Technetters/Fabricators, My supplier is having a problem with yield on our backplane (~.200", SMOBC/HASL). It seems to be centering around hole plugging from HASL. FHS are .024", .028", .032" for both pressfit and pth connectors. Is this a typical problem for these requirements?? If so, what are other finishes to consider to achieve higher yields but not introduce large cost adders?? Comments and suggestions appreciated.
