Microstrip board

Micro stripline

The three types of mounting methods

illustrated in the diagrams below will

mount the card coupler for use under

optimum conditions.

The fastening screws in the diagrams

are M2 screws tightened to 1.5 kg • cm.

When the tip of the micro stripline is of

Teflon type material ( r = 2.6), C

chamfering of C1 is performed at t1.6,

and of C0.5 at t1.2.

The side view diagrams of Figure 1 are

illustrated in Figures 2, 3, and 4 below.

Gap S between the card coupler and

the microstrip board surface should be

used to agree with the following

conditions.

( Below 500 MHz ........S≤0.5 mm

500 to 2300 MHz......S≤0.25 mm

Above 2300 MHz......S≤0.15 mm

Metal plate or conductive spacer

qWhen the Ground Board is Constructed of 0.4 mm Stainless and 0.8 mm Aluminum

(When the Thickness of the Microstrip Board is 1.6 or 1.2 mm)

For t1.6 boards, use with the stainless case of the card coupler facing upward. For t1.2 boards,

use with the aluminum case of the card coupler facing upward. Mount and fix the card coupler

with fastening screws as illustrated in Figure 2. Next, solder the tabs and micro stripline, then

use.

(When the Thickness of the Microstrip Board is Greater than 1.6 mm)

Insert a metal plate or a conductive spacer between the coupler and ground, then mount as

illustrated in Figure 3 so that the surface of the tabs and the position of the microstrip board are

equal. Fix the card coupler with fastening screws as illustrated in Figure 3. Next, solder the tabs

and micro stripline, then use.

(When the Thickness of the Microstrip Board is Less than 1.2 mm)

Cut the ground at the position of the coupler and attach so that the surface of the tabs is in

contact with the micro stripline. Fix the card coupler with fastening screws as illustrated in Figure

4. Next, solder the tabs and micro stripline, then use.
