Need Help, How to create gerber for this PCB

(1/2) > >>

glicos:
I have a PCB for reverse engineering. Attachment 1 is the actual PCB and 2 is the 3D representation of the PCB. The problem i have is the edge fingers are not placed at the bottom portion but on the inner (1mm from top layer) and a 0.6mm deep slot is created from the bottom layer to access the edge fingers (total thickness is 1.6 mm).
I already created the Gerber of this PCB (3,4,5) but said edge is on the bottom.. I also attached the 3d in the PDF file
Any feedback will be highly appreciated...

You'll need to talk to the PCB factory. This is a really unusual configuration with the milled slots on only some layers. Off the top of my head I can't even work out what layer stack up would work for this.

Thanks for the reply janekm. I presume this is specially manufactured PCB. Maybe after the 1mm thick PCB is fabricated (complete with trace), then some sort of FR4 and prepeg with 0.6mm thicknes is added on the finished PCB at the bottom. Don't know..maybe..

Does it look fully laminated from the edge? It look like the easiest way is to make base PCB and the top one separately and then just glue them using conventional glues (not a full PCB process).

Gotta be very expensive and labor intensive.

What it this from?

That's kind of what it looks like to me too, because I imagine trying to mill just one prepreg & FR4 sheet together would be messy.

For prototyping I would make the two parts separately, as regular 2-layer PCBs, with alignment holes for some dowel pins and glue it with regular adhesive as you suggested :)

Which a PCB factory should be able to do for you too... the challenge is just documenting exactly what you want done. In terms of file exchange, you would typically put that information on a documentation layer (but also point it out in email during the RFQ process so it's not overlooked).
