Let us show you the introduction example of "High-Frequency
Printed Circuit Board" processed by the
MITS Prototyping board making machine, thanks to the special collaboration
with Dr.Kouji Wada
at The University of Electro-Communications.
The Advantages of using MITS Prototyping
Board Making Machine
- You can easily acquire the technical knowledge for producing
a PCB, and can process a high-accuracy printed circuit
board within a short period of time. As you don't use
any chemical agents with our machines, you don't have
to be anxious about the troublesome waste liquid treatment.
- By using the data obtained from the results of simulating
experiments, such as electromagnetic field simulation,
you can effectively produce the high-frequency PCB.
- Based on the comparison between the simulation results
and that of assays on the PCB, you can immediately apply
that data on the improvement of the actual PCB pattern-designing.

Let us illustrate the procedure of PCB processing beginning from
the pattern-designing to
the data evaluation, by taking the case of the high-frequency filter
(dual-band filter with
micro-strip line) as an example
| At the preliminary step towards designing the
print circuit pattern by PCB processing machine, we calculate
the structural parameter of the filter by the computer program,
and evaluate the characteristics of the electric transmission. |

electric transmission characteristics by the circuit simulator
in the light of the result of designing the dual-band-filter
using the microstrip substrate. |

| We can also calculate the distribution of the
electric current density, as well as the characteristics of
the electric transmission, by analyzing the pattern shape
of trial circuit using structural simulators such as the electromagnetic
field simulator. |

We are able to grasp and visualize the electromagnetic
distribution by the structural simulator. Also, we can make
use of that data for the designing of the circuit board.

Based on the data acquired by the result of the designing, simulation,
and by the analysis,
we produce the circuit board using the PCB processing machine. Next,
we estimate the
circuit board that we produced and evaluate the characteristics
of them by comparing
the result of the simulation and analysis.
