When a PCB fails it is often the case a new one is required. Usually they're
expensive or worse still - obsolete. A whole machine could be rendered useless
if a replacement PCB is not available. There is, however, the possibility a
board can be repaired.
Boards that have become obsolete may contain components still available today.
Provided the components are identifiable, there is a very good chance a repair
is possible.
If you are spending a fortune on replacement PCBs or discover that the board
is obsolete, why not contact me and I'll see if I can help. Often, it is more
economical to replace the faulty parts than to replace the entire board. You
wouldn't replace your car every time a headlamp failed, or a tyre punctured!

Unfortunately, not all boards can always be repaired especially those containing
microcontrollers (single chip computers with proprietary software built in)
or specialised components that are no longer available. Manufacturers often
secure their software within microcontroller ICs to protect their intellectual
property. Should the microcontroller fail, only the original equipment's manufacturer
is likely to be able to help - usually with a new PCB. However, in my experience,
microcontroller failure is rare even although other components around it may
have failed.
Boards covered in really thick lacquer (1mm or more) or set in a block of resin
are usually not a viable repair due to the labour involved gaining access to
the components.
