PO Box 126257, Benbrook, TX 76126, USA. Potting is usually an epoxy, which usually cannot be removed either chemically (dissolution) or thermally (melting it so you are left with mechanical (chip away at it). Many electronic assemblies, especially lower those in automotive and marine industries use potting compound which act as a protective coating. Unfortunately, patenting was not an option due to several factors.

But, how can one protect a circuit design from IP theft and reverse engineering? Cabe, this content has been marked as final. But perhaps I am not learned in the art of corporate espionage. If you know have access to some chemicals and can chip off small samples of the epoxy, you could give it a whirl).

Just by looking at the PCB you could easily see the layout, the chips used, and component placement. The shiny paper on copy top likely forms some sort of EMI shield to reduce interference it may cause or receive. Also looks at the need for a fume hood and respirators with organic ipod vapor cartridges! Some rare epoxies are susceptible to attack by extremely aggressive organic solvents (dichloromethane, xylene, etc.

My solution: Pot the electronics. I recently developed a system for a company, and they were concerned that the circuit design could easily be stolen.

A property of many (all?) epoxies is the glass transition temperature which can be exploited. I figure, might as well make it as hard to reverse engineer as possible. The MDS is very droll when it says it is a sensitive chemical. That is guaranteed to remove epoxy, very likely in very small pieces if it has any contact with heavy metals like lead as well, and it can make compounds that react badly when exposed to stimuli like shock, light or even vibration. I looked at the stuff used as a sequence to strip and was a little worried looking at the ingredients used in the various washes. We use a soldering iron and then slowly remove the potting.

Mixing: Mix the measured Parts 'A' and 'B' components in a clean, dry container. The mix ratio will be by volume and it cannot be over emphasized that proper mix ratio be strictly adhered. This block appeared to contain the CPU, program code, and possibly some other things, like address decoding.

Before I dumped the code out, I traced out the circuit from the bottom using a meter. As the epoxy fills in, it will push air bubbles out that will float to the surface.
