Hello, friends
A gold stripping solution may take some time,
or sometimes hours. Depending on the thickness
of the gold plated material. Today I will
test with the old CPU Computer Chip and gold
fingers electronic circuit board.
gold stripping solution in a dry form and
upon dissolving in water adding cyanide, it
worked very nicely to strip gold layers from
semiconductors without damaging the substrate.
Time 1 minute 30 seconds for gold fingers
electronic circuit board. Gold will be made
into a solution. Oh and other materials remain
the same.
I will test with the old CPU Computer Chip
Ceramic.
Let's see how long it takes.
6 minutes still have a little gold stuck.
It takes time Longer solubility For thicker
gold.
I will soak into the gold stripping chemical
further.
10 minutes still have a little gold stuck.
I will soak into the gold stripping chemical
further.
45 minutes, you will see the gold pin CPU
that is immersed in the stripping gold chemical.
On average, from my work for the Ceramic CPU
30 to 1 hour 4 8 6 ,3 8 6 Intel pentium pro
and others with gold next to Ceramic
