Panel Requirements for Assembly

Panel Requirements for Assembly

Panelization makes the process of PCB fabrication more efficient, and it saves on labor costs. In this manufacturing technique, small PCBs are manufactured and connected as a single array, which makes it easier to move through an assembly line. The individual panels can be depanelized and removed from the array for installation and packaging. The entire process is beneficial when you have a PCB that is smaller than what can be mass-produced and it saves money due to the reduced labor costs.

Panel Requirements for PCB Assembly

We can create paneled PCBs using your design, or we can help make a design using your single PCB file. There are many different ways to depanelize them, and how you do it will depend on what method you use to connect them. The primary methods include the following:

  • V-Grooves: Also called v-scoring, when you use this method, you trace a v-shaped cut on the top and bottom edge of the panel. These boards are normally scored at 1/3 the thickness. You will use a machine or a fixture to depanel it.
  • Tabs: This method connects individual circuits to the panel frame with tabs or breaking holes that can be snapped to separate the individual PCBs.
  • Both V-Grooves and Tabs: Some panels are made using both methods.

Fiducial Marks and Mounting Holes in Panels

Each panel requires a minimum of three fiducial marks. They are placed in the center of the tooling strips and have a diameter of 1.0 mm. The fiducial marks on the left need to be 10.0 mm away from the edge of the board, and those on the right should be 15.0 mm away from the edge.

The mounting holes should be set at 3.0 mm, and the width of the tooling strips need to be 7.0 mm. The mounting holes should be at least 5.0 mm from the edge of the board.

Methods of Depanelization

There are different methods for depaneling the PCBs. Take a look at the following:

  • Manual: The panels are manually separated. This is the most labor-intensive method.
  • Punch or die cutting: Use a fixture with a die cutter to punch the boards out of the panel.
  • Saw cut: You can line a saw blade up with the v-grooves to cut the individual panels out.
  • Depaneling router: This device is similar to a wood router, and it cuts the boards out of the panel.
  • Laser cutting: This device is also called a laser router, and the process can be automated to cut the panels out.

Our Experience

At MKTPCB, we have more than a decade of experience fabricating and assembling PCBs. We fabricate all types of PCBs using many different materials, and we can fabricate PCB panels. We take pride in our ability to complete the entire process in one location, and our highly qualified staff and engineers pay attention to every detail. We perform inspections throughout the process to ensure that all PCBs are high quality and functional.
