Package designers often would like to reuse an existing
package with a new die but find that the time required to insert the new die and
draw the new wire bonds is prohibitive. It seems that since you have a CAD database
of both the package and the die this ought to be a simple automatic process!
With Artwork's SWIFT you can now automatically drop in a new die into an existing CAD drawing. SWIFT will then wirebond the part either fully automatically or following a netlist that associates the die pad to the ball or finger.
SWIFT includes an analysis module that checks each wire's length, angle and spacing and reports on any assembly rule violations.
