Claims

[Scope of utility model registration request]

A dot pattern 2' consisting of perfectly circular rounds 2a having a rectangular shape and a large number of through holes arranged at equal intervals in the longitudinal direction and the width direction is formed, and in the dot pattern 2', a perfectly circular dot pattern 2a is formed. Rounds 2b, 2b having a desired shape and having through-holes for taking out the pattern of the double layer 4 are placed in a row of perfectly circular rounds 2a' located at positions that divide the row of rounds 2a into several equal parts in the longitudinal direction. Rounds 2c of a desired shape are provided to sandwich the circular rounds 2a, and have through holes for taking out the three-layer pattern 5 in rows of perfect circular rounds 2a'' located at positions dividing the width into several equal parts. , 2c are provided between the perfectly circular rounds 2a, and further, outside the dot pattern 2', adjacent perfectly circular rounds 2a are provided on the sides of the dot pattern 2' at equal intervals to and adjacent to the perfectly circular rounds 2a. A round 2b' having a desired shape, which has a through hole located between the rounds 2a, 2a and connecting the round at the end of the pattern of the two-layer 4, which connects the middle round to the round 2b, 2b having the desired shape. 2b' are provided above and below the dot pattern 2' at equal intervals to the perfectly circular rounds 2a and between the adjacent perfectly circular rounds 2a, 2a, and the desired shaped rounds are provided. The first layer 2 and the fourth layer 3 are provided with rounds 2c' and 2c' of a desired shape, each having a through hole connecting the round at the end of the pattern of the three layer 5, which connects the round at the middle part to the rounds 2c and 2c, and the first layer 3. Rounds 4a, 4a having through holes in the middle part are connected to the rounds 2b, 2b of the desired shape, which are sandwiched between the rounds 2b, 2b and the four layers 3, and the rounds 4a, 4a have through holes in both ends.
a', 4a' into the desired shape of the round 2b',
2b', a double layer 4 formed with line patterns 4b, 4b extending in the longitudinal direction between the perfectly circular rounds 2a, 2a in the dot pattern 2', and an intermediate layer 4 formed between the rounds 2c, 2c having the desired shape. A round 5 having through holes at both ends connects the rounds 5a, 5a having through holes at both ends.
a', 5a' into the desired shape round 2c',
2c', and a three-layer printed circuit board 5 formed with line patterns 5b, 5b extending in the width direction between the perfect circular rounds 2a, 2a in the dot pattern 2'.
