Mobile Device Testing Non-destructive Techniques

Non-destructive mobile device testing is part of Group O’s mobile device lifecycle management services. Our non-destructive testing is part of our First Article Inspection (FAI) process and involves a variety of mobile device testing procedures designed to be fully customizable to fit the needs of individual carriers and original equipment manufacturers (OEMs). Below is an in-depth breakdown of the different types of non-destructive testing that both new and remanufactured mobile devices go through to check for compliance and verify original OEM parts.

X-ray Testing

The first step in our comprehensive testing process is x-ray testing. X-ray testing is performed by Group O’s expert technicians in order to validate that authentic OEM parts are in the proper place, like an OEM battery. 

X-ray testing also enables operators to check the OEM and remanufacturer’s workmanship, ensuring the mobile device was constructed properly and meet all standards set by carriers. If standards are not met during this time, the mobile device fails the test and images are taken of the device for further inspection or review.

IP X7/X8 Compliance Checks

Next, mobile devices are checked for IPX7/X8 compliance per the carrier or OEM’s specifications. This entails a water ingress test which uses air to detect the smallest deficiencies within the mobile device. The air is used to automatically seal any openings with a silicone plug. This is an automated process that is designed to increase efficiency throughout the testing process and reduce human error.

Oleophobic Verification

Next is oleophobic testing to verify that the new or remanufactured mobile device’s glass display has been properly coated. To verify proper coating, operators drop a small amount of water onto the display screen. If the water beads up and easily rolls off the surface of the device, the unit has been properly coated and moves onto the next stage of testing. 

If, however, the water does not bead up, instead forming a blob that moves around the glass display, that means the mobile device has not been properly coated and fails the test. Oleophobic coating is important for glass displays as it reduces water damage and protects the device from oils from the user’s fingerprints.

Radio Frequency Testing

Following the oleophobic test, mobile devices are put through radio frequency testing, or RF testing. This process confirms that each device meets OEM specifications. To test this, each mobile device is placed in an RF shield box. Each unit must be placed in the box by an operator as positioning will vary depending on the unit. Group O’s in-house New Product Introduction team ensures positioning standards.

X-ray Fluorescence Testing

Mobile devices are then tested with X-ray fluorescence (XRF testing). This testing provides external analysis of remanufactured mobile devices to verify the elemental makeup of a device’s back cover and logo material. Through this process, any counterfeit components are identified to ensure the end user’s product is safe from fraudulent behavior.

IP67/68 Testing

Finally, new and remanufactured mobile devices are tested for IP67/68 verification. This relates to a mobile device’s water submersion capabilities. IP67 testing verifies that a mobile device is able to be submerged in water up to one meter deep for half an hour. IP68 testing verifies that a mobile device is able to be submerged in water up to 1.5 meters deep for the same amount of time. This testing confirms proper waterproofing of mobile devices.

Verify and Analyze Quality Standards for Mobile Devices

Through non-destructive mobile device testing, Group O is able to verify and analyze quality standards of new and remanufactured mobile devices before they go to market.  Not only is this important to protect the reputations of the OEM brands you love, it is a critical component for remanufacturers to qualify to be an OEM partner. The bottom line is that the consumer receives the highest quality devices that meet today’s digital first lifestyle.
