Anti-static vs. conductive vs. dissipative foam?

UPDATE: I have included some basic answers inline that I received after talking in depth with an application engineer at a foam company. I think it would still really help for someone to help flush out the theory behind these answers. I am having…

Red resin in-between closely spaced PCB pads

Closely positioned components on this one sided PCB have red resin separating solder connections and underneath surface mount components. What is it? How is it applied and why do only some components have this resin separation?

Is there a way to print / draw a circuit on to clothing?

I'm looking for an alternative to conductive thread (since I lack some sewing skills). I have seen silver conductive pens but I'm wondering if they could be used for clothing?

Why do typical DC motors use brush contacts rather than just conductors?

Why do typical DC motors use brush contacts rather than just the conductors of the wire itself? Wouldn't the wires be more efficient/low wattage dissipation in that region?

is there some sort of paste, grease, spray or similar thing that helps make more contact surface for high-current battery?

I have terminals attached to a battery, which will conduct high-current (40A to 200A), and these are copper plates. As the plates, and battery terminals are not perfectly even (even if they appear to), just squeezing the contact with a screw won't…

Can I use foil as a wire for my project in tight spaces?

I am building a project that I can put a AA battery into a little compartment. The battery fits fine without anything else in it, but when I put a wire in, it gets tight. A solution that might work: aluminum foil. I measured the resistance with a…

How is saltwater able to conduct electric charge between two wires?

Say I put some wires in a container filled with saltwater, but the wires do not touch, and I connect these wires to a battery: simulate this circuit – Schematic created using CircuitLab I know that the saltwater will complete the circuit, and some…

Making conductive traces for capacitive touchscreens

This is a follow-up to this question I asked years ago. A short summary: I'm using a head pointer (see my linked question for a photo) with a tip made of plastic, thus non-conductive. The shaft is metal, and conducts well enough for a smartphone…

Chipquick SMD291 No-clean Paste Flux - Conductive?

I'm using this brand and type paste flux, and it works very well... except for one small problem. After assembling 5 prototypes, most had bizarre issues, which were resolved when the flux was removed via 91% isopropyl alcohol bath, soak, scrub, and…

How do I verify if a conductive mat is getting "Earthed"

Explaining to me about electricity is like explaining to your Grand-Ma about it. So please be kind and gentle :) I bought an Earthing Mat from "http://www.amazon.com/dp/B003RLOBOK". It includes a conductive mat to which I connect a white-wire whose…

What is the most available high-temp superconductor for samples and study?

I could only find one named Amperium on the web, but not on the eBay or any little shops. It is very interesting material with conductivity 40 times better than copper. Is it possible to buy anywhere a little sample of material like this?
