Understanding PCB Flying Probe Test
PCB Flying Probe Test is a method used to evaluate the electrical function of PCBs by checking for open and short circuits. Unlike traditional bed-of-nails interfaces, flying probe testing employs independently controlled probes that move to the component under test.
Key Steps for Creating a Flying Probe Test Program:
Method One:
- Import and organize layer files, renaming layers accordingly.
- Add and rename additional layers for solder mask and drilling.
- Adjust test points and define unmeasured holes.
- Ensure test points are correctly positioned for testing.
- Copy test points to respective front and rear layers.
- Finalize layer alignment and spacing.
- Generate gerber files and continue the process using Ediapv software.
Considerations:
- Be mindful of the abundance of test points generated and the need for manual deletion.
- Ensure proper testing of holes to avoid connectivity issues.
- Clarify layer names to prevent confusion.
- Double-check test programs for accurate measurement points.
- Verify layer names for future troubleshooting.
By following these steps and considerations, you can effectively create a flying probe test program for accurate PCB assessment.
