    摘要: A testing scheme for ball-grid array devices of different sizes where the same ball-grid pattern may be tested using the same set of test adapters. A testing scheme includes providing a plurality of devices having a predetermined pattern of solder balls attached, providing a plurality of adapters secured to a test board, each of the adapters including a plurality of test contacts arranged in a pattern corresponding to the predetermined pattern of solder balls, removably attaching the plurality of devices to a device holding apparatus such that the predetermined pattern of solder balls on the devices corresponds to the predetermined pattern of test contacts on the plurality of adapters, then positioning the device holding apparatus to bring the plurality of solder balls in contact with the plurality of test contacts.

    摘要: A leadless image sensor package and methods for its assembly. In a first embodiment, an image sensor chip is mounted within a bottom-side cavity of a package shell in a flip-chip manner such that sensing circuitry on the image sensor chip is exposed through an aperture in the top side of the package shell. A transparent encapsulant material is deposited within the aperture to encase interconnect bonds between the package shell and the image sensor chip. A transparent lid is held in place over the aperture by the encapsulant material. The back surface of the image sensor chip is left exposed. In a second embodiment particularly suitable for high-end image sensors, an encapsulant material is not required. Instead, a backing cap is hermetically sealed to a ledge surface in the package shell to cover the bottom-side cavity. A compression member formed on the backing cap contacts the image sensor chip and maintains interconnect bond integrity.

    摘要: A method for fabricating a chip-scale package includes securing a device substrate that carries at least two adjacent semiconductor devices to a sacrificial substrate. The sacrificial substrate may include conductive elements on a surface thereof, which are located so as to align along a street between each adjacent pair of semiconductor devices on the device substrate. The device substrate is then severed along each street and the newly formed peripheral edge of each semiconductor device coated with dielectric material. If the sacrificial substrate includes conductive elements, they may be exposed between adjacent semiconductor devices and subsequently serve as lower sections of contacts. Peripheral sections of contacts are formed on the peripheral edge. Upper sections of the contacts may also be formed over the active surfaces of the semiconductor devices. Once the contacts are formed, the sacrificial substrate is substantially removed from the back sides of the semiconductor devices.
