Analyzing PCB layouts for pad-to-pad and pad-to-via spacing violations is time‑consuming and error‑prone, often leading to costly rework after DFM submission.
Run the analysis script with an optional threshold parameter to generate a filtered report of spacing violations.

To check PCB pad spacing violations, run the provided Python analysis script to compute distances between all pad pairs and generate a filtered report of gaps below your configured threshold. This catches spacing issues before DFM submission to manufacturers like JLCPCB.
Yes, you can filter pad-to-via spacing violations by net to separate intentional electrical connections from true clearance issues. The analysis script maps each detected violation to its source location for quick fixes during PCB design review.
You need a Python environment to execute the pad analysis script. The tool requires no additional dependencies and computes all pad-to-pad and pad-to-via distances using an optional threshold parameter to produce the filtered violation report.
The best way to configure threshold distances for PCB pad clearance checks is passing an optional threshold parameter to the Python analysis script. It automatically flags any pad or via gaps falling below the specified value before you submit files for DFM.
Automated distance calculation helps with PCB design review because manually analyzing pad-to-pad and pad-to-via spacing is error-prone and time-consuming. The script flags gaps below a configurable threshold, preventing costly rework after DFM submission.
A limitation of using Python scripts for pad spacing violation detection is that you must manually configure the threshold parameter and filter results by net. The script identifies gaps but requires hardware engineer review to distinguish true violations from intentional connections.
