Lol!! Where did you get this pcb? Maybe you can find the components list there.
Just uploading your pcb here for eveyone to see.

Hi bashar, your mail is too hot to get lorens 5 schematic.

Interesting!
There is absolutely no way one could clean all that black tar like substance to reveal the underlying components.

Wrong!
There is method!
Only need patience and much spare time.
Freeze it and than heat it fast.
Than scratch and peel bit by bit.
Than again deep freeze and fast heat....and again and again...until done!
Also bee ready to destroy some of components during that process...
The hell with components! They are replaceable!

I think this is better than a patent

abbas, now you are aware why folks so like to build Delta Pulse

better is a tiny bird in your hand... than a biggest pie in the sky

Hello forum,
Thanks Ivconic to remember at the forum the technic to put away all this **** black resin.....just patience and a little time and you can clean very well this pcboard ,,,i have used with great success this method in many time!!! because i hate to not see the board for trace it...
Have a good time,
alexis.

This looks interesting ...why dont you get it x-rayed and put the images here ,we should be able to work it out from there.

X-Ray images can't resolve the markings on die surfaces.
I don't think there is a non-destructive way to identify the components except for maybe some advanced high-resolution penetrating 3D imaging technique that is out of reach.

I used to think this is impossible, but then I saw it done. It's more of a question of patience than anything. I have not tried it, but this stuff is reported to work with some resins softening them considerably;

http://en.wikipedia.org/wiki/Methylpyrrolidone
(it has to be this stuff, paint stripper won't compare)

Outside of that, Ivconic is right. A heat gun is your friend. And maybe a diamond tipped tip dremmel tool. Maybe some dry ice. I'd stay away from liquid nitrogen as it could crumble the whole thing (as well as fingers and toes!).

If there are no chip numbers, a rough schematic can still decode function. After that there have been others who take a look at the die under a microscope.

Safemakers never guarantee an unbreakable safe, only a "tool rating" of how long it is "tool resistance" (usually in minutes). Such is the same as potted electronics. It's just a question of time and resources.

Here's an interesting story about one potted game board;

It really would help to have an xray to have an idea what was under the stuff you were digging out and know what to expect.

Wow!
There's no stopping some people.

Xray should be fine and not expensive...What about a CT scan probably expensive but you should get good images.

abbas has shared the layout, look above. there is not need to xray PCB.
