DETECTING A VIA STRIPPING ISSUE IN A PRINTED CIRCUIT BOARD - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17729886 Titled 'DETECTING A VIA STRIPPING ISSUE IN A PRINTED CIRCUIT BOARD'
Simplified Explanation
The abstract describes a flying probe, which is a testing device used for printed circuit boards. The flying probe has a test module and a processor. The test module measures the difference in capacitance (delta capacitance) between multiple pairs of vias on the circuit board. The processor then compares these delta capacitances to a predetermined threshold value. If the delta capacitances associated with a specific via are equal to or greater than the threshold value, the processor identifies a potential problem with that via, known as a via stripping issue.
Original Abstract Submitted
A flying probe includes a test module and a processor. The test module measures a plurality of delta capacitances associated with a plurality of vias in a printed circuit board. The plurality of vias include first, second, third and fourth vias. Each different delta capacitance is measured between a different pair of the vias. The processor compares all the delta capacitances to a threshold value. In response to multiple delta capacitances associated with the first via being greater than or equal to the threshold value, the processor detects a possible via stripping issue for the first via.
