The bars are selectively processed and removed to separate them into pellets, and then pellets 1
In order to separate and rearrange the semiconductor pellets one by one, the wax was melted on a dove plate at a temperature of 100 to 200"0, and the pellets were separated from the quartz plate using a pellet adsorption jig, and then attached to the semiconductor pellets. The wax was removed by spraying an organic solvent for 6 to 8 seconds with a spray gun, and then arranged on another array plate.

喪。When handling pellets, the pellets and quartz plate are pasted together with wax, and the wax is heated on a houdo plate at a temperature of 100 to 200"0 to melt the wax, and the wax is placed on a pellet adsorption jig. After separating the pellet from the quartz plate, remove the wax adhering to the wiring surface and back surface of the semiconductor pellet by spraying an organic solvent at room temperature of 15 to 9 degrees Celsius for 6 to 8 seconds with a spray gun. Although it is lined up on the array board, it takes a long time to wash the wax, and sometimes the wax cannot be completely removed.
