When making imposition, you can easily separate multiple boards to avoid damage to the circuit board during the separation. Determine which type of board to use according to the shape of a single type of your imposition. PCB imposition methods mainly include V-CUT, punching, and stamp hole. The following is a brief introduction to these imposition methods:
1. PCB assembly method—V-CUT
V-CUT means that several boards or the same board can be combined and spliced together, and then after the PCB processing is completed, a V-cut machine is used to cut a V-shaped groove between the boards, which can be broken during use. It is the more popular way nowadays.
2. PCB assembly method-punching groove
Punching refers to milling out between the board or the inside of the board with a milling machine as needed, which is equivalent to digging out.
3. PCB jigsaw method—stamp hole
The so-called stamp use is to use a small hole to link the board to the board, which looks like the zigzag on the stamp, so it is called the stamp hole link. The stamp hole link requires high-control burrs on all four sides between the board and the board, that is, only a small stamp hole can be used to replace the V line.
