B Noise from Contacts
Noise may be transmitted to the electronic circuit when switching a
load, such as a motor or transistor, that generates a surge at the
contacts. When designing patterns, take the following three points
into consideration.
1. Do not place a signal transmission pattern near the contact
2. Shorten the length of patterns that may be sources of noise.
3. Block noise from electronic circuits by means such as
C High-frequency Patterns
As the manipulated frequency is increased, pattern mutual
interference also increases. Therefore, take noise countermeasures
into consideration when designing high-frequency pattern and land
shapes.
G-6 Shape of Lands
1. The land section should be on the center line of the copper-foil
2. A break in the circular land area will prevent molten solder from
G-7 Pattern Conductor Width and Thickness
The following thicknesses of copper foil are standard: 35 μm and
70 μm. The conductor width is determined by the current flow and
allowable temperature rise. Refer to the chart below as a simple
guideline.

G-8 Conductor Pitch
The conductor pitch on a PCB is determined by the insulation
characteristics between conductors and the environmental
conditions under which the PCB is to be used. Refer to the following
graph. If the PCB must conform to safety organization standards
(such as UL, CSA, or IEC), however, priority must be given to
fulfilling their requirements. Also, multi-layer PCBs can be used as a
means of increasing the conductor pitch.

G-9 Securing the PCB
Although the PCB itself is not normally a source of vibration or shock,
it may prolong vibration or shock by resonating with external vibration
or shock. Securely fix the PCB, paying attention to the following
points.
