Do PCB Designs Require Reserving Board Edges and Grooves for Routers De-Paneling Machines?

A while back, a netizen asked how the Router de-panel machine cuts PCB panels and whether there’s a need to reserve board edges (break-away) for the Router machine in PCB design. Upon careful consideration, I thought my previous answer might … Continue reading

PCB Board Edge Removal and Panelization: Pros and Cons of Router Panel Cutting

There are several methods to cut and separate pre-panelized PCBs into individual boards, and one commonly adopted approach for thin and finely dimensioned mobile phone PCBs is using a Router Cutting Machine. It offers numerous advantages over V-Cut scoring machines, … Continue reading

PCB De-Paneling: V-cut scoring de-paneling and removing board edges

The term “V-cut” refers to a pre-cut separation groove made by printed circuit board (PCB) manufacturers at specific locations on the PCB. This groove is designed to facilitate the “de-paneling” process after the completion of surface mount technology (SMT)  and … Continue reading

What is V-cut? Why PCB need to design V-cut on it?

The term “V-cut” in the context of printed circuit boards (PCBs) refers to predefined cutting lines made by PCB manufacturers based on customer drawings. These lines are typically arranged in a V-shaped pattern, resembling the letter “V,” which is why … Continue reading

Why is Panelization and Break-away Tab Necessary in PCB Manufacturing, then De-paneling after PCBA is Completed?

Why is “Panelization” performed during PCB manufacturing? And after surface mounting (SMT) assembly and wave soldering, why is it necessary to go through the additional process of “de-paneling” to separate the individual boards? What is the purpose of the PCB’s … Continue reading
