Is the quality of ZX 48K PCB's not the same by every motherboard?

I have here a motherboard and desolderd the ZX 80 Cpu. No problem but near the desoldert pins a lot of the conducting passes unverified to frog! I desolderes with compressed air and then with desoldering wick. :???:

On C64 motherboards this works very well.

    I'm not sure what you mean by "a lot of the conducting passes unverified to frog" (presumably you mean there's a loss of continuity between the top and bottom side of the PCB).

    The issue 4S boards (made by Samsung) are reputed to be the best. However, I've not had any particular problems with any issue of 48K board that I've had.

    I mean broken conductors.
