    有幸在7月购得一片Matrox Parhelia PH-A128R的工程样卡 ,这也是偶的第二片出自Matrox的工程样卡,实在很难找~~ 由此可知Matrox对这类卡管理的很严格

    先来看一下主卡正面吧,不同于零售版本,PCB使用的是黄绿色的染料,下层PCB的敷铜能很容易的被识别出来,其次PCB的质地也有所不同,这片工程卡采用了磨砂质感的PCB材料

    从PCB版本号我们能发现,这片采用了称为7082-04 Rev.A的型号,而在正式发售后换而到7082-0401 Rev.A。至少从正反面我可视的布线上我没看出什么明显差别来

    LPF,低通电路,模拟输出质量的灵魂之一,此处为DVI-2的低通滤波电路特写图,位于PCB正面

    采用了高档的绕组贴片电感

    背面,DVI-1的LPF看起来更加养眼,零售版只是用到了图中白色的普通贴片电感

    所有焊点都均匀饱满,甚至空焊位也一样养眼

    这张图是最有说服力的。来证明为什么我称其为ES,工程样卡,核心揭开散热器后,一片空白。。。。Logo都没的打

    M卡做工真是养眼啊~~

    PS:这卡发热也真大,核心和Q3处的PCB都变色了

    Q3那颗IR的7311或者7313在这卡上是出了名热,用久了的卡都会变色,核心那块其实因为样品的关系,估计是最后装的核心,上了很多助焊剂,助焊剂透到背面了,时间长了就把PCB白色的元件型号标识给变色了
