The drive to reduced size and increased functionality is a constant in the world of electronic devices. In order to achieve these goals, the industry has responded with ever-smaller devices and the equipment capable of handling these devices. The evolution of BGA packages and leadless devices is pushing existing technologies to the limit of current assembly techniques and materials.As smaller components make their way into the mainstream PCB assembly market, PCB assemblers are reaching the limits of Type 3 solder paste, which is currently in use by most manufacturers.The goal of this study is to determine the impact on solder volume deposition between Type 3, Type 4 and Type 5 SAC305 alloy powder in combination with stainless steel laser cut, electroformed and the emerging laser cut nano-coated stencils. Leadless QFN and μBGA components will be the focus of the test utilizing optimized aperture designs.

. The maximum opening length of the stencil of Full-auto SMT Stencil Printer is 30~50mm on each side. In order to reduce the amount of solder paste added and the contact area between the solder paste and air, the length of the squeegee is smaller

. Cross-sectional analysis was conducted on the U1 BGA56 component based on the analysis illustrated in Figure 16. The cross-sectional analysis revealed that insufficient solder paste transfer occurred at the U1 component location. The lack of solder paste
