Assuming I am understanding your comment, no, barrel plating will not affect conductor spacing.
And yes, go with the Saturn software. It's not without its faults but it does the job

Victor,
There are several online ones but I would recommend you download the free Saturn PCB Design PCB Toolkit.

Fellow TechNetters:
Is there an inter active online electrical conductor spacing calculator in which you plug in numbers and some sort of response is provided?
Perhaps a CADCAM software.
Is the PTH copper barrel thickness plays a part in this scenario.

Hello Technetters,
I am trying to interpret the electrical clearance requirements in the IPC2221A standard, under section 6.3.
Table 6-1 lists minimum spacing requirements for various voltage ranges between conductors.
The table indicates that this is for AC or DC peaks.
I am trying to interpret that last part.
Our application has a tracking power supply that provides a variable DC output voltage. The average DC voltage is between 16 and 30V, but the peak instantaneous DC voltage exceeds 31V.
In this case, should I be complying with the minimum spacing requirements for 16-30V, or should I be complying with the minimum spacing requirements for 31-50V.
I guess I am not clear what the intent of the voltage thresholds is.
Thank you for any help or insight.
