Here's a pic of the bottom crud in my AP bucket.
I'm trying to run the bucket reaction for as long as it keeps working. Several pounds boards and fingers have run through it.
Now running air pump this crud is showing up more, last 2 clean/rinse outs.
Couple questions would be:
Is this stuff something to do with the copper chloride 1 and 2?
Is the copper content becoming saturated?
What about the nickel plate over copper, where does that go?
Does it matter, meaning does this effect my balance ability of the etch solution?
Checking the cards closely I have sprayed this crud off both sides of card surfaces, somehow it chooses to build on cards with less circulation in the bucket.
Also interesting is it appears to build-up right on top of the gold plate, is that normal?
Also some of the thicker foil traces still look like they have copper attached to them.
This is causing a longer time HCl prewash, of the foils.
Guess it doesn't matter because the foils need to be real clean anyways from copper.
Still the way I'm doing this, not that its time consuming but its taking a long time. I'm acid soaking and allowing 24hrs inbetween rinses.
The pile in the large glass measuring cup is growing considerably as I keep adding foil to it when I rinse more out of the bucket.
As long as I'm pulling green color out from the foils I guess its okay to keep rinsing in HCl?
