In the light of cost index and pollution degree, the characteristics of kinds of pulp are analyzed in detail, and the GP pulp which is low cost, high-yield, no-pollution is chosen as the material of tableware. Based on material element analyzed, shaping technology is designed, the to and for single plane shaping equipment which is high shaping quality, high production efficiency and is easy to automatize is chosen. All kinds of measure are taken to solve the problems which are inequality in the shaping process of GP pulp, and dosage which matches with GP pulp is chosen. Some ways of fixing shape and heat up are analyzed, the technology of saving energy of heat pressing to fix shape being composed of oil heat and only one fixed shape in the mold is applied, with which it is high production efficiency, low cost to fix shape effectively, which saves energy 30 percent. In order to make the production line meet with material of GP pulp, measure are taken to solve the problem of pulp adhered to netlike molding which can lead to carry material difficult, the structure of fully automatic equipment is renovated, the loaded beam is optimizationally designed to make equipment structure compactand improve location precision and products quality. According to technologic flow and actual characteristic, Omron PLC is chosen as the core of the control system, proximity switch as detect unit take the place of touch switch, software is designed reasonably according to time order figure, hardware is simplified, the reliability of system is advanced, the stability of system is assured to make production order. Intelligence neuron PID system is studied theoretically which is made up of both neuron with self-organizing and self-learning function and ordinary PID with the characteristic of the simple structure and high stability, which can automatically tune the parameter with the change of system parameter, remain perfect performance.

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。

In the paper, the vacuum infusion molding process based on grooves was investigated by experiments, and the parameters of width, d e pth and spacing for flow grooves and spacing for supply grooves were optimized a ccording on the molding experiments and various factors that had influence on th e mold filling process were discussed.
