NOTE)
The DSP P.C.B. actually has a four-layer pattern structure (part face pattern, internal pattern
1, internal pattern 2 and solder face pattern) but it is shown as "part face pattern + solder
face pattern" in this diagram.
NOTE)
DSP P.C.B.は、4層パターン構造（部品面パターン、内層1パターン、内層2パターン、ハンダ面パ
ターン）ですが、本図のDSP P.C.B.は、部品面パターン＋ハンダ面パターンを表記しております。
