shorter than the 2”-transducer arm of the wire-bonding machine. The height of the
cable connectors are less than 6 mm so that they do not obstruct the transducer arm
during wire-bonding. Any on-board components need to be at least 1.25 mm from
the bond fingers.
The layout design procedures of the SLM board is the same as described in Sec-
tion B.4, using the Allegro Design Entry CIS schematics software and the Allegro
Cadence PCB layout software. See an example of the screen capture in Allegro Ca-
