When the circuit board is hot with the electric iron, some leather can not affect the work? Can you scrape the circuit board with a knife?
What's the leather part? Paint or copper?
Skin is no problem, as long as there is no broken copper does not affect the function, if the patent under the copper water clock out, there may be damp rust oxidation, if the conditions can make some green paint to prevent oxidation.
Skin problem, skin is broken wood useful! That leather is circuit
