Why get a second PCB for custom keyboard?
« on: Sat, 23 January 2021, 17:05:21 »
I've recently started this hobby and will probably purchase my first custom keyboard case soon. I’ve noticed that often you can buy a second PCB with it and I’m wondering what the reasons for getting a second PCB are. I’m familiar with electronics so I’m not afraid of soldering the switches or breaking the PCB. Or is this more like a long term backup if the PCB dies in 10 years from now?

I’ve bought more than one pcb/plate for a variety of reasons before -

Different layouts (split space or not)
Different color plate
Those switches I used went out of style (not really this but lol)
Fear of having a super nice case and not being able to replace the pcb if it breaks

So yeah those are some reasons. There are probably more...

Long term backup, your PCB will probably die to something stupid and youll want a backup.

Well I don't own one, but I would assume when you're spending anywhere from $400-1k+ on a custom keyboard, spending another $50 bucks on an extra PCB is pretty marginal.

I don't think trying different switches/layouts is a valid point for me, because I probably won't be experimenting that much. I also would need an additional plate for this. If I really want to change the switches I could desolder them. So I guess it comes down to a backup board if the other one dies for some reason.

If its a custom always buy a backup PCB. Something may just randomly happen and you may end up with a brick of steel. Better be safe then not.  If its a keyboard with standard parts you can easily get i would say yeah 1 pcb is enough if something happens you can just buy a new one.

Another reason could be that the stock pcb doesn't have the features that the builder wants.

As others have said, there's less of a benefit if the PCB will be still available for purchase.

Even if the PCB doesn't stop working on its own, a backup PCB can be helpful against something as simple as an accidental spill.
