In order to improve PCB manufacturing and assembly efficiency, we recommend panel design for PCB manufacturing and assembly, panel will also reduce PCB manufacture and assembly cost in a way.

The best panel for assembly is from 50mm*50mm to 330mm*530mm. If your panel size is smaller or bigger, feel free to contact us for checking. And if you have Panel design drawing, feel free to provide it and we can follow it, or we can do the panel design according to your request, or we can do the panel drawing based on our production view.

1. Panel with V-CUT/V-GROOVE

We require 0.0mm spacing between each unit for panel with V-cut. Please note V-Cut line is just a line and no more space needed between the connected boards

And since the V-scoring line could only go through the whole board and no-stop, V-cut can only be a straight line and cannot be used for the panel with units of different sizes. Take the following panel for an example, we would recommend Tab-routing instead of V-cut.

2. Panel with TAB-ROUTE

For panel with Tab-route, we would need 2.0mm spacing between each unit. And we offer two options for tab-routing: Tab-Route with breaking holes and Tab-route with tabs.

• Tab-Route with breaking holes/stamp holes

For this kind of Tab-route, we require stamp holes diameter be between 0.3mm-1.0mm, spacing between the stamp holes be ≥0.25mm and stamp holes number in each tab be around 5-6. See the following picture for an example.

• Tab-route with tabs, the width of tabs should be 1.0mm.

3. Panel with both V-CUT and ROUTE Fiducial

For panel with both V-cut and Route fiducial, we require 2.0mm spacing between each unit. Please refer the following image to design the panel.

Fiducial marks and mounting holes in panel

1. Fiducial marks

For each panel, we require at least 3 fiducial marks. Those marks should be placed in the middle of the tooling strips with the diameter at 1.0mm.

The fiducial marks on board's left should be 10.0mm away from the board edge, and the right ones should be 15.0mm away from the board's right edge. See the following picture for your reference.

2. Mounting holes

We would recommend diameter of mounting holes to be set at 3.0mm and the width of tooling strips at 7.0mm, and at least 5.0mm distance from the edge of the board. Check the picture below for reference.
