PCB protection against Reverse engineering
PCB protection against Reverse engineering
(OP)
Is there any way to protect my PCB against reverse engineering.
The only way I found is to encapsulate my PCB into epoxy. I also red that it makes reverse engineering harder but not impossible.

the part# of other standard parts so the copying is easy
just doesn't work. How much frustration is necessary
to reverse engineer a wellknown off the shelf part ?

layer PCB with "standard logic IC-s". Being on limited
budget they bought one, made a layout DWG and a BOM,
cut off the parts and generated wire list and copied the
PCB.
They stuffed the first thousands board before starting to
test, hoping that most would work but none of them did.
At this point they tried to draw a schematics -- it didn't
make sense. Getting desperate they rented a logic analyser
and spent their remaining time and money trying to
understand. When they found out that some of the IC-s
were custom ASIC-s, it was too late...

However, we designed a power output with a base-current starved transistor so that under short circuit conditions the transistor would heat but allow time for the external fuse to blow. They substituted a transistor with higher beta that was cheaper. On their module, the transistor would blow protecting the fuse!
Just because somebody copies something doesn't mean they get it right.

Of course even that could be x-rayed and forensically examined, but these were in an early cable TV system mounted outside on someone's house. they just wanted to keep the average Joe from trying to steal cable service, and be sure that any tampering was evident.

The company also built very good wide bandwidth amplifiers (to gHz). To keep them from being copied, they removed the manufacturer information from the comonents. It worked.
