Abstract:
A method for arranging print head chips, includes: (a) setting a first fiducial mark and a second fiducial mark on a PCB for determining coordinate positions of a plurality of array units that are arranged on the PCB and calculating a print range of the array units, wherein each array unit has a plurality of spots that are transversely arranged from the first one of the spots to the last one of the spots in sequence; (b) setting a third fiducial mark as a start point for arranging the first spot of a first array unit of the array units on the PCB; and (c) arranging other array units on the PCB in sequence according to the coordinate positions and the start point.
Abstract:
A package structure module with high density electrical connections includes a drive IC structure, an LED array structure, and a plurality of conductive structures. The drive IC structure has a plurality of first open grooves formed on a lateral wall thereof. The LED array structure has a plurality of second open grooves formed on a lateral wall thereof to respectively face the first open grooves. Each conductive structure traverse the corresponding first open groove and the corresponding second open groove in order to electrically connect between the drive IC structure and the LED array structure.
Abstract:
A semiconductor wafer is disclosed that includes a plurality of fields, including a plurality of alignment fields. Each alignment field includes a plurality of intra-field small scribe lane primary mark (SSPM) overlay mark pairs there around. The SSPM mark pairs allow for in-situ, non-passive intra-field alignment correction. In one embodiment, there may be between two and four alignment fields, and between two and four SSPM mark pairs around each alignment field. The SSPM marks of each mark pair may be extra scribe-lane marks.
Abstract:
The light emitting module includes a substrate, a light emitting element and a driving circuit chip. The light emitting element is attached to the substrate and has a plurality of first contacts on a top surface thereof. The driving circuit chip is attached onto the substrate and has a plurality of second contacts in direct connection to the first contacts one on one when being placed above the light emitting element.
Abstract:
A support stand includes a folding board, an upper cover mounted on an upper end of the folding board and having a bottom formed with an insert inserted into the upper end of the folding board, and a lower cover mounted on a lower end of the folding board and having a top formed with an insert inserted into the lower end of the folding board. Thus, the support stand is assembled easily and conveniently, thereby facilitating the user assembling the support stand. In addition, the support stand is mounted on the playing table easily, thereby facilitating the user mounting the support stand on the playing table.
Abstract:
A hockey playing table includes a main body, a panel mounted on the main body, a magnetic board mounted on the panel, a disk movably mounted on the magnetic board, and a circular magnetic plate mounted on a bottom of the disk and rested on the magnetic board. Thus, the disk is floating on the magnetic board during movement by the repulsive force between the magnetic plate and the magnetic board, so that the disk is moved on the magnetic board easily and conveniently, thereby facilitating the player playing the hockey game.
Abstract:
A method of deodorant for kitchen disposal or toilet pipeline is to prearrange fermentation catalyst at a water inlet with preserved water therein to dissolve a portion of the fermentation catalyst and to flow through a pipeline to the final destination.
Abstract:
A rotating device has a turning wheel, a threaded sleeve, and a nut. The turning wheel has a hub having a center hole, a wheel rim, and a plurality of spokes connected to the hub and the wheel rim. The threaded sleeve has a flange and an outer thread. The threaded sleeve is inserted through the center hole of the hub and a through hole of a table plate. The nut engages with the outer thread of the threaded sleeve. An umbrella has a center post inserted through the threaded sleeve.
Abstract:
A device includes a spacer, which includes a recess extending from a top surface of the spacer into the spacer, and a conductive feature including a first portion and a second portion continuously connected to the first portion. The first portion extends into the recess. The second portion is on the top surface of the spacer. A die is attached to the spacer, and a lower portion of the first die extends into the recess.
Abstract:
A projection apparatus includes an illuminating unit, an imaging unit, a lens unit, and a control unit. The illuminating unit includes a light source, and a light source driving module operable to drive the light source to provide an illumination beam. The imaging unit is operable so as to modulate the illumination beam into an image beam. The lens unit is disposed on an optical path of the image beam for projecting the image beam. The control unit is coupled electrically to the illuminating unit and the imaging unit. The control unit is configured to execute an activating thread for initializing the imaging unit after controlling initial driving of the light source by the light source driving module, and a monitoring thread for monitoring the light source driving module for a success signal that indicates successful provision of the illumination beam by the light source.
