Module 4. Electronic fundamentals

In a printed circuit board , the surface resistance testing is

  • insulation resistance between adjacent printed conductor.
  • the resistance between the two conductors.
  • between the board and the conductor.

Explanation

Surface resistance testing of a PCB checks the insulation resistance between adjacent printed conductors, confirming that contamination or moisture has not created leakage paths across the board surface. It is the isolation between neighbouring tracks that is measured, not the resistance of a single track or of the bare board alone.

funcaul asking:

Please kindly explain. Also can I get a link or material where I can read up on all the modules.thanks.
