Precautions
CORRECT USE
•
The following graph shows this relationship.
Seal integrity during cleaning will last for 1 minute at 70°C.
•
It is advantageous to use the Micro Strip Line in highfrequency transmission circuits because a low-loss transmission can be achieved with this method. By etching the
dielectric base which has copper foil attached to both sides,
the Micro Strip Line will have a concentrated electric field
between the lines and ground, as shown in the following
diagram.

(dielectric constant: εr)
•
•
The characteristic impedance of the lines ZO is determined
by the kind of base (dielectric constant), the base’s thickness,
and the width of the lines, as expressed in the following
equation.
=
ε W: Line width
Dielectric constant (εr)
+ π
+ π
εr: Effective dielectric constant
H: Dielectric base thickness
The copper foil thickness must be less than H.
•
For example, when creating 50-Ω lines using a glass epoxy
base with a thickness of 1.6 mm, the above graph will yield a
w/h ratio of 1.7 for a dielectric constant of 4.8. Since the base
thickness is 1.6 mm, the width will be h × 1.7 ≈ 2.7 mm.
The thickness of the copper foil “t” is ignored in this design
method, but it must be considered because large errors will
occur in extreme cases such as a foil thickness of t ≈ w.
In addition, with the Micro Strip Line design, the lines are too
short for the G6Y’s intended frequency bandwidths, so we
can ignore conductive losses and the line’s attenuation
constant.
The spacing of the Strip Lines and ground pattern should be
comparable to the width of the Strip Lines.

•
Design the pattern with the shortest possible distances.
Excessive distances will adversely effect the high-frequency
characteristics.
Spread the ground patterns as widely as possible so that
potential differences are unlikely to develop between the
ground patterns.
To avoid potential short-circuits, do not place the pattern’s
leads near the point where the bottom of the Relay attaches
to the board.

When the lines must curve, an elbow can be used as shown in
the diagram. A distance (D) between the lines of approximately
twice the line width is sufficient.
EXAMPLES OF MOUNTING DESIGNS
Using a Single-sided Board
Since this example emphasizes reducing mounting costs,
expensive mounting methods, such as through-hole boards, are
not shown. If such methods are to be used, the characteristics
must be studied carefully, using the actual board configuration.
When a single-sided board is used, isolation characteristics of
only 60 dB to 70 dB at 200 MHz can be obtained. When high
frequency bands are to be used with a single-sided board, a
metal plate can be placed between the base and Relay and
connected to the ground pattern.
Using a Double-sided Paper Epoxy Board
When double-sided paper epoxy boards are used, the dielectric
constant will be approximately the same as that of glass epoxy
boards (εr=4.8).
Metal plate
The width of the Strip Lines for a board with t=1.6 mm is 2.7 mm
for 50 Ω and 1.8 mm for 75 Ω. For a board with t=1.0 mm the
width is 1.7 mm for 50 Ω and 0.8 mm for 75 Ω.
The following diagram shows an example pattern, and the Micro
Strip Lines connected to the contact terminals are formed with
pattern widths derived from the description above. The width
between the Micro Strip Lines and ground patterns are
comparable to the Micro Strip Line width.
There are jumpers between the upper and lower patterns at the
points marked with Xs in the diagram. Improved characteristics
can be obtained with more jumper locations. This method yields
isolation characteristics of 65 dB to 75 dB at 500 MHz and 50 dB
at 900 MHz.
At this point in the diagram the component side is the entire
ground pattern side; but, you must set aside approximately
2.0 mm × 2.0 mm of the pattern for the contact terminals and
coil terminals.

Pattern
With this method a metal plate is placed between the Relay and
base and connected to the pattern, as shown in the above
diagram. The important point here is that 3 locations (the G6Y’s
ground terminal, the metal plate’s bent tabs (A), and the ground
pattern) are soldered together at the same time. This method
combines an inexpensive single-sided board and inexpensive
metal plate to yield the same characteristics as a double-sided
board. Good characteristics are obtained by grounding the G6Y’s
ground terminal and metal plate in the same place.
The metal plate must be attached to the base as described here.
From this point, the methods used for Strip Line design are the
same as for the double-sided board.

Mounting Precautions
Be sure to securely attach the Relay’s base surface to the board
during installation. The isolation characteristics will be affected if
the Relay lifts off the board.
As shown in the enlarged illustration of the cross-section of part
A, the G6Y is designed to ensure better high-frequency
characteristics if the stand-off part of the G6Y is in contact with
the ground pattern of the PCB. For this reason, the ground
terminal and stand-off part are electrically connected internally.
For example, if the terminal hole on the PCB is 1 mm in diameter
and the length B shown in the illustration is 1.4 mm, a distance of
0.3 mm or more will be provided between the through hole and
stand-off part.
PCB Mounting
Should the through hole electrically connected to the contact
terminal come in contact with the stand-off part, the contact will
be short-circuited with the ground, which may cause an accident.
As a preventive measure, keep at least a distance of 0.3 mm
between the stand-off part and the through hole or land.
