A method for the fine-pitch stencil mask design for stencil printing bumping technology for eutectic Sn/Pb and lead-free solder material is described. In the method, a reflowing enhancement layer is introduced to improve the solder quality and reduce the pitch of solder bumps. The method of forming .....

At present, graphite is a commonly used negative electrode material in the commercial graphite based second lithium ion batteries. The theoretical graphite carbon can have a specific capacity of 372 mAh/g, corresponding to an intercalation ratio of lithium to carbon 1:6 (LiC6.). However, such capaci.....
