no nasty pricing ‘surprises’ down the road.
