10804667 · 2020-10-13 · ·

A device for automatically mounting a connector-housing with a contact-part attached to an electrical line includes a holder, a movable-gripper, an alignment-station, a camera, and a control-device. The holder fixes the connector-housing. The movable-gripper holds the contact-part and inserts the contact-part into a cavity of the connector-housing. The alignment-station includes an alignment-gripper that holds the contact-part and rotates the contact-part about a rotation-axis parallel to an insertion-direction. The camera determines an actual-rotational-position of the contact-part held by the alignment-gripper in relation to the rotation-axis. The control-device compares the actual-rotational-position with a predetermined-rotational-position based on the characteristics and arrangement of the connector-housing. The control-device further controls the alignment-gripper to perform a corrective rotational movement based on the result of the comparison.

Panel-molded electronic assemblies

A method of encapsulating a panel of electronic components such as power converters reduces wasted printed circuit board area. The panel, which may include a plurality of components, may be cut into one or more individual pieces after encapsulation with the mold forming part of the finished product, e.g. providing heat sink fins or a surface mount solderable surface. Interconnection features provided along boundaries of individual circuits are exposed during the singulation process providing electrical connections to the components without wasting valuable PCB surface area. The molds may include various internal features such as registration features accurately locating the circuit board within the mold cavity, interlocking contours for structural integrity of the singulated module, contours to match component shapes and sizes enhancing heat removal from internal components and reducing the required volume of encapsulant, clearance channels providing safety agency spacing and setbacks for the interconnects. Wide cuts may be made in the molds after encapsulation reducing thermal stresses and reducing the thickness of material to be cut during subsequent singulation. External mold features can include various fin configurations for heat sinks, flat surfaces for surface mounting or soldering, etc. Blank mold panels may be machined to provide some or all of the above features in an on-demand manufacturing system. Connection adapters may be provided to use the modules in vertical or horizontal mounting positions in connector, through-hole, surface-mount solder variations. The interconnects may be plated to provide a connectorized module that may be inserted into a mating connector.

Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause phototransistors or electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler. A set of micro-object may be analyzed. Geometric properties of the set of micro-objects may be identified. The set of micro-objects may be divided into multiple sub-sets of micro-objects based on the one or more geometric properties and one or more control patterns.

Method of Enhancing Fatigue Life of Grid Arrays
20200146157 · 2020-05-07 ·

A method is presented that improves reliability for the mechanical electrical connection formed between a grid array device, such as a pin grid array device (PGA) or a column grid array device (CGA), and a substrate such as a printed circuit board (PCB). Between adjacent PCB pads, the method increases a spacing pattern toward the periphery of the CGA, creating a misalignment between pads and columns. As part of the method, columns align with the pads, resulting in column tilt that increases from the center to the periphery of the CGA. An advantage of the method is that the column tilt reduces the amount of contractions and expansions of columns during thermal cycling, thereby increasing the projected life of CGA. Another advantage of the method is that it reduces shear stress, further increasing the projected life of the CGA.
