In one example, a system comprises a laser assisted bonding (LAB) tool. The LAB tool comprises a stage block and a first lateral laser source facing the stage block from a lateral side of the stage block. The stage block is configured to support a substrate and a first electronic component coupled with the substrate, and the first electronic component comprises a first interconnect. The first lateral laser source is configured to emit a first lateral laser beam laterally toward the stage block to induce a first heat on the first interconnect to bond the first interconnect with the substrate. Other examples and related methods are also disclosed herein.

The present invention relates to a cassette module for controlling fluid flows, in particular for use in blood treatment systems or in infusion systems, wherein the cassette module comprises at least one base body having means for the flow guidance of at least one fluid flow and at least two membranes which are at least sectionally directly or indirectly in contact with the base body, wherein at least one actuation element is arranged between the membranes by means of which the means for the flow guidance can be acted on.

The application discloses a display screen. The display screen includes a screen body including a cover glass and a substrate glass. The cover glass and the substrate glass each has a bonding surface and an outer surface opposite to the bonding surface. The outer surfaces of the cover glass and the substrate glass are provided with a cracking prevention layer at least in a peripheral region of a predetermined slotted region of the screen body. In a screen body cutting method disclosed in the application, cracking prevention layers are formed on the outer surfaces of both the cover glass and the substrate glass, so as to reduce the edge cracking or breaking of the screen body during the slotting and to reduce crack generated in the cover glass and the substrate glass, thereby improving overall strength of the screen body and increasing the yield of the product.

A negative electrode for an electrochemical cell of a lithium metal battery may be manufactured by joining together a metallic current collector piece and a lithium metal piece. The metallic current collector piece may be positioned adjacent the lithium metal piece in an at least partially lapped configuration at a weld site. A laser beam may be directed at an upper surface of the metallic current collector piece at the weld site to melt a portion of the lithium metal piece adjacent the metallic current collector piece and produce a lithium metal molten weld pool. The second laser beam may be terminated to solidify the lithium metal molten weld pool into a solid weld joint that physically bonds the lithium metal piece and the metallic current collector piece together at the weld site.
