Hello All, I was given an assembled flex circuit PCB and asked how the board was depanelized as there are no view-able witness marks that I can see. Any ideas? Thanks in advance on any insight to depanelizing without leaving witness marks on the F

Don't rule out the possibility that the board shop depanelized it and it was assembled after depanelization. Been there, dealt with it, expletives deleted.

Common methods used for depaneling flexible circuits are: * Laser * Punching * Water jet

Several methods are available for singulating or extricating individual flexible circuits from a processed panel; this discussion of the topic applies to all types of flexible circuits. In general, the methods for singulating flex circuits can be bra

Lasers can be used to depanel individual PCBs from panels. In addition, laser depaneling is often used when very tight tolerances are required for PCBs such as when there is very little room in an enclosure that the board is fitting in to. But the ch

Local customer is looking for ways to depanelize very small flexible circuits after assembly. Perhaps shearing as opposed to a router would make sense. Any recommendations on manufacturers for such technology? Volume is around 100,000 pieces per mont

Thanks Dave .........can anyone recommend any vendors for water jetting or punching?

if you have a budget for new machine, laser depanelising is pretty good for flex PCB as no physical stress on PCB like mechanical routing, thus fixturing is easier and less prone to moving the flex while cutting. Laser systens can also cut FR4 standa

If your flex circuit is only populated on one side, you can have the PCB vendor palletize the flex for you. What you do is have the flex circuit laminated to 062" FR4 using a thermoset adhesive like Dupont WA. Standard flex circuit adhesive. Howev
