Minimising mechanical stresses on Printed Circuit Boards (PCB) with a depaneling router


Circuitwise is thrilled to announce a significant upgrade to our production capabilities with the installation of an advanced Automated PCB Depaneling Router. This cutting-edge technology is a game changer for improving the smoothness and mechanical integrity of the finished PCB, while delivering unparalleled precision and efficiency.


Depaneling is the process by which individual PCB assemblies are removed from a panel coming off the production line. Traditionally, removing PCBs from panels is a manual process, relying on mouse bites or V-grooves, that can result in rough edges and compromised board integrity. Protruding edges at the snap off point can make fitting the PCB into highly constrained enclosures difficult.


Our new router eliminates these issues, ensuring that every PCB emerges with a flawless finish. Using a router bit to mill the material ensures a precise edge for the PCB, giving designers the confidence to use all space right to the board's edge. In addition, routing avoids mechanical stresses on the PCB lamination and components, otherwise caused by the PCB being snapped out of the panel.

Our new router is a versatile tool, capable of handling a wide range of PCB sizes, and is particularly helpful for small odd-shaped boards designed for constrained spaces.


The machine is equipped with a dual high-speed camera auxiliary programming system, making programming easier. A high-speed CCD vision automatic correction system greatly improves the cutting accuracy and operation efficiency. A high-speed spindle delivers low splitting stress and high precision, and it is suitable for any shape of circuit board. The machine has dual-table movement so it can cut two different products and place the circuit board at the same time, improving efficiency.


Circuitwise is proud to invest in state-of-the-art technology to provide our customers with the best possible service.

This equipment was purchased with the support of a Supply Chain Resilience grant from the Australian government.
