How to improve the use ratio of PCB Board

1. Enlarge the PCB panel size, the larger panel, the less margin wasted;
2. Increase the pieces of PCB Board in each Sheet, which could also decrease the margin waste;
3. If two types of PCB such as A(big) and B(small), they could not reach a good use ratio when arrayed separately, then you could consider whether is suitable to array A and B in one sheet;
4. It is great to use professional software to arrange the PCB Board array.
