I think all boilers are makes to avoid bar Vaillant & WB, simply on
grounds of reliability.

The PCB on my Viessmann is made to an excellent standard. I know this
because I've replaced a PCB type fuse on it. But then, so are most goods.
I've never really come across one I'd describe as being made from a poor
quality PCB material.

Of course like all PCBs they can have burnt etc tracks if not fuse etc
protected, and you have a component or whatever fail short circuit. Or it
gets badly overheated.
