How long it takes to design a Baseboard for Computer on Module

        I was very happy to write a post for Altium.

    <div class="blog-content">
        <h2 class="blog-content-heading">Do you plan ahead when working on CPU DDR3 fanout?</h2>
        Choosing the correct VIA for a particular memory group and deciding on how PCB layers will be used can make DDR3 layout a lot easier. Assigning different colors to each memory group help visualize the interface.
    </div>
    <div class="blog-content-img-wrapper">

    <div class="blog-content">
        <h2 class="blog-content-heading">Why to use uVIAs instead of through hole VIAs for Address, Command and Control signals?</h2>
        The Address, Command and Control group has the <b>highest number of signals</b> from the memory groups. If we chose through hole VIAs, we would use a lot of space on all the layers. By choosing uVIAs, we only need the space on the Layer 3 and because uVIA is smaller in diameter, we also have more space to fanout the signals on Layer 3.

        This morning I read “<a href="http://blog.live.altium.com/#Blogs/octopart-extension-release">Altium Designer Extension from Octopart</a>” announcement at the Altium blog. So I decided to test it and it is quite good. <br><br>   

        Simply just press right click in Altium and you can find all the information about the selected component: suppliers, price, stock and download datasheet. Very useful.
