What are Pathways to Exceptional Test

What are Pathways to Exceptional Test

To ensure that a device delivers the promised performance and it is safe to use, testing is a must. Whether you are a software developer or you manufacture electronics, testing is a necessary expense in all industries. In addition to testing the limits of the device under test, you can use it for the following as well. 

  • You can identify weaknesses and defects in the device. 
  • You can predict failures. 
  • It helps in searching for the design’s boundaries.    
  • You can identify something the device can do but you were not aware of it. 
  • You can stretch specifications.
  • Verify the product’s long-term characteristics. 
  • Production process optimization 
  • Testing limitations of the environment.

Test determines whether the device is good or bad. You can also use tests to get a competitive advantage. However, testing is not simple. There are different techniques and technologies used for testing. You need to know how to optimize tests and make the best use of the ATE Driver, ATE comparator and so on. There are different testing methods with pros and cons. You also need to be aware of the following: 

  • Choosing the right instrument 
  • Software architecture
  • Hardware architecture 
  • Computer I/O and connectivity               
  • Test system assembling 
  • Throughput maximization 
  • Deployment optimization and maintenance

You need a test-system design process to design a test system to get results. You want the results to be reliable and repeatable. In addition to meeting your throughput requirements, it should also be within your budget. The product life cycle has the following three primary sectors that require test: 

  • Research and development 
  • Design validation 
  • Manufacturing 

Discovering weaknesses in the product earlier is good for you. The consequences are less expensive. Different product life cycle stages have different test requirements. First of all, testing is done to verify the viability of the design concept. You need some test instruments for quick measurements. Research & development engineers also need a software analysis tool. You can connect your PC to a set of instruments or a single instrument. The next thing you need is the right software. 

Once test results show that the design is viable, you need to find its weaknesses and limitations. This is where you need the design validation system. You need the automated test equipment to reduce dependency on the expertise of the operator and make results more repeatable. You also need software for design validation testing. This software provides you with tools for control and analysis and to create a repeatable measurement process. Design validation uses the instruments used in the research and development bench system. You can compare the initial R&D measurements and design validation measurements. Manufacturing tests require a programming environment. This enables the extraction of the highest throughput. Key concerns in manufacturing are repeatability and reliability. You can use the same equipment in the following: 

  • Research and development 
  • Design validation   
  • Manufacturing 

The research and development engineer can assist during the manufacturing test. When it comes to electronic tests, you need more than coding instrument commands for automation. The complete test includes test-plan documentation, software, cables, and fixturing.
