Abstract: A method for controlling the beta-tin crystal orientation in solder joints is provided. The method is suitable for joining metallization pads using a solder containing tin and silver. By adjusting the silver content in the solder within a specific range of equal to or more than 2.5 wt. % and less than 3.2 wt. %, the [001] axes of beta-tin crystals in the solder is aligned to be in the direction parallel with a solder/metallization pad interface substantially. Electromigration-induced solder deformations and metallization pad consumption can be significantly reduced when solder joints have such a microstructure. Additionally, the undesired Ag3Sn plates in the solder matrix can be avoided accordingly.

Abstract: A coin-dispensing apparatus includes a coin-dispensing unit having a housing, a drive module, a rotary plate, a coin holder, and a coin-ejecting unit. The housing has coin stops and a coin exit slot. The drive module has a drive shaft that is formed with first meshing elements. The rotary plate is formed with coin holes, ribs, and a shaft hole having second meshing elements meshing with the first meshing elements. The coin holder surrounds the rotary plate and is formed with a gap When the rotary plate is rotated, one of the coin holes is aligned with the coin exit slot, and the ribs cooperate with the coin stops to stop a coin in the coin hole and move the coin out of the same and through the gap. The coin-ejecting unit then ejects the coin through the coin exit slot.

Abstract: An improved apparatus for sorting, counting and dispensing tokens such as coins used in games in which its driven member is composed of a driving block and a turntable set on a spindle of an electric motor so that a simple assembly can be achieved. The turntable is operated within the limitation of a ledge of a hopper so that threading connections can be omitted and the turntable will not separate from the hopper during operation. Furthermore, the improved apparatus has a stop lever mounted on the holder for preventing the tokens from falling from the delivery passages back to the turntable. The turntable is designed with a plurality of flanges extending integrally and upwardly from the surface thereof. The flanges are spaced and arranged to form a plurality of channels therebetween so that fingers of a block of the holder can extend into the channels to smoothly deliver the tokens.
