Note on Printed Wiring Boards:
D
• Y : parts extracted from the conductor side.
• : Through hole.
z
• 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
E
(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 four-layer printed board.
However, the patterns of layers 2 and 3 have not been in-
cluded in this diagrams.
