LTHJ-SUPER-A1 Gantry welding automatic recovery machine This system is set for one body super new portal welder, special cylindrical welding tools or difficult welding. It adds super negative pressure wind pump on inner side of flux cylinder, so that in the welding process it can absorb unlyzed flux directly into cylinder and place into a small hopper. Open the valve of small hopper and put flux onto work piece, then you can put it into repeated usage.

LTHJ-SUPER-A1型龙门焊自动回收系统本系统是一体超强新型的门式焊机或外圆焊接特制工具、高难度的焊接而设置的，它就是一个焊剂筒内加上超强负压风泵，使在焊接过程中尚未溶化的焊剂直接吸收到筒内，放置到小料斗中，打开小料斗阀门把焊剂放到工件上，进行往复使用。

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。
