Disclosed herein are unitary printed circuit boards (PCBs) and methods of using them for testing an integrated circuit (IC). In some embodiments, a unitary PCB comprises a main board portion and a flexible PCB portion, which are configured to be detached from each other at a separation location on the unitary PCB. The main board portion comprises a plurality of pads, and the flexible PCB portion comprises a plurality of through-holes, where a layout of the through-holes corresponds to a layout of the plurality of pads. In some embodiments, a method of testing an IC of a device comprises separating the unitary PBC into a main board portion and a flexible PCB portion, attaching the IC to the main board portion, soldering the main board portion to a platform PCB of the device, and attaching the flexible PCB portion to the main board portion.

An approach to provide an electronic assembly process that includes receiving at least one electronic assembly after a solder reflow process using a Sn-containing solder and a water-soluble flux. The approach includes baking the at least one electronic assembly in an oxygen containing environment and, then cleaning the at least one electronic assembly in an aqueous cleaning process.

The present application provides a reflow oven (100) and a gas recovery method. The reflow oven (100) comprises a reflow oven hearth (101), a separator (105), the separator inlet (110) being connected to the gas outlet (102) of the reflow oven hearth (101) so that the gases in the reflow oven hearth (101) can flow into the separator (105), a zeolite box (107), the zeolite box inlet (112) being connected to the separator outlet (111), and the zeolite box outlet (113) being connected to the gas inlet (103) of the reflow oven hearth (101) so that the gases flowing through the separator (105) can enter the zeolite box (107) and the gases flowing through the zeolite box (107) can flow out of the zeolite box outlet (113), a sensor (106), which is provided in the gas passage between said zeolite box outlet (113) and the gas inlet (103) of the reflow oven hearth (101). The reflow oven (100) in the present application enables the gases flowing through the separator (105) to enter the zeolite box (107). After most of the flux is removed from the gases in the separator (105), the flux is further removed in the zeolite box (107). In addition, polygonal zeolites have certain volumes and are supported in the zeolite box (107) to form clearances, and thus almost no resistance is brought about to the flow of the gases in the zeolite box (107).

An LED tube lamp comprises a glass lamp tube having a main body, two end caps coupled to a respective end of the tube, an LED light strip adhered to inner circumferential surface of the tube by first adhesive, a plurality of LED light sources mounted on a mounting region, a power supply module having a circuit board and a plurality of electronic components mounted on the circuit board, a diffusion layer covering on outer surface or inner surface of the tube, and a protective layer being disposed on surface of the strip and having a plurality of first openings for disposing the plurality of LED light sources. The strip comprises the mounting region and connecting region at an end of the strip. The circuit board is substantially parallel with axial direction of the tube, electrically connects to the connecting region, and stacks with a portion of the connecting region.

A ceramic circuit substrate having high bonding performance and excellent thermal cycling resistance properties, wherein a ceramic substrate and a copper plate are bonded by a braze material containing Ag and Cu, at least one active metal component selected from Ti and Zr, and at least one element selected from among In, Zn, Cd, and Sn, wherein a braze material layer, after bonding, has a continuity ratio of 80% or higher and a Vickers hardness of 60 to 85 Hv.

A device configured for a laser treatment, including a support and objects, each attached to the support via a region absorbing for the laser, the support comprising a system for optically guiding (42, 44, 50, 52) the laser towards at least a plurality of said absorbing regions.

According to the present invention, there is provided a copper/ceramic bonded body including: a copper member made of copper or a copper alloy; and a ceramic member made of silicon-containing ceramics, the copper member and the ceramic member being bonded to each other, in which a maximum indentation hardness in a region is set to be in a range of 70 mgf/μm.sup.2 or more and 150 mgf/μm.sup.2 or less, the region being from 10 μm to 50 μm with reference to a bonded interface between the copper member and the ceramic member toward the copper member side.

Systems and methods for printing a printed circuit board (PCB) from substrate to full integration utilize a laser-assisted deposition (LAD) system to print a flowable material on top of a substrate by laser jetting to create a PCB structure to be used as an electronic device. One such system for PCB printing includes a jet printing unit, an imaging unit, curing units, and a drilling unit to print metals and other materials (e.g., epoxies, solder masks, etc.) directly on a PCB substrate such as a glass-reinforced epoxy laminate material (e.g., FR4). The jet printing unit can also be used for sintering and/or ablating materials. Printed materials are cured by heat or by infrared (IR) or ultraviolet (UV) radiation. PCBs produced according to the present systems and methods may be single-sided or double-sided.

There is provided a method which includes placing a component on a substrate and extending an alignment member through an opening in the substrate. Once the alignment member is extended through the opening, the component is moved to abut against the alignment member to align the component relative to the substrate. After the component is aligned relative to the substrate, the component is secured to the substrate and the alignment member is retracted through the opening.
