WTB Scrap Circuit Boards

[Cariba]

Hello All,

I am looking for just a few scrap and unwanted (preferably Pinball) boards to practice de-soldering; as I need to replace a chip from a bally CPU.

Any help would be appreciated, willing to pay some minor amount for them.

Thanks,

If you don't think that you will be doing many of these and don't want to chance it, send the board(s) to Brent. Get it done right, the first time and you won't mess up the boards.

I can share his contact info if interested, I l would l just need to check my emails.

I have a couple you can have for free, I'll send you a message. I think I have a dead Bally board (79-81 era) you can practice on

Yeah I hear you, I don't mind seeing how I do in the practice sessions first at least, then if needed might go that route, I'd really like to be able to do myself and excited to get better at.

I don't mind doing this type of work and repairs, what I may not be able to do, nor have proper equipment for, is trouble shooting circuit boards.

In this case however, I already know it's just a "simple" chip swap (add a socket) to prevent a bulb flickering issue with the new/correct chip, not corrosion or anything like that (where I don't even know where all the damaged components are).

Good luck and enjoy the process.

I do know that some people have had increased success in clipping off components, prior to desoldering the legs. Of course that depends on the space available between the legs but it does make sense as there is less for the heat to dissipate to and equally important to me, you are not having to try to wiggle out a component with multiple legs. This alone can pull traces as it is likely that you haven't cleanly removed all solder.
