I have a project that I am working on and would like some input from anyone that has some knowledge on High Voltage Arcing on PCBs. Problem: I have a PCB that is enclosed in a plastic enclosure that has metal pins and switch that extend to the outs

My first attempt was similiar to that. It was a straight ground trace running past the circular pads that were recieving the shocks. It was hit and miss when the arcs would occur. When I cut notches in the trace so the ground line had a point next to

Yes, you can rework your thermocouples, but consider using a method other than arc welding. Arc welding can join thermocouples, but it uses a filler. The filler adds a third material that affects the slope of the thermal profile. We rework our the

Yes. Ceramic is much better. We use FR4 in fairly high voltage circuits. What are the particulars? * Where are you arcing * How many layers, prepreg, etc

So, what is the battery going to do when you push your 'high voltage' through the 1-2 ohm internal resistance of the 9V battery? How about you doing a Google search on ... esd protection circuit?

Is conformal coating necessary?

Electronics Forum | Thu Mar 08 01:19:16 EST 2001 | Mike Moninger

The environment essentially defines the need for coating. "Inside" may mean inside a men's locker room with attendant high humidity or inside a climate-controlled clean environment. Conformal coatings offer protection against moisture, fungus, chemi
