Can electromagnetic field blow electronic circuit boards?
The short answer is yes. However, many circuit boards generate electromagnetic fields or are part of systems that intentionally or unintentionally generate fields and suffer no harm. Electromagnetic fields can induce voltages on wires or electrical pathways within the circuit board if they are : A) of sufficient strength, B) If the field is oriented a certain way, and C) if the circuit board has no shielding. These induced voltages could damage components on the circuit board.

How do you remove coating on circuit boards?
That will depend on the type of coating used as there are many, some of which are trivial to remove whereas others cannot be removed without using means that irretrievably damage the circuit board itself.

Just make sure to wash off the stripper residue with good quality circuit board cleaner (not water).

What does a better circuit board do on a paintball gun?
"better" is a matter of opinion but largely aftermarket boards will offer more firing modes and more in depth programing over stock boards. That aside, the vast majority of stock boards today have everything you will ever use on them, all major tournament modes and many have a user defined mode already. in the last handful of years we have seen a decrease in the number of aftermarket boards largely because stock boards are getting so good.
