A leadframe having a die thereon connects a high current conductive area on the die to a leadframe contact using copper clip that include a structure portion that is received with a recess-like "tub" that is formed in the leadframe contact which tub is shaped to conform to the geometric shape of the clip. In the preferred embodiment, a leadframe structure fabricated by etching includes at least one contact that is a half-etch recess or "tub" that receives one end of the clip structure and is retained in the tub by an adhesive. The end of the clip that is received in the tub is held in place during subsequent handling until the clip and leadframe undergo solder reflow to effect an electrical connection sufficient to handle the current load and a also effect a reliable mechanical connection.
