3 Mounting the Launch
24 Keysight 11923A Operating and Service Manual
Mounting the circuit inside the package
1 Clean all surfaces with alcohol and blow them dry with filtered compressed air.
2 For the best match, place the edge of the circuit 0.022 ± 0.008 mm from the end of the outer
body of the launch. Refer to Figure 3-2 .
3 Slide the circuit under the launch pin. Align it so that the launch pin is directly over the signal
trace.
4 Affix the circuit to the package body with electrically conductive epoxy.
5 Complete the signal path by soldering the launch pin to the signal trace.
OR
Complete the signal path by gold ribbon bond attachment. For best performance, size the gold
ribbon to match the dimensions of the launch pin and the signal trace.

CAUTION
Do not overheat. The dielectric material in the support bead is capable of withstanding 125 °C for
prolonged periods and 150 °C for short periods.
NOTE
If solder is used, it is important to control the volume of the solder flow to match the size of the
launch pin and the signal trace. Be careful to avoid too much solder (capacitive) or too little
(inductive).
