PCB News - How to calculate the area of a circuit board

When making PCB boards,many PCB manufacturers will use the method of splicing boards to make full use of the boards, thereby reducing production costs. How to calculate the area of the circuit board, this can only be calculated after it is fixed, otherwise it cannot be calculated. Today, the editor will introduce the formula for calculating the area of the PWB board.

We use 1 square meter = 1000000MM, and now the number of panels is 114mm*105.2mm*12PCS to calculate how many PCS will be produced per square meter. The calculation is divided into two cases: with edge and without half edge.

In the absence of board edges, the total amount of one square meter = 1000000÷(114*105.2);
In the case of board edges, the total amount of one square meter [1000000÷(114*105.2*12+ board edge area)]*12.
One square/single size = quantity For example, a single size of 10*10cm, one square = 10000cm2 and then divide by 100cm2=100pcs.
Use 1000mm*1000mm plate to calculate;
1000/114=8.77, rounded to 8; the remaining 0.77 cannot produce an imposition;
1000/105.2=9.505, rounded to 9; the rest is also scrap;
Then the number of impositions that can be produced: 8*9=72 impositions;
Can produce finished products: 72*12pcs=864 pcs.
