     We are planning to use OCC boards in assemblies that require the 
     installation of a bulkhead. The bulkheads are normally mounted to the 
     boards with a screw and nut. The mounting tab of the bulkhead contacts 
     grounding pads on the board.  
     
     With HASL, there has not been an issue with using Zn-plated bulkheads 
     or screws. With OCC, we are concerned that the use of Zn may cause 
     electrolytic corrosion.
     
     Has anyone tested OCC with Zn-plated bulkheads or attachments? Has 
     anyone experienced corrosion in such a case?
     
     Thanks,
