A Quick Voltage Question For The Expert.

[WLS]

Hi Everyone,

I had finally received and assembled all the parts for my Deluxe Electric Mistress. Made my first PCB using the template from GGG's site. Did a simple modification by removing the 18 volt transformer and placing a 1044 charge pump. Before placing the SAD1024A chip I decided to check pin voltages.

My question is how many megavolts is too many for a pin that should be at zero with out the SAD1024A in place?
Ground is still at zero.

I looked into the components and cleanliness of the board and narrowed it down to the traces must be a tad too close to each other.

The highest reading is 254 megavolts.

Am I just being too cautious and should not worry about it?

Besides that everything looks good enough to put the SAD1024A in place and start adjusting the trim pots.


Thanks,

Bill

Megavolts? Step away from the Tesla coil!

Assuming you mean millivolts I'd be inclined not to worry about that too much. Check for shorts between tracks, even run a scalpel blade between them to make sure there's not a little filing or similar partly bridging them.

Sorry for the misprint yes, I ment millivolts.

I already checked and used contact cleaner with cotton over all of the traces. I found this to be a good pratice after soldering. It picks up any residue and clippings that may remain on the board.

Again, thanks for the reply.
