What's the best way to delayer a PCB without expensive equipment?

not happening lol

A planer

As that guy said, never ever. People who retro engineer stuff use Xrays to determine topology.

swing it into the wall, after enought repetitions, statistics predict that the chance of it not breaking and just come apart gracefully, will aproach 1

i can't imagine why you would need to know the pcb traces. in every situation i can think of it would be easier to just identify all the chips and passives, beep out the important parts of the circuit and fill in the blanks.
Lets say you have a memory controller. There's a datasheet for it with a reference implementation which is likely what is implemented on whatever board you're looking at. Who cares exactly how they routed it

Any designer worth their salt obfuscates the chip markings when a prototype leaves the assembly line.
It'll work for shitty consumer electronics, but the kind of stuff that needs to be reverse engineered accounts for a dude with a continuity meter.
You can slap together an X-ray machine for reasonably cheap. If you're a vigorous motherfucker, you can blow an Xray bube for the price of a silica glass tube, some bits of stainless steel. If you have a CRT or old TV around you can use the fly-back and some capacitors to power it in short bursts. This helps it not overheat but would also mean that it takes longer to get your image.
You can use a phosphorous screen of said TV or CRT, and a very long exposure camera at an angle to get you image.
I've heard stories of people using just regular old back and white self developing photography paper and getting good results.

plain X-rays are kinda useless when there are 2+ inner layers that aren't just ground/power, you need a CT scan
Colton Reyes
X-rays AND planer
Dominic Rodriguez
diy sonic transducer powered scalpel if you make a jig that will slice every layer perfectly, will jam up on vias and any components between layers but at least you'll get to see what you're after with some effort

Santoku knife. You must be very precise.

hammer + violence

while (PCB.exists()) {
PCB.TakePhotograph();
until (NextLayerIsRevealed) {
PCB.Put_On_Belt_Sander();
}
}

Multimeter Continuity Testing every pin pad to every.
Cheap.
Slow.
Still works if done right.

LOL no. Sure there is a small minority of old fags and schizos that care about "obfuscation" but it doesn't matter for a variety of reasons.
Also, if you have a successful or at least interesting product that a rival company wants to reverse, they will reverse. It's just unavoidable. You can make the process slightly more annoying but it won't stop anybody.
If you really crazy about protecting the IP, then you do it at IC level. You make your own chips and even that is going to get cracked sooner or later if there's interest.

Decide on single style, you retarded cuck.

Get the schematics from any of the backdoors present in whatever machine the maker is using

You have no idea what you're talking about, do you?

cheap equipment and a lot of time and care.
Isaac Thompson
Just look at the gerbers
