Claim 17:
18. A packaged semiconductor device, comprising:
a package substrate having a die side surface and an opposing board side surface;
leads in the package substrate spaced from one another;
cavities extending into the leads from the die side surface of the leads in the package substrate, the cavities having sides and a bottom surface of the lead material;
a semiconductor die flip chip mounted to the die side surface of the package substrate, the semiconductor die comprising post connects extending from bond pads on a device side of the semiconductor die, the post connects on the bond pads at a proximal end and extending to a distal end spaced from the bond pads, the post connects bonded to the leads on the package substrate by solder joints formed in the cavities, wherein the solder joints have a thickness, and the cavities have a depth greater than the thickness.
