    Blind Via and Via-In-Pad fabrication steps

    I am looking at the fabrication artwork for a reference design. It is a four layer, 1mm thick PCB with 0.4mm pitch BGAs. They use blind vias and VIP for connections from Layer 1 to Layer 2, with 0.1mm silver filled holes. But the stackup calls for core and foil construction, with an FR4 core...

    Laptop for Altium Designer

    I will soon need to use Altium Designer while traveling. Any suggestions for a laptop suitable for a good Altium 'experience'? I'd be interested in hearing about specific models, or short of that, recommendations for processors, memory and graphics engines to look for. Thanks, Randy

    OK to tent unused BGA pads?

    I am trying to avoid using trace/gap sizes below 4 mils. However, I cannot route traces from the inner rings of my BGA between pads without doing so. One option for me is to route the necessary inner ring signals right through some outer ring pads that are not used in my design. But I don't want...

    Altium Copper Pour Algorithm Oddities

    I am working on a PCB design in Altium Designer S09 where I have some rather small geometries. I am experiencing some behavior which I think is strange. My experience with P-CAD is that the copper pour algorithms handled this in a way I like better. Is there some setting I might be able to...

    Altium: Viewing multi-layer pads in current layer color

    Hi, Short version: Is there a way to view multilayer through hole pads in the color of the currently selected copper layer, rather than in the 'Multilayer' color in Altium's Layer Select options window? Longer Version: I have been trying to figure out, without success, a way to view multilayer...

    Altium keep out strategies for components (but not traces)

    I was wondering how others handle the concept of a keep out for components, but allowing traces. For instance, if some mechanical part of the housing comes down and touches (or nearly touches the PCB), I want to be able to route traces there but not place components. If I put some object (Arc...

    Altium Designer library strategies

    Hi, After years using P-CAD, I'm making the switch to AD (S09). After a couple of weeks of struggling (due to all of P-CAD techniques, terminology, etc. that are ingrained in my brain now), I'm starting to get the hang of things with AD. I would like to start my own integrated libraries for...
