A method for encapsulating a device, such as an battery, having two opposite and parallel main faces and a peripheral edge, wherein one main face includes an electrical contact zone, includes the steps of retaining the device within an injection chamber of a mold and injecting encapsulation material into the injection chamber to overmold an encapsulation block on the device. The injection chamber is configured to hold a portion of the device, adjacent its peripheral edge, so as to center the device within the injection chamber. The mold includes centering structures that at least partially cover the electrical contact zone. Opposite positioning studs protrude into the injection chamber and bear on the opposite main faces of the device. The resulting packaged device includes an overmolded encapsulation block enveloping the device except for portions covered by the centering structure.

Method of encapsulating an electrical energy accumulation component

A method for manufacturing semiconductor chips from a semiconductor wafer, including the steps of: fastening, on a first support frame, a second support frame having outer dimensions smaller than the outer dimensions of the first frame and greater than the inner dimensions of the first frame; arranging the wafer on a surface of a film stretched on the second frame; carrying out wafer processing operations by using equipment capable of receiving the first frame; separating the second frame from the first frame and removing the first frame; and carrying out wafer processing operations by using equipment capable of receiving the second frame.

Method for manufacturing semiconductor chips from a semiconductor wafer

A silicon chip surface mounted via balls attached to its front surface, wherein the front and rear surfaces of the chip are covered with a thermosetting epoxy resin having the following characteristics: the resin contains a proportion ranging from 45 to 60% by weight of a load formed of carbon fiber particles with a maximum size of 20 &#x3bc;m and with its largest portion having a diameter ranging between 2 and 8 &#x3bc;m, on the front surface side, the loaded resin covers from 45 to 60% of the ball height, on the rear surface side, the loaded resin has a thickness ranging between 80 and 150 &#x3bc;m.
