Abstract
PURPOSE: To remove easily a thin flash, which is generated at a resin seal time, by jetted flow of liquid or air.
CONSTITUTION: Water is jetted from a nozzle to blow off the thin flash between a resin seal body and a lead. By this method, washing of organic materials becomes needless after processing because dirt is not sticked. Water can be used repeatedly by filtering, and the device can be prevented from being injured. When organic chemicals such as alcohol are used in stead of water, the drying process is shorted, and the drying process becomes needless if the thin flash above can be removed by air.
