The separation between the strip line and each ground pattern
should be approximately the same as the strip line width.
• Conductive patterns should be designed to be as short as
• Each ground pattern should be designed to be as wide as
• Avoid directing of conductive lines in the area of the PC
Since these examples are presented with an eye to low cost
packaging, expensive packaging methods, such as thru-hole
connection, are not described. For this reason, the
characteristics of each circuit board should be checked
thoroughly before putting it to practical use.
The method of packaging using paper epoxy type double-
sided PC board.
The dielectric constant of a paper epoxy type double-sided PC
board is considered to be approximately the same as that of a
glass epoxy type PC board

The width of a strip transmission line is as follows:
Unit mm (inch)
The figure above shows the conductive pattern side. The
microstrip connected to the contact terminal must be of the
above-mentioned pattern width. Ensure that the distance
between microstrip and each ground pattern is approximately
the same as the width of the microstrip. Connect with jumpers
between the top and bottom of the pattern at the points
marked “X” in the figure. The greater the number of jumper
points, the better the high-frequency characteristics. In this
manner, an isolation of 65 to 75 dB at 500 MHz or 50 dB at
900 MHz can be obtained. In this case, the components
mounting side of the PC board is entirely the ground pattern.

The method of packaging using a single-sided PC board
When a relay is mounted on a single-sided PC board, an
isolation of only 60 to 70 dB can be obtained at 200 MHz.
Therefore, to permit the relay on the single-sided PC board in
a higher frequency range, a metallic plate can be inserted
between the PC board and the relay, then connected to the
ground pattern.
As seen in the figure to the left, a metallic plate is sandwiched
between the relay and the PC board to connect to the pattern.
The key is that the ground terminal of the Type G5Y-1 relay,
the bent tabs A of the metallic plate, and the ground pattern
must be soldered together at one time.
This combination of a low-cost, single-sided PC board and a
low-cost, metallic plate, provides the same high-frequency
characteristics as when the relay is mounted on a double-
sided PC board.
By grounding the ground terminal of the Type G5Y-1 relay and
the metallic plate at the same place, excellent high-frequency
characteristics can be obtained.
In this method, the metallic plate must adhere firmly to the PC
board. The design of strip transmission lines should be the
same as when a double-sided PC board is employed.
Note: In the interest of product improvement, specifications
CAUTION:
A key point in mounting the relay on a single-sided PC
board is to ensure that the relay base is not floating
above the PC board or metallic plate, but bottoms
firmly upon them.
