5 Important Points When Panelizing PCBs

Dated:2017-04-07      Popularity:1261

When it comes to panelizing PCBs - the art of joining up the individual ‘circuits’ to make a ‘panel’ - less care and attention are paid on it. Ignoring some of the delicate details associated with board penalization could end up costing you. So when it comes to PCB penalization, 5 points you should keep in mind: 

Cross outs are not allowed as they can cause lots of headaches. So you must inform your bare board supplier that cross outs not acceptable.

If PCBs are separated by scoring instead of routing, pads and traces must be at least 5mm away from the edges of the score line, to allow them to be cut from their panel.

If the board has scribing on, it should be equal from both sides, giving a 0.4mm with a tolerance of ±20% about the centre line. Extended wastage on the short edge should be added to allow jump scribing.

Proper pips are used for routed PCBs. PCBs should be partially routed using a 2.4 mm -0/+0.1mm diameter cutter and supported by 2.5mm pips, placed between 10mm and 15mm from each corner. Further support pips should not be less than 25mm, and no more than 100 mm apart, except where this may interfere with component assemblies that extend beyond the board profile. There must be a minimum gap of a 20mm on, at least, one side of every pip.

Finally, before quoting, there’s some additional information that you will need to provide. For example, what is the required material, thickness, finish, solder resist color, silk screen color, copper weight, etc? Clearly stated before the quotation is really matters, because it can save you time and money further down the production line.
