A system and method of planarizing a layer are disclosed. Topography of the layer is measured to produce a topographic map, which is then digitized into blocks of that indicate different thickness variation. Laser conditions are assigned for each block, a laser steered to planarization blocks where material is to be removed, and the material ablated at each planarization block. In-situ monitoring of the surface profile provides feedback to adjust the laser conditions during planarization. When depth control is used, the laser is focused at a focal plane and has a focal depth beyond which no material is ablated and the laser is steered across the entire layer. A thin metal layer of higher ablation threshold than the dielectric layer formed over the layer provides added selectivity, with the laser conditions changed after ablation of the metal layer. Otherwise, planarization is limited to the planarization blocks.

A camera module, a molded circuit board assembly, a molded photosensitive assembly and manufacturing method thereof are disclosed. The camera module includes a molded base which is integrally formed with a circuit board through a molding process, wherein a photosensitive element may be electrically connected on the circuit board and at least a portion of a non-photosensitive area portion of the photosensitive element is also connected by the molded base through the molding process. A light window is formed in a central portion of the molded base to provide a light path for the photosensitive element, wherein a cross section of the light window is configured to have a trapezoidal or multi-step trapezoidal shape which has a size increasing from bottom to top to facilitate demoulding and avoiding stray lights.

An apparatus, system, and method for automatically dispensing and embedding components into three-dimensional parts. In an example embodiment, a direct wire embedding head can be fixed on an automation motion system. The direct wire embedding head begins and terminates an embedded wire pattern on a layer or on a surface of a three-dimensional part in order to automatically create the embedded wire pattern. A sensor is located on an embedding surface wherein the embedded wire pattern is embedded. The sensor can measure the distance between the direct wire embedding head and the embedding surface. A predefined distance can be maintained to ensure successful embedding results for the embedded wire pattern by automatically adjusting a position of the direct wire embedding head in response to feedback from the sensor.

A process includes utilizing a pin array that includes multiple segmented pins for forming selectively plated through holes. The process includes forming a PCB laminate structure that includes multiple spinel-doped core layers and multiple through holes. Each spinel-doped core layer includes a heat-activated spinel material incorporated into a dielectric material. The process includes aligning individual segmented pins of a pin array with corresponding through holes of the PCB laminate structure, where each segmented pin includes heated segment(s) and insulating segment(s). The process includes inserting the segmented pins of the pin array into the corresponding through holes and generating heat within each heated pin segment that is sufficient to form metal nuclei sites in selected regions of the spinel-doped core layers adjacent to portions of the through holes that contain the heated pin segments. The metal nuclei sites function as seed layers to enable formation of selectively plated through holes.

Embodiments relate to an apparatus for rework of a BGA package. Memory shape material is placed adjacent to a plurality of solder joints of the package. Stimulation is applied to the material, with the stimulation causing the material to change from a non-stimulated shape to a stimulated shape. This stimulation causes an expansion of the material. As the material expands, it exerts a tensile force on the BGA package and an adjacently positioned carrier, causing a separation of the two components, while mitigating collateral heat of adjacently positioned components.
