    Sven,
    Get a chip for SMD mounting and lay it at the place it on the board. You know that the first pin is always the top left. If the first pin of IC match marked with a white dot on the board first pin it means that you have no problem. If there is a discrepancy and white point is on the other side of the IC it means that there is a problem. Then the only solution is to solder IC lying on his back to have matching pins. There is another solution - order a new PCB but this time with proper placement of ICs.
    I looked boards of ivkonic and I can say that he has turned layers of the PCB. Green layer, shown as C2, really should be a layer C1 /standing on top of the board and/ vice versa C1 blue layer should be a layer C2 /standing bottom the board/.

      IVCONIC what do you say about the mirror image of your PCB?

      • He says that, I suppose.

        It only happens to those who undertake.

          These boards are correct,but the file that is shared here is obviously wrong

                    Yes layers are reversed on those pcbs.
                    How that happened?
                    It should be taken care which layer goes where in process of exporting to gerber format.
                    Whatever the layer is used as top or bottom in Sprint Layout; later it can be exported to gerber also as mirrored.
                    Mistake is mine, because i used green layer as top and blue layer as bottom and haven't pointed that earlier!
                    I thought it was obvious, looking on the marks at integral circuits...
                    People from Elcrow are accepting only gerber format, so it was completely irrelevant how i will arrange them in Sprint Layout.
                    Because later in process of exporting to gerber; layers are easily mirrored if needed.
                    Yet... i did draw the pcb, i made mistake because i haven't pointed out on that...
                    What to do with those pcbs?
                    IC chips can be soldered flipped backward so as transistors. Other components even more easier.
                    Those pcbs are still usable.

                      will there be a correct files or to offer motherboards sales

                        Actually those are correct too.
                        If you print "films" directly from Sprint Layout; just do mirror both layers (in printing dialogue).
                        If you export them to gerber, you can export them mirrored... or export them as they are and later just rename gerbers.

                            • Well, since my PCB's are wrong. Looking at them......it would be too much of a pain in the butt to build and bend IC legs, transistors etc. backwards.
                              I can see myself getting confused and getting some parts mixed up, taking up too much time to try and complete.........
                              So I either spend more money on new PCB's using correct files , quit throw the electronic parts in a box or sll em and go buy a Golden Mask to go with my search coil.
                              Think I spent $250+ for 10 PCB's and all the electronic components to build 10 units. So if anyone wants the parts For $150 plus shipping, I will throw in the PCB's.

                              • it is better to make this board if correct
