Wolfgang:

     As you have found out, ENTEK is an insulator.  One of the most
     successful methods for minimizing "false fails" due to a thick ENTEK
     coating or a buildup on of ENTEK on the probes is to screen print
     paste onto the test pads at the same time as the paste for the SMT
     components.  The solder paste and flux will dissolve the ENTEK, coat
     the pad with Sn/Pb as a contact surface without sacrificing the
     flatness requirement necessary for fine-pitch IC installation onto
     your board.  Try that with a HASL board!

     Hope this helps.
