PC MOUNTING INSTRUCTIONS
High frequency end launch performance is dependent upon proper mounting. The following factors must be controlled
for optimum performance:

d. Use a minimal amount of solder between the contact pin and signal trace. Do not allow excess solder to build up
a. The connector should fit tightly against the circuit board edge, avoid gaps.
b. The center contact pin must lie parallel and flat against the circuit board, avoid gaps.
c. The contact pin should be centered on the circuit board signal trace.
e. Clean all excess flux and other residue from the launch area, especially between the trace and ground
or flow down the trace.
The basic steps required to mount the end launch connector to the circuit board are as follows:

connector, which acts as a seal when soldering the center conductor pin to
the trace. Clamp the connector tightly against the edge of the board. This
action compresses the insulator seal against the board edge. This
effectively creates a barrier between the inner and outer conductors,
preventing the bridging of solder.
The fixture protects the connector from damage during clamping and also
maintains the proper location of the connector’s insulator and contact. To
use the fixture, thread the coupling nut on the mating end of the connector
and hand tighten. This mounting assembly can now be held in a vice or
similar clamping device, as shown in Figure 1.
aligned with the center of the signal trace as shown in Figure 2. Make sure
that the connector legs and contact pin are held flush against the top of the
circuit board, keeping the axis of the connector parallel to the plane of the
circuit board, as shown in Figure 3.
contact pin can be bonded to the trace by using a minimal amount of
solder as shown in Figure 4. It is important that solder flows along the
length of the exposed pin, creating a good electrical and mechanical
connection. Remove any excess solder that is not required for a solid joint.

will affect performance. The completed mounting assembly should look
similar to the one shown in Figure 5.
