The Methods of Panelizing PCBs

There are different methods for making panelized PCBs, and each is unique. Although the PCB breakaway design and V-scoring are the most outstanding, there are a couple of others.

Here is a breakdown of how each of the circuit board panelization methods work:

1. Tab Routing

Also called the PCB breakaway tabs, they refer to the pre-cutting of the circuit boards from the array. It is then followed up by the use of perforated tabs to hold the PCBs onto the circuit board.

2. V-Scoring

This is another circuit board panelization process. It involves the making of grooves via cutting off from the top and bottom of the PCB, a one-third thickness of the circuit board.

An angled blade is usually used for this process and the remaining third of the PCB is often smoothened out with the help of a machine.

3. Die Cutting

This is the third type of PCB panelization. It entails the punching out of individual PCBs from a panel, with the help of a fixture with die cutter.

4. Solid Tab Panelization for PCBs

It is better to use a laser-cutting machine for this process. It involves making solid tabs between the circuit boards, with the aim of strengthening the bond.

5. Laser Router

Also called the laser-cut PCB panelization method, it involves the automated process of carving or making out any shape from the circuit boards.

In addition to reducing the mechanical stresses that potentially come with the process, laser router also comes in handy when panelizing the PCBs with either unusual shapes or tighter tolerances.
