Hey steve,nice video,great info.Can you do me a favor?Can you try it on a piece of a mo-bo or an IT board with gold tracings?I think the masking is a lot thicker and potentially denser on those 2 than a cellphone board.If I don't hear anything back by the morning I'll give it a try here at the house and let try to let everyone know how it went when I get a minute.

I just tried the process on an old HP board and the results were not as good. The HP board has a layer of what appears to be acrylic or epoxy on it.
I'll do some more experimenting and see if I can find out what types of board this works on and the proper concentrations of hydroxide for each type.
For the record the board I tested in the video was not a cell phone board, it was a laptop touch pad board. Another possibility is that when I heated the board to remove the components the mask was weakened by the heat.
I noticed that the board in the video has a dull light green mask, but the HP board has a shiny thick coating. Most of the older ISA and PCI cards have this dull colored coating.

hi steve
all of your video require a log-in name and password, like the one that you have in the first entring to the site...
i tried your username and password but it's not working and can't see the video, or any other for that matter...

I performed a few more test on various board types, here's a photo of the results:
You are looking at a slotted cpu (cpu removed, components removed and split in half for comparison), a DIMM (components removed, split for comparison), and an old Vesa card (stripped one edge).
The items all stripped fine. The slotted cpu card could have been allowed to heat a little longer as some of the mask remained.
I used the same solution, adding a little water to prevent it from dehydrating but with no additional hydroxide added, for all the boards in the photo.

Steve,
I've found that alkalai solutions will severely etch glass, including Borosilicate, so it might be a good idea not to use valuable glassware, but instead, some garage sale casserole or something similar. I tried using Stainless (Inox) Steel but the solution created pinholes in the Steel after a while. HDPE works well but it needs to be heated in a water bath or use an immersion heater.
