PRINTED  WIRING  BOARDS
Note on Printed Wiring Boards:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
f
: internal component.
•
b
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Conductor Side)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Component Side)
the parts face are indicated.
• MAIN board is multi-layer printed board.
However, the patterns of intermediate-layer have not been
included in the diagram.
