yeah , any more information on cost other than it's more expensive than a regular battery , but um but if we're using a an i a cheaper chip , then it'll even out , I think.
But over time
Um circuit boards. Um yeah , I got a whole bunch of information on how circuit boards are produced. They're  they're thin fibreglass with copper wires etched on to them , and di I think they're quite easily printed on by machine , which is chip on print is where the machine prints on the wires and solders it all together for us.
I don't really know what to tell you as far as decisions. I wasn't really given any options , I was just given that this is how they're done.
