PCb surface Resistance | 18 June, 1999

There is a PCB with SMD components glued on bottomside. When I make tests for checking the resistance of glue the result is a break in the surface of PCB.

How can I measure the surface resistance of PCB surface? How can I increase this resistance?

Best Regards Eng. Sergio Luiz Vito Process Dept.
