Why is PCB Panelization Required before SMT?
When mass-producing SMT PCBA, in most cases there is a step of PCB panelization. Reasonable PCB panelization can improve production efficiency and save material costs.
What is PCB panelization?
According to the requirements of factory equipment, when performing smt patch components on PCB, the circuit board needs to be fixed on the fixture of the equipment under the specified size before processing. If the PCB is too small or irregular in shape, it cannot be fixed on the fixture of the smt equipment. In order to enable PCBs to be processed smoothly by smt, we will perform PCB panelization operations for small-sized and irregular PCBs, and put multiple PCBs through v-cut and stamp holes into a neat board to facilitate processing. This can also greatly improve the efficiency of smt patch and wave soldering.
What is V-cut, Stamp Hole?
V-cut panelization is to cut a V-shaped groove on the edge of the connection between two circuit boards, leaving a 0.4mm gap to facilitate subsequent manual separation of the boards. The v-cut method is suitable for use in relatively regular PCB boards.
Stamp hole panelization is to connect the edges of two boards through a small piece of board with many small holes. Because it looks like stamp holes, it is called stamp hole panelization. The stamp hole paneling method is suitable for use in irregular PCB boards, such as round PCBs, which is not possible with v-cut.
The use of PCB panelization during the mass production of SMT PCBA is a method to make small-sized and irregular PCBs conducive to smt processing, improve efficiency, and save materials.
