The first is the problem of panel. We know that the main problem of panelis to save the cost of production. The width of PCB panel ≤ 260mm ~ 300mmvaries according to different production lines. Because we may have manymaterials, and one material gun of our processing equipment corresponds to onemodule, if the panel exceeds the scope of the module, the processing speed willbecome very slow.

The outer frame (clamping edge) of the PCB panel shall be carefullyconsidered to ensure that the PCB panel will not deform after being fixed onthe fixture (generally, V-slot is not allowed on this edge). For the layout ofcomponents, first, all orientations shall be consistent, and there shall be nomirror image, which will cause the problem of coordinate positioning ofprocessing.

Second, there can be no connector protruding at the edge (between the outerframe of the panel and the inner panel, between the panel and the panel). Ifthis situation exists, it will hinder the tool plate splitting after welding.

In order to ensure the position and level of the detection plate, we needto set more than three positioning points on the edge of the plate. Throughoptical detection of these three points, we can get the reference coordinatesof the whole processing and the levelness of the plate.

The correct approach is that when the distance is 5mm from the edge and thetravel direction is inconsistent, the spacing is different (it is convenient todistinguish the entry direction): [when setting the reference positioningpoint, generally leave an unobstructed welding area 1.5mm larger than thepositioning point, and there can be no similar pad or other similar]

There shall be at least three positioning holes in each small plate, with 3≤ hole diameter ≤ 6 mm. Wiring or patch is not allowed within 1mm of the edgepositioning hole (to prevent misjudgment). PCB assembly is mainly to saveproduction and processing costs (which will make the machine processing speedseveral times faster). Unreasonable design will fill the later stage withproblems. You can take a closer look to prevent problems.
