What is Test Reliability in ORT Ongoing Testing Services

ORT ongoing reliability testing services refer to testing and verifying the reliability of products. The research finds out the weak points of the product with limited samples, time, and usage costs. 

ORT environmental reliability test services are the general term for various tests conducted to understand, evaluate, analyze and improve the reliability of products. ORT ongoing reliability testing is an effective method to eliminate early product defects, increase or test product reliability levels, test product reliability indicators, and evaluate product life indicators by imposing typical environmental stresses and working loads. According to the needs to be achieved, different types of ORT ongoing reliability testing can be carried out during the design, development, production and use stages of the product.

ORT Ongoing Reliability Test Services FAQs

Q: What is reliability design in ORT ongoing reliability tests?+ -

Essentially, DfR is a process that ensures a product, or system, performs a specified function within a given environment over the expected lifetime.

DfR often occurs at the design stage — before physical prototyping — and is often part of an overall design for excellence (DfX) strategy. But, as you’ll soon find out about reliability test design, the use of DfR can, and should, be expanded.

Q: How we can avoid product failure during reliability test design?+ -

Mechanical environment: improve the strength of the product structure, select higher standard devices, or protect the device structure through external means.

Electrical stress: reduce the electronic stress of its own equipment and reduce the external interference electronic stress

1. Identify and improve life bottlenecks

2. Improve stress standards

3. Improve the use environment

4. Effective isolation: electrical isolation, functional isolation, spacing isolation or shielding.

5. Reduce the effect of failure

6. Appropriate over-design of passive devices

7. Design a replaceable protection module

Q: What is reliability testing with example?+ -

Reliability testing is the activity performed to evaluate the functional reliability of a product over a specified lifetime in all environments of intended use, transportation, or storage. ORT reliability testing is to expose the product to natural or artificial environmental conditions to undergo its action to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and to analyze and study the degree of influence of environmental factors and its mechanism of action. Environmental reliability test services include different types of reliability testing: aging test, temperature and humidity test, gas corrosion test, mechanical vibration test, mechanical shock test, crash test and transit drop test, dustproof and waterproof test, packaging pressure test, such as high pressure test and many other environmental reliability tests.

Q: How do you improve test reliability in ORT ongoing reliability test?+ -

  • Select reliable and appropriate components

  • Select reliable and stable circuit in the reliability test design

  • Carry out a lot of ORT test and verification in the design, and provide the design limit of the product.

  • Do a good job in DFMEA, and make design prevention for the possible failure.

  • Design the process (TS16949) and DOE

  • Product design fully considers manufacturability and maintainability 

  • Modular or tolerance design  

Q: Is reliable test always valid?+ -

An effective reliability test should be able to effectively find problems in the product structure and function during the ORT testing, and improve the product through the problems found in the test. The product can be routinely tested according to the relevant product test standards. If it passes, it means that the ORT test plan is valid and the product meets the standard requirements, otherwise it is invalid.

Q: Why do we need product ORT ongoing reliability test?+ -

ORT reliability testing refers to the ability to complete the specified function in the specified time and under specified conditions. Mainly have the following 3 aspects

(1) Find various defects in the product design, components, parts, raw materials and craftsmanship.

(2) Confirm whether it meets the reliability quantitative requirements or evaluate the reliability level of the product.

(3) Environmental reliability test services obtain various other useful information.

Q: How do you measure reliability of a product by ORT ongoing reliability test?+ -

The measurement indicators of product reliability ORT testing include reliability, failure degree, failure probability density, failure rate, average life and reliable life, and average trouble-free working time.
