Basic Knowledge of In-Circuit Testing: What are the Advantages of the Flying Probe Method?
This is a must-see for those who don't know the basics of in-circuit testers that you can't ask about now!
In in-circuit testing using a flying probe tester, there are five significant advantages that traditional fixture-based testers do not have. These advantages are: 1. The contact position is corrected by checking the position with a camera for each inspection board every time. There is no need to worry about adjusting the set position. 2. If there is an error due to misalignment, the contact position can be automatically adjusted, and re-inspection can be performed. There is no need for the operator to manually re-inspect, reducing false reports. 3. The contact speed can be flexibly adjusted. Depending on the area to be measured, hard and soft contacts can be used interchangeably. 4. Components that cannot be inspected electrically are supplemented with the included AOI inspection function. 5. There are no running costs, no lead time for fixture creation, and no need for storage space. By maximizing these advantages, we enable more precise and quicker board inspections, contributing to the reduction of inspection costs for our customers. For more detailed information, our sales representative will provide an explanation, so companies considering a switch from fixture-based testers are encouraged to contact us.

Applications/Examples of results
In the case of fixture-based testing, even for small-scale production boards, it is necessary to manufacture inspection fixtures, which leads to high inspection costs per board. Additionally, when using old inspection fixtures after a long time, there is a challenge of encountering defects somewhere, which takes time for cause investigation. However, this issue can be resolved with a flying probe tester. Furthermore, for projects with short delivery times, it is necessary to consider the lead time for fixture creation in the schedule, but with a flying probe tester, fixtures are not required, significantly reducing the lead time.
