The following data is input in advance.

(1) Standard fixed-price price depending on the usage conditions of the printed circuit board material Item Number of layers Small diameter presence / absence Pin density Glass epoxy Paper epoxy Paper phenol 14 Yes 3 pcs. \ 80,000--24 No 3 pcs. 4 No 1 or 2 \ 65,000--4 2 Yes 3 \ 50,000--5 2 No 3 \ 45,000--6 2 No 1 or 2 \ 43,000--7 2 No 1-41,000 8 Single side- 0 books-\ 10,000

The standard fixed-price price may be arbitrarily input each time without using the stored price.

(2) Number of pieces of work size from fixed-size printed circuit board material Item Size (mm) Number of pieces of work size from fixed-size printed circuit board material Normal size Jumbo size 1 610 * 510 3.3 sheets / square meter 4 Sheets / 1.2 square rice 2 510 * 406 5 sheets / square rice 6 sheets / 1.2 square rice 3 340 * 340 9 sheets / square rice -4 610 * 340 5 sheets / square rice 6 sheets / 1.2 square Rice 5 510 * 340 6 sheets / square rice -6 340 * 255 12 sheets / square rice -7 510 * 510 4 sheets / square rice -8 460 * 340 7.5 sheets / square rice 6 sheets / 1.2 square rice

(3) Landing dimensions (gap size: see FIG. 2)

A and B shown in FIG. 2 represent the minimum size of the printed circuit board in the manufacturing process including the size of the final printed circuit board and the size of a margin required for a plus operation (such as a margin). Yes, by getting the size efficiently, it approaches the work size as much as possible.

In the example shown in FIG. 2, a printed board of a final size, that is, two printed boards (shaded display portions) to be taken out is included.

The ground size differs depending on the maker of the printed circuit board material. Therefore, the ground size for each maker is input by the input device 1 and stored in the storage device 2 as follows.

Item abw 1 General dimensions 10 10 5 2 G company 15 10 5 3 H company 15 155

Further, the ground size may be arbitrarily input each time without using the stored size data.

(4) Calculation formulas for calculating the work size including the ground removal dimensions The vertical size (A) and the horizontal size (B) of the work size are respectively obtained by the following formulas, and these formulas are input. The data is input by the device 1 and stored in the storage device 2.

Vertical size: mX + 2a + (m-1) w ≦ A Horizontal size: nY + 2b + (n−1) w ≦ B

Calculate by substituting each work size and each work size into the above formula, and calculate the number of work (m) in the horizontal direction and the work size in the vertical direction for the vertical size (A) and horizontal size (B) of the work size. When the value of the number (n) is closest to [1.0], the efficiency of removing the printed circuit board is good.

mm, a = 15 mm, b = 15 mm, w = 5 mm, 320 m + 2 × 15 + (m−1) × 5 ≦ A (horizontal) 325 m ≦ A−25 → m ≦ A−25 / 325 ↓ m = 1 A = 350 320n + 2 × 15 + (n−1) × 5 ≦ B (vertical) 325n ≦ B−25 → n ≦ B−25 / 325 ↓ Assuming that the number is closest to n = 1, B = 350 A * B = 350 * 350 The work size that clears this current dimension is ↓ 510 * 406 (optimum work size)

Since 510 * 406 is the optimum work size, the number of pieces of the work size obtained from the fixed-size printed circuit board material having the jumbo size is determined by the above-described “(2) Fixed-size printed circuit board material” stored in the storage device 2.
