PCB review Tuesday technical difficulties

Posted on Tuesday, May 8th, 2012 in PCB Review by Ian

Due to a problem encoding the screen capture the debut of PCB review Tuesday will have to wait. Thanks to everyone who submitted a PCB for comments, we’ll get them up ASAP.

If you’d like someone to give your PCB a second look before you send it to the fab, or just want advise on placement on a new PCB, please post the Cadsoft Eagle files in the forum. We’ll choose a few boards every week and talk about them in a five minute video.

PCB routing is an art. There’s lots of styles, and ours isn’t the right one or the best. Our goal is to start a dialog that helps everyone, including us, make better PCBs.

    What stands for me on the displayed board is the confusion about pin number 1 on the connectors.
    AFAIK a square pad indicates pin number 1. The ICSP connector however has two square pads. Luckily there is also a triangle on the silkscreen to indicate the right pad as pin number 1 i.e. the left one of the two. Furthermore, the silkscreen of the 10pin DIL connector does not match the position of its square pad. Either rotate the silk screen 180 degrees (which means the gap for the plug in the box connector will be on the right side) or swap the positions of the round GND pad and square MISO pad.

    Either way I suggest to:
    1. make sure connectors have only one square pad;
    2. make sure a square pad lines up with its silkscreen.

    I was really looking forward to this today, I hope you iron out your glitches :)

    I think this is an excellent idea for a weekly topic. I’ve designed a few boards, though only etched one of them… And I labeled wrong and let the smoke out of the chip. It was am extremely simple charge pump, but a lesson was learned.

    I have a project that I would like to give as gifts for Christmas… I better start working on it now
