bat85 connections

[estregan]

Hi, were now in the process of soldering the components for our megadrum. We used the pcb layout you uploaded. Question is, from the schematic diagram of analog board, all the anode of bat85 are connected to Vcc and cathode is connected to ground BUT on the pcb itself, its reversed i.e. all anode goes to ground while all cathode goes to Vcc.

Are we seeing it correctly or we just inhaled too much solder?

Thanks for noticing the error! On the schematics anodes of D2,D4,D6...D32 are connected to the ground and cathodes of D1,D3,D5...D31 are connected to Vcc and this is correct. On the PCB diodes are incorrectly reversed. I'll update the schematics with the correct placement.

No problem. This means I have to make another analog board right? Also, may I ask how the error came to be when you just need to create the board from the schematics? Is this an error of diptrace? Cause I use diptrace myself and now I'm thinking my pcbs might have errors too even if I just created them from the schematics.

Thanks for the quick reply.

You don't need to make another PCB. Just solder diodes in correctly. Btw, I've already updated PCB design for the analogue board.
The error crept in because when I attached a pattern for this diode I missasigned pins. In essence it doesn't change the PCB, only silk for diodes is incorrect, all the traces are correct.

Good to know then. We'll just make the necessary corrections and update here what happens. Thanks!
