Device Testing

Make Confident Product Decisions

Device quality can affect customer satisfaction, return rates, warranty claims, supplier performance, and brand reputation. Independent testing provides the data needed to evaluate whether devices meet established performance and quality requirements.

Group O executes standardized and customized testing procedures based on the device, program, supplier, and defined testing criteria. Results can help quality, engineering, and procurement teams evaluate device performance, investigate concerns, and determine appropriate next steps.

Device Testing Can Support:

• New device evaluations
• New model qualification
• Supplier evaluations
• Remanufacturer qualification
• Process change validation
• Product performance verificationField failure investigation
• Repair quality evaluation
• Component verificationOngoing quality monitoring

Evaluate Devices Without Compromising Usability

Non-destructive testing assesses device functionality, components, connectivity, construction, and condition while keeping the tested unit intact.

Group O performs non-destructive testing as part of First Article Inspection and other quality programs. Testing procedures can be aligned with client specifications, device requirements, supplier standards, and identified quality concerns.

• X-Ray Testing: Evaluate internal device construction and help verify the presence of expected original equipment manufacturer components without disassembling the device.
• IP67 & IP68 Testing: Evaluate device resistance to water ingress based on defined testing requirements.
• Oleophobic Coating Testing: Assess whether screen glass coatings perform as intended.
• Radio Frequency Testing: Evaluate network connectivity and radio frequency performance.
• XRF Testing: Analyze material composition to help identify counterfeit or noncompliant components.
• Functional Performance Testing: Evaluate speakers, microphones, light sensors, power, connectivity, calls, texts, sounds, screens, buttons, and other device functions.
• Visual Inspection: Identify cosmetic concerns, assembly issues, surface defects, and other visible conditions.

Understand Device Durability & Failure Points

Destructive testing subjects devices to controlled stresses to evaluate durability, identify structural weaknesses, and understand how products respond to impact, repeated handling, water exposure, and other conditions.

These tests can support product development, supplier evaluation, manufacturing quality, failure investigation, and quality benchmarking. Findings help clients understand where and how products fail so they can determine the appropriate response.

• Drop Testing: Use automated testing and slow-motion video capture to evaluate structural performance during controlled drops.
• Tumble Testing: Simulate repeated drops and handling conditions that devices may experience during use.
• Submersion Testing: Evaluate device resistance to water exposure under defined testing conditions.
• Impact Testing: Assess the strength and durability of screens, enclosures, and other device components.
• Teardown Analysis: Inspect internal construction, workmanship, components, and potential areas of noncompliance.

Engineer-Developed Tests For Your Devices

A device testing program can be developed around the product, lifecycle stage, supplier, and quality concern.

• New Product Evaluation: Evaluate devices before production, approval, or deployment.
• Supplier Qualification: Compare device performance against established supplier requirements.
• First Article Inspection: Test initial samples before broader production or distribution.
• Process Change Validation: Evaluate devices following manufacturing or process changes.
• Field Failure Investigation: Test returned samples to investigate reported conditions.
• Remanufactured Device Testing: Evaluate device functionality, construction, and quality after remanufacturing.

Investigate Device Problems

When products fail in the field, testing can help determine whether the concern is isolated or may indicate a broader product, component, supplier, environmental, or process issue.

Group O can receive failed-device samples, perform visual and functional evaluations, conduct teardown analysis, and use targeted testing to investigate potential causes. Examples may include evaluating water ingress, component condition, structural damage, connectivity, workmanship, or repair quality.

Testing findings can support additional investigation, test development, supplier discussions, corrective actions, or ongoing quality monitoring.

Field Failure Testing Can Include:

• Returned-device evaluation
• Failure reproduction testing
• Functional testing
• Water ingress evaluation
• Teardown analysis
• Component inspection
• Structural evaluation
• Comparative sample testing
• Repair quality testing
• Findings documentation

Test What Matters to Your Product

Standard testing does not address every device, quality concern, or intended use. Group O can execute custom testing procedures developed around specific devices, requirements, suppliers, failure modes, or operating conditions.

Testing requirements may define the sample set, equipment, test method, data collection process, acceptance criteria, and reporting format. Documented instructions help create consistency across samples and repeated testing activities.

Custom Testing Can Support:

• Unique device requirements
• New product introductions
• Supplier comparisons
• Suspected failure conditions
• Component concerns
• Product or process changes
• Repair validation
• Performance benchmarking
• Pilot testing programs
• Ongoing quality programs

Create Consistent Results

Reliable test results depend on more than equipment. Testing professionals need clear procedures, controlled processes, appropriate workspaces, and consistent documentation.

Group O’s industrial and reliability engineers support the development and implementation of testing processes. Detailed test instructions help technicians perform procedures consistently and provide documentation that can also support client, supplier, remanufacturer, repair, or testing operations.

Process Support Can Include:

• Testing workflow design
• Documented test instructions
• Testing station design
• Equipment integration
• Sampling requirements
• Data collection procedures
• Quality controls
• Technician training
• Process implementation
• Continuous improvement
