Advanced Testing Services for Maximum Product Reliability

Testing Services

Tengda Electronics offers a comprehensive suite of testing services to systematically validate PCBs, cables, components, prototypes, and finished products before shipment. Our 1000-square-meter testing facility has environmental chambers, signal generators, oscilloscopes, power meters, and other state-of-the-art electronic test equipment. We perform functional testing, environmental testing, EMC/EMI testing, safety testing, and burn-in to certify compliance with regulatory standards worldwide.

Functional and Performance Testing

Tengda thoroughly tests product functions, parameters, and performance against supplied specifications to verify all design requirements are met before release. Systematic testing procedures and customized diagnostics tools are developed based on the product design. Tests are repeated after any component, software, or hardware changes to confirm all functionality remains intact. 

Functional and Performance Testing

Environmental Stress Testing

We apply environmental chambers to test products under thermal, temperature shock, humidity, and combined environmental conditions. Compliance with MIL-STD-810, IEC 60068, and IEC 60721-3 standards is verified. Failure analysis is conducted on samples showing weaknesses to determine root causes and propose corrective actions before manufacturing.

EMC/EMI Testing and Certification

Tengda is equipped to conduct EMC/EMI tests required for CE marking and other certifications to meet international regulatory requirements. We test for conducted and radiated emissions, ESD immunity, radiated immunity, surge, and more. Test reports are generated to document conformity based on standards like EN 55032, EN 61000-4-2, EN 61000-6-2, and FCC Part 15 Subpart B. We can certify products for the CE and FCC marks to show electromagnetic compliance.  

EMC-EMI Testing and Certification

Safety Testing and Certification 

We provide safety testing and certification services for CE marking to satisfy in areas like laser radiation, ROHS, LVD, Machinery Directive, and Radio Directive. Testing is performed based on relevant EN, IEC, UL, and GB standards to evaluate potential materials, design, or workmanship hazards. Compliance is certified through reports and documentation binders suitable for audits by notified bodies. We also offer certification for Ingress Protection (IP) ratings.

Accelerated Life Testing (ALT) and HALT  

Tengda uses HALT/HASS chambers to conduct accelerated life and electronics product testing by subjecting products to extreme stress environments not found in standard testing. Rapid thermal changes, intense vibration, and other stresses are applied to quickly identify any weaknesses in product design or components, so corrective actions can be taken before mass production. ALT allows more faults to surface in a week than months of standard testing.

Tengda has provided quality testing services for decades and maintains advanced equipment to help clients quickly validate and release innovative products. Our offerings of consumer electronics testing and IoT testing services reduce risks, decrease recalls, and optimize product life cycles to maximize ROI. Tengda’s turnkey testing solutions verify compliance, reliability, and performance to give you confidence in your product.
