6-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• : Through hole.

Printed wiring board of BD board is shown only for refer-
ring, because CD base unit is replaced as a block.
• SUB boards is four-layer pritnted board.
However, the patterns of layer 2 and 3 have not been included in
this diagrams.
* Replacement of IC101 and IC401 used in this set requires a
special tool.

conventional IC
* Replacement of IC101 and IC401 used in this set requires a

• The voltage and waveform of CSP (chip size package) cannot be
measured, because its lead layout is different from that of
conventional IC.
