ABSTRACT:
A washing arrangement for and method of removing burrs of moldable substances from upper and lower major surfaces of lead frames on portions of which the burrs were undesirably applied during molding comprises a transfer assembly which is located outside a washing chamber of the arrangement. The transfer assembly is not subject to the hot and humid environment existing within the washing chamber, thereby preventing corrosion, and facilitating ready inspection and maintenance of the arrangement.
