ok while doing some repairs and a few other bits and bobs on the mini.

i removed the dash now i have known for a while, that i have needed to renew the cicuit board, but as the old saying goes if its working leave it alone.

now as you can see from this picture, hopefully, that the board is starting to come apart and the connectors for the block connector are loose, sometimes causing little problems.

now what i want to know is can it be repaired, and how, or where can i get a new one?

thanks all

I have not seen the circuit board for sale. But I do have a very clean set of late Nipon clocks if you are struggling to find a solution.

if your good with wired and cant find another board you going use wiers and crimp connectors ? just a suggestion

You can buy the sheets of flexi copper etch from a number of electronics supliers (maplins, RS perhaps?) and you can then use the original circuit traces to etch out your own new replacement (requires etch fluid, UV exposure lights etc, available at maplins). You could even make a bit of money back on the equiptment costs by offering the same service to TMF members..

You could do as suggested, and just use some thin guage wire to replace the broken / all copper traces, which will work just as well. If you wan't to do this, just buy a cheap IDE hardrive cable (40 pin type - so 40 wires) and this will be idea for the task.

One other posibility is to find a company that offer a free (or very cheap) prototyping service, you will then have to get the circuit converted into a diagram (free software for circuit designs on the web, just google), or possibly even just a photo copy of the circuit board (copper side facing the scanner / photo copier bed scan head, otherwise the cicuits will be back to front! ).

You could also try to find someone who does electronics and has the equiptment for PCB etching, and ask them to do it for you (sorry can't help with that one, I only use bread board / strip boards).

Iv got a couple of two clock units and i could take the back of one of them for you for a couple of £.
