Abstract:
The invention relates to a method for producing a substrate arrangement (10, 10") for connecting to an electronic component (30), comprising the steps of: providing a substrate (11) that has a first side (12) and a second side (13), applying a contacting material layer (15) to the first side (12) of said substrate (11), and applying a pre-fixation agent (18) to at least some sections of a side (16) of the contacting material layer (15) that faces away from said substrate (11). The invention also relates to a corresponding substrate arrangement (10, 10") and to a corresponding method for connecting at least one electronic component (30) to the substrate arrangement (10, 10"). The claimed measures provide for sufficient handling strength during transportation from the place of assembly to the place of connection. The contacting material layer (15) should preferably be applied across the whole surface, or close to the whole surface, on the first side (12) of the substrate (11). The substrate (11), with the applied contacting material layer (15) and the applied pre-fixation agent (18), can be positioned detachably on a carrier (20). When connecting to the electronic component (30, 30'), the substrate arrangement (10, 10") is sintered, crimped, soldered and/or bonded thereto. The substrate (11) can be a metal sheet or a metal strip section, particularly a copper sheet or a copper strip section, a lead frame, a DCB substrate or a PCB substrate. The electronic component (30) can be a semiconductor, a DCB substrate or a PCB substrate.

Abstract:
The invention relates to a method for separating surface-mountable semiconductor components (1) and for fitting external contact surfaces to said components. According to the invention, semiconductor components are applied to a metal support (4) in rows (5) and columns (6) in corresponding semiconductor component positions (7) of said support (4). A plurality of semiconductor component positions (7) with their respective components are then potted in a plastic housing mass (8), thus producing a composite board (3), which is then separated into individual semiconductor components (1) by laser ablation, said components receiving a laser inscription on their upper faces (13). Said upper faces (13) can then be stuck to an adhesive film, so that it is possible to expose the undersides whilst maintaining the semiconductor component positions (7).

Abstract:
A pressure-sensitive adhesive sheet exfoliative with heat having, on at least one side of a substrate, a thermally expandable layer containing thermally expandable microspheres and an adhesive layer containing an adhesive material, wherein the substrate has good thermal resistance and elasticity. The inventive adhesive sheet is advantageous in that, when a body having a sheet adhered thereon is cut, the use of the inventive sheet results in a high operability and workability in an exfoliation and recovery step, since pieces formed by cutting can hold a satisfactory distance from one another and are resistant to a heat treatment applied for expanding the thermally expandable layer.
