Dear Technetters ;

 Could I get any information for PCB manufacturing process for catalyzed FR-
4?
 I received some problem in through hole after plating that much holes were
not well plated and
 so very rough surfaces with cracks in walls.
 Does it come from poor catalyed process or Palladium defects?
 Thanks for your kind opinion.
