Examples of Mounting Designs
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.
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).
The width of the Strip Lines for a board with t=1.6 mm is 2.7 mm for
50 Ω and 1.3 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 set aside approximately 2.0 mm × 2.0 mm of the
pattern for the contact terminals and coil terminals.

G6Y
The metal plate must be attached to the base as described here.
From this point, the methods used fowr Swtrwip.DLainteadSheseiegnt4aUr.ecothme 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. Therefore, the ground terminal and stand-off part are
electrically connected internally.
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.
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.

Using a Single-sided Board
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.

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.
