A method for entity risk management and for accumulating assets for a secure retirement is provided in which a non-MEC life insurance policy that is not considered a single premium insurance policy is purchased and funded over time by an owner of a business through proceeds from a loan made to the business in which the loan is secured by business assets that are then made subject to a UCC financing statement, thereby placing them beyond the reach of general creditors. Part of the loan may be immediately converted to certificates of deposit or other cash-equivalent assets and will be redeemed from time to time and distributed to the owner to pay the premiums on the non-MEC policy. Alternatively, the loan may be drawn against over time, and the draws will be distributed to the owner to pay the premiums. At retirement, the owner will receive some tax-free distributions from the non-MEC policy, as provided by the tax code then in effect, and distributions from the policy combined with other retirement income will provide secure income through the owner's retirement.

A semiconductor device without cantilevered leads uses conductive wires (120) to connect the chip terminals to the leads (110), and a package compound (140) to encapsulate the chip surface (101a) with the terminals, the wires, and the lead surfaces with the attached wires. The chip surface (101b) opposite the terminals together with portions (103) of the chip sidewalls protrude from the package, allowing an unimpeded thermal contact of the protruding chip surface to a substrate (201) to optimize the thermal flux from the chip to the substrate. Solder bodies (250) attached to the compound-free lead surfaces (113b) can be connected to the substrate so that the solder bodies are as elongated as the protruding chip height, facilitating the void-free distribution of an underfill compound into the space between chip and substrate, and improving the absorption of thermomechanical stresses during device operation.

This invention discloses a measurement method of the neutral earth-free distribution network towards the direct earth capacitance. It has such steps as injecting stable current signal from the open-delta of bus-bar potential transformer of the substation, measuring the open-delta voltage and the second star side-voltage.
