| Abstract: |
| To realize high efficiency, low cost batch manufacturing of stainless steel package substrate, the micro stamping process of the stainless steel sheet was studied. Multi-functions of the automatic feeding, positioning, blanking, micro-punching and micro deep drawing was designed into an efficient, complex, high precision package substrate device. To analyze the Influence of molding conditions on the forming quality, the optimal process parameters were determined. At the same time, the shock resistance performance of stainless steel plates was tested. The obtained results show thatusing this the complex integration progressive micro stamping die device can create high quality stainless steel package substrates with a forming efficiency up to 1 120 pieces/h. With overloading of above 47 800 g, package substrates remain surface flat without obvious deformation, which can meet the performance requirements of mechanical property. Using this efficient micro forming technology can solve the size precision of micro components, improve the mechanical properties of micro components,, reduce the production cost, and realize high efficiency, low cost package substrate batch manufacturing. |
