My company has designed a BGA device with a FR4 substrate and copper heat
spreader.  We have had some problems and would like to talk to someone
who manufactures similar devices.  From what I understand Amkor makes a similar
device but I don't know of any contacts.  I am looking for someone
at Amkor who is involved with the design of the HPBGA .  If anyone from Amkor is
on this forum or if anyone knows of a contact, I would appreciate
a e-mail with the contact information.  Thank you.

Best Regards,

Michael Forrester
