Manufacturing of Original PCB


I will introduce about the making of the Printed Circuit Board(PCB)
which I use when I assemble the electronic circuits from this page.

The circuit board when I assemble the electronic circuits is generally using the one which is called "The universal circuit board".
As for the reason, the circuit to make is because it makes only once.
Generally, I don't make many sheet of the printed boards with the same pattern.
Also, when changing the circuit after the operation confirmation of the circuit, the universal circuit board is convenient.

However, when trying to make all electronic circuitses with the universal circuit board, there is a limit.
The case where had better make the Printed Circuit Board is shown below.
    The circuit which handles the high frequency
      In case of the circuit which handles the high frequency (the MHz order), the length of the wiring, the way of letting through the wiring have an influence on the circuit operation. Because it is, it is necessary to investigate the length of the wiring, the distance with the other circuit.

    When doing the high density assembly
      In case of the universal circuit board, the hole to mount the part becomes the 0.1-inch interval.
      Because it is, in the case which mounts with the part in the interval below it, the Printed Circuit Board must be made.

    When the lead line of the part is not the 0.1-inch interval
      For example, in case of the transformer for the high frequency, the lead line of the shielding case is not the 0.1-inch interval to the lead line of the coil.
      Because it is, when mounting such a coil on the universal circuit board, a hole for the lead line of the shielding case must be made in the circuit board.
      Or, it makes turn the 45 and it mounts.


To make the Printed Circuit Board, the implement is necessary and begins in the labor, the time, too. When complete in, there is that the affecting its original electronic circuits was composed of which is done.
By all means, challenge.
