The height of central part of the round cambered surface is equal or higher than the one of ring- shaped bulge. When the horizontal top side of internal cavity of encapsulation mold is pressed down to the heat sink so as to produce a deformation, the cambered surface can not be pressed to oppress the subjacent metal line, and the ring-shaped bulge can also prevent mold-overflow.

该散热片，适用于封装制程，具有一圆形弧面板部，并且其圆形弧面板部的中央是高于或等于环状凸起的高度；如此一来，当封胶模具内模穴的水平顶面下压至散热片上而使其产生变形时，圆形弧面板部就不会压迫到下方的金属线，而环状凸起同样也可发挥防止溢胶的功能。
