Method and system for removing resin bleed from electronic components

摘要

Disclosed is an in-line electrolytic deflash system and method for removing resin bleed and other materials from the leads of an encapsulated electronic component. An encapsulated electronic component is carried on a continuous belt through the system. The component first passes through an electrolytic deflash station which includes tanks filled with a deflash solution for loosening the resin bleed. The component is then rinsed in a low pressure rinse station, and then carried through a high pressure rinse station where the loosened resin bleed is removed from the component. The component is then further rinsed with both tap water and a deionized water. Once the component has been sufficiently rinsed any remaining moisture is blown off the part in an air knife station and the component is then passed through a dryer which completely removes any moisture remaining on the component.
