Conductor width and microstrip
Patterns for DC circuits
The following thicknesses of copper foil are standard: 35 m
(1.38 mil) and 70 m (2.76 mil). The conductor width is
determined by the carry current and allowable temperature
rise. Refer to the table on the following page.
Conductor width and carry current
(according to IEC Pub321)
For high-frequency transmission circuits, the use of
microstrips is recommended. By adopting this stripline
method, a low-loss transmission circuit can be configured. The
microstrips are prepared by etching a PC board made of
dielectric material and covered on both sides with copper foil.
As shown in the figure below, the microstrip utilizes the
concentration of the electric field between transmission line
and the ground.
foil pattern so that the soldered fillets become uniform.
manually after the automatic soldering of the PC board, a
terminal hole can be secured by providing a break in the
land.
MICROSTRIPS
The characteristic impedance of a transmission line is
determined by the type of PC board (specific inductive
capacity), its thickness, and the width of the transmission line.
This impedance is expressed by the following formula.
where
w: Width of transmission line
e
h: Thickness of dielectric PC board, provided that the
This relationship is shown the the figure below.
For example, when a 50
using a 1.6 mm (0.06) glass epoxy type double-sided PC
board, the width of the transmission line can be obtained in
the following manner. Since the specific inductive capacity (
of this circuit board is 4.8, w/h = 1.7 (obtained from the above
table). Based on the thickness of the PC board (e.g., 1.6 mm
[0.06]), the thickness of transmission line w can be calculated
as follows.
w = h x 1.7 = 1.6 (0.06) x 1.7
Note that in this calculation, the thickness of copper foil “t” is
ignored, so there may be a greater error in characteristic
impedance of t
transmission line, due to the effective filling rate of microstrip
or dielectric loss and conductor loss, is not taken into account,
but these factors must be considered in the actual design of
microstrips. In the frequency band for which Model G5Y is
intended, however, these factors may be ignored by
shortening the length of the transmission line.
