As the brittleness of low-k material,the traditional wire bonding parameter often lead to die pad crack or Au-AL matter bad;after used low-k material,die size,die pad opening and die pad pitch change to more little,wire change to lengther and density change to more higher,it\' s new challenge for molding and wire bonding;at the same time, low-k material also require to control the thermal stress in package.

由于低介电常数材料的脆性，传统的引线压焊参数设置将会导致焊盘碎裂以及金铝化合物不良；由于使用低介电常数材料后，芯片尺寸、压焊区域和压焊间距进一步减小，金线压焊长度和密度大大增加，这就为压焊和模塑提出了新的要求；同样由于低介电常数材料的应用，对封装体内部的热应力的控制也提出了更高的要求。
