Jim,      

Unsealed anodize would be best  but chromate conversion coating, ie Iridite or Alodine, brush applied, will work or a really clean abraded aluminum surface provided you get good wetting from your epoxy and it is compliant enough to work between the two surfaces.   How are you prepping the polyimide?

Subject:  [TN] SURFACE PREPARATION OF ALUMINUM

I'm looking for a procedure to prepare a cast aluminum (A356) core for epoxy
bonding to a polyimide PWB.  Any Recommendations?
