Dear si-listers:
 As Gold wire price keep increasing in recent year, we are working on
evaluate 0.9mil,0.8mil, and 0.7 mil gold wire for wirebonding MCP
package. But we have some SI concerns if we reduce the gold wire
diameters although our current product speed is only 133MHZ . Does
anyone have study this before,and come out design rule Gold Wire
Diameter Vs max wire length?
Regards
Davis
