Abstract: The present invention provides a manufacturing method of a semiconductor packaging member, a semiconductor packaging member and a mounting method thereof. The manufacturing method includes the following steps of: pre-molding packaging a lead frame, forming a pre-molding package body both between a lead and a base, and between two adjacent leads in each lead frame unit; forming a groove by thinning an outer lead from a front surface of the outer lead; forming a tin block in the groove; mounting a chip on the base island; plastic-packaging the lead frame which has completed the wire-bonded; forming a semifinished product by forming a tin-plated layer in an exposed region of a back surface of the plastic-packaged lead frame; and forming a single semiconductor packaging member by cutting the semifinished product, the tin block in the semiconductor packaging member is exposed away from the base island.

Abstract: A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.
