FAQ:
Q1: What are PCB Mouse bites?
A1:
Mouse bites also known as perforated breakaway tabs in a PCB are small perforations / pricks on the board which allow for panelizing and depanelizing smaller groups of PCBs together. This way multiple PCB boards can be assembled together, thereby saving time and making the process cost-effective. The assembled PCBs can be separated by applying pressure on the sections of the board that have perforations. Once separated, i.e after the depanelization process, the board looks like it has mouse bites in these sections.
Below is an Image of PCBs assembled to each other with the help of mouse bites.
Below is an Image of a PCB being depaneled easily which is also made possible due to mouse bites. You can also see the sharp edges after the boards have been separated, these are called mouse bites.
When multiple PCBs are connected using mouse bites they have a smooth finish. When compared to PCB boards connected using V-Scoring, boards connected with mouse bites are easier to depanelize i.e they require less force.
Precautions to take before inserting Mouse bites on a PCB
