We are planning on replacing a SMT 100Pin QFP with a COB module that will have two dies that are functionaly equivalent to the old part that will not be available. Questions: 1)Suggestions on substrate material FR-4 or something better? 2)Are there d

I spec COB using wire bond attach - 0.75um � 0.25 Gold over 5um � 3 Nickle.

Mar, The previous post makes the best point. Your finish spec depends on the COB process you plan to use. Is your process: * Gold wire bond * Aluminum wire bond * Flip chip * Er, watt
