PCB panelization skills [Copy link]

We know that the main problem of panelization is to save production costs. For PCB panelization width ≤260mm～300mm, it varies according to different production lines. Because we may have a lot of materials, and the processing equipment itself has one gun corresponding to one module, so if the panelization exceeds the range of the module, the processing speed will become very slow.

The outer frame (clamping edge) of the PCB panelization should be carefully considered to ensure that the PCB panelization will not be deformed after being fixed on the fixture (V-groove is generally not allowed on this edge).

For the arrangement of components, first, all directions should be consistent, and mirroring should not occur, which will cause problems in coordinate positioning during processing.

Second, there should be no connectors sticking out from the edges (between the outer frame of the panel and the internal small board, or between the small boards). If this happens, it will hinder the tool from separating the boards after welding is completed.

In order to ensure the position and level of the detection plate, we need to set more than three positioning points on the edge of the plate. By optically detecting these three points, we can get the reference coordinates of the entire processing and the levelness of the plate. , 73, 73)]

The correct approach is to use different spacings when the distances are 5mm from the edge and the directions of travel are inconsistent (to facilitate distinguishing the entry direction):

When setting the reference positioning point, usually leave a 1.5mm larger solder-free area around the positioning point. There should be no similar pads or other similar ones.]

There must be at least three positioning holes on each small board, 3≤aperture≤6 mm, wiring or patch is not allowed within 1mm of the edge positioning hole (to prevent misjudgment)

PCB paneling is mainly to save production and processing costs (it will make the machine processing speed several times faster). Unreasonable design will cause many problems in the later stage. You can take a closer look to prevent problems.

It's the first time to make a layout, let's check the information

I have a question that I don't understand. Isn't the process edge generally 5mm wide? The positioning point at the arrow should only refer to 5mm from the left and right edges, not counting the distance from the bottom.

Good stuff. For beginners, it is necessary to understand this. Only by mastering the basic knowledge can you go to the next level. I will come here often in the future.
