Impedance PCB Single End Impedance Controlled Circuit Board 6 Layer
PCB for Vehicle Tracking System
1.1 General description
This is a type of single end impedance controlled PCB built on FR-4
substrate with Tg 150°C for the application of vehicle tracking
system. As request, it's panelized 12 up with 10mm strips each
board because there's parts that overhangs the board. Addtional
breakout are added in line with the board, which makes it a lot
easier to remove the boards from the panels after assembly. It's an
impedance controlled board with 60 ohm on 6 mil single end track on
signal layer 3 and layer 4. Other specifications are 1.60 mm thick
with white silkscreen on both sides, green solder mask on both
sides and immersion gold are on pads. The base material substrate
is from ITEQ IT-158. They're fabricated per IPC 6012 Class 2 using
supplied Gerber data. Each 25 panels are packed for shipment.
1.2 Features and benefits
RoHS Compliance and conformity to IPC1401/126;
Industrial standard material with high Tg (175℃ by DSC) and
excellent thermal reliability;
SMT process is resistant to reflow soldering, resistant to rework;
High solderability, no stressing of circuit boards and less
contamination of PCB surface;

1.5 Impedance printed circuit board
Definition of Characteristic Impedance
At a certain frequency, relative to a reference layer, the
resistance of its high-frequency signals or electromagnetic waves
in the process of transmission is called the characteristic
impedance, which is the vector summation of electrical impedance,
inductive reactance, capacitance resistance.
The classification of characteristic impedance
Common characteristic impedance is divided into: (1) Single ended
(line) impedance; (2) Differential impedance and (3) coplanar
impedance, etc.
Single ended impedance refers to the measured impedance of a single
signal line. Differential impedance refers to the impedance
measured between the two transmission lines with equivalent width
and spacing in differential drive. Coplanar impedance refers to the
impedance measured when the signal line is transmitting between its
surrounding GND / VCC (the space between the signal line to GND /
VCC on both sides is equal).
The Determinant Condition Required for Impedance Control
When the signal is transmitted in the PCB conductor, if the length
of conductor is close to the 1/7 of the signal wavelength, then the
conductor at this time becomes a signal transmission line, the
other general signal transmission lines are required to be done
with impedance control. Whether it is required to control the
impedance in PCB production is based on the customer's requirement,
if the customer requires that a certain line width need to be done
with impedance control, it is required to control the impedance of
the line width in production.Three basic elements of impedance
match are the output impedance (the original active parts), the
characteristic impedance (signal line), the input impedance
(passive parts) (PCB board)
