High Frequency SMA End Launch Connectors
Mounting Instructions
PC MOUNTING INSTRUCTIONS
High frequency end launch performance is dependent upon proper mounting. The following factors must be controlled
for optimum performance:
a.
The connector should ?t tightly against the circuit board edge, avoid gaps.
b.
The center contact pin must lie parallel and ?at against the circuit board, avoid gaps.
c.
The contact pin should be centered on the circuit board signal trace.
d.
Use a minimal amount of solder between the contact pin and signal trace. Do not allow excess solder to build up
or ?ow down the trace.
e. Clean all excess ?ux and other residue from the launch area, especially between the trace and ground
The basic steps required to mount the end launch connector to the circuit board are as follows:
1.
Fixture 140-0000-973 should be used as an aid during manual soldering.
The ?xture protects the connector from damage during clamping and also
maintains the proper location of the connector’s insulator and contact. To
use the ?xture, 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
Figure 1
similar clamping device, as shown in Figure 1.
2.
3.
Position connector on the circuit board, making sure the contact pin is
aligned with the center of the signal trace as shown in Figure 2. Make sure
that the connector legs and contact pin are held ?ush 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.
A small amount of Te?on? insulation projects from rear mating plane of the
Figure 2
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.
Figure 3
4. While ensuring the connector is held in the correct position, solder the
ground legs and/or ground posts to the top and bottom of the board prior to
bonding the center pin to the trace.
Figure 4
Figure 5
5.
6.
Once the connector body is properly grounded to the board, the center
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 ?ows 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.
Clean all ?ux and other residues from the trace area between the signal
side ground legs, as any ?ux present between the signal trace and ground
will affect performance. The completed mounting assembly should look
similar to the one shown in Figure 5.
