The tape only is for isolation and stability and not to prevent reverse engineering.

And I have to hurry creating the final schematic out of my mind otherwise the tape will prevent me of this...

I guess standard pcb... smt could burn through...

From reading your earlier posts, I figured you would take measures to keep some parts of the circuit low noise and free from interference. I can see you have two separate sections of circuitry which appear to be isolated in separate tape bundles, and there is no circuit board. The point-to-point direct soldering helps to keep the lead lengths short which may be necessary for certain components.

This made me think you used this kind of construction intentionally to minimize the conductor lengths, while saving time with circuit boards. I figured if you wanted to maintain the same short lead length on a production model, you would choose SMT. But these are harder to work with when hand-built, so a well-designed circuit board may work better.

Actually this prototype construction method is not a bad idea. The last LRL construction I was involved with was wired with the same method. Too bad the circuit designer was banned from the forum before I finished the LRL. It was said to be good for detecting TVs from the couch, and static fields from a large distance.

Best wishes,
