Project Three Title: Methods for cleaning water damaged devices Subtitle: Testing the methods for cleaning water damaged devices. Description: Research project examining the industry methods for cleaning corrosion and sediment buildup from mobile phones that have been submerged and damaged by water exposure. Hypothesis: As the duration of time increases that a water damaged phone waits in evidence storage to be prepared for data acquisition, the corrosion and sediment buildup increases exponentially. Scenario: A defined set of identical mobile phone devices will be exposed to fresh water submersion for defined amount of time. A control device will be maintained for comparative examination. At the end of the water submersion exposure, the devices will be retrieved and processed according to various defined industry methods for cleaning, drying and stabilizing devices. Device and PCB damage will be documented with digital SLR and 20X microscope camera photographs. Water samples will be retrieved at initial submersion and device retrieval to capture the following variables - temperature, pH, TDS (total disolved solids) and EC (electrical conductivity). Submerged duration: TBD Submerged liquid: Freshwater lake Expanded research: If interest and support exists for collaboration, project can be expanded to included brackish and saltwater submersions with identical scenarios.
