Conformal Coating Removal Pen and Machine
By Jestine Yong on March 22, 2011
What is Conformal Coating?
According to Wikipedia “Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that if uncoated (non-protected) could result in a complete failure of the electronic system. Most circuit board assembly houses coat assemblies with a layer of transparent conformal coating rather than potting.”
Epoxy, Silicone, Urethane, Parylene and Acrylic can be removed by the Conformal coating removal pen or machine

I have some thin craft copper which I am going to apply some (100kv per mm) conformal coating to on the rear side of (to act as a dielectric surface on the back of a conductive) to make some EMI material.

Usually conformal coating is used to protect the PCB from damage since it will be exposed to harsh environment...
Examples are Burn In Boards used in semiconductor manufacturing. The board is subjected to 250 deg C for 1000 hours with a device under test (usually an IC). Then after 1000 hours, the IC will be tested if it is still electrically good.

Hi Karlo,
That was a good sharing!

indeed, new information to me. thanks for sharing. is that why sometimes the solder would not stick to the soldering joints?
