The resilient mounting frame has an ejection assembly opposite the hinging of the resilient mounting frame and keyboard component, allowing one-handed release of the tablet PC, and an embedded implant corresponding to and detectable by a configurable circuit board encased in the keyboard component.

A process for fabricating a leadless plastic chip carrier includes laminating a first metal strip to a second metal strip to form a leadframe strip, selectively etching the first metal strip to define at least a row of contact pads, mounting a semiconductor die to either a die attach pad or the second metal strip and wire bonding the semiconductor die to ones of the contact pads, encapsulating a top surface of the leadframe strip in a molding material, removing the second metal strip, thereby exposing the die attach pad and the at least one row of contact pads, and singulating the leadless plastic chip carrier from the leadframe strip.

A method of making a lead frame and a partially patterned lead frame package with near-chip scale packaging lead-count, wherein the method lends itself to better automation of the manufacturing line and improved quality and reliability of the packages produced therefrom. A major portion of the manufacturing process steps is performed with a partially patterned strip of metal formed into a web-like lead frame on one side so that the web-like lead frame is also rigid mechanically and robust thermally to perform without distortion or deformation during the chip-attach and wire bond processes, both at the chip level and the package level. The bottom side of the metal lead frame is patterned to isolate the chip-pad and the wire bond contacts only after the front side, including the chip and wires, is hermetically sealed with an encapsulant. The resultant package being electrically isolated enables strip testing and reliable singulation.

A color coded flexible armored cable includes a tubular sheath formed from a metal strip having a continuous, non-patterned, non-conductive color coating applied to the entirety of an abraded outer surface of the strip. The color coating is of a predetermined precise thickness and includes a polyethylene based wax lubricant in a percent by volume of about 0.45 to 0.55. The strip is formed into helical convolutions having a cross-sectional shape which provides for overlap and interlocking of adjacent convolutions and contact between adjacent convolutions along a helical line such that, upon bending the sheath, the convolutions remain in contact at a trailing edge of one convolution and the inner surface of an adjacent convolution in a way such that the color coating is not scraped off of the outer surface of the sheath. The sheath is preferably formed such that the number of convolutions per unit length of sheath is maximum for sheath flexibility and retention of the coating on the outer surface of the sheath.

This invention pertains to electrochemical cells, typically to air depolarized cells of the button-type. Non-reactive elements of cells of the invention are thinner than corresponding non-reactive elements of prior art cells. Such elements can be made thinner because of improved structures of such elements. The anode can is made from a metal strip structure having a higher steel content. The cathode can preferably has improved stiffness and rigidity while retaining sufficient ductility to tolerate forming the cathode can. By so reducing the thicknesses of non-reactive elements of the cell, and thus the volume occupied by such non-reactive elements, the fraction of the cell devoted to holding electrochemically reactive anode material therein is increased, with corresponding increase in the milliampere hour capacity of the cell.
