Abstract: A method for milling flex foil includes providing a web of flex foil including a substrate; a first conductive layer arranged on one surface of the substrate; a second conductive layer arranged on an opposite surface of the substrate; a first insulating layer arranged adjacent to the first conductive layer; and a second insulating layer arranged adjacent to the second conductive layer. The method includes dry milling one side of the web using a first cliché pattern including raised portions and non-raised portions to selectively remove at least one of the first conductive layer and the first insulating layer. The method includes dry milling an opposite side of the web using a second cliché pattern including upper raised portions, lower raised portions and non-raised portions to selectively remove the second insulating layer.

Abstract: A method for operating cyclic process-based systems, with a hot-side reservoir (1) and a cold-side reservoir (2) for a fluid (3), and at least one heat exchanger unit (4) with mechanocaloric material, wherein the mechanocaloric material of the heat exchanger unit (4) is actively connected to the fluid (3) such that heat is transferred between the mechanocaloric material and the fluid (3). It is essential that the transfer of heat between the mechanocaloric material and the fluid (3) takes place essentially by latent heat transfer. A corresponding heat-transfer unit (4) and a corresponding apparatus are also provided.

Abstract: A method for milling flex foil includes providing a web (14) of flex foil including a substrate; a first conductive layer arranged on one surface of the substrate; a second conductive layer arranged on an opposite surface of the substrate; a first insulating layer arranged adjacent to the first conductive layer; and a second insulating layer arranged adjacent to the second conductive layer. The method includes dry milling one side of the web using a milling wheel (20-1) and a first cliche pattern (25-1) (including a rotating drum (24-1) and a flexible substrate (26-1)) including raised portions and non-raised portions to selectively remove at least one of the first conductive layer and the first insulating layer. The method includes dry milling an opposite side of the web using a milling wheel (20-2) and a second cliche pattern (25-2) including upper raised portions, lower raised portions and non-raised portions to selectively remove the second insulating layer.

Abstract: A battery connection assembly includes a frame including a plurality of posts that are spaced by a first distance. A flex foil includes a conductive layer and first and second insulating layers arranged adjacent to the conductive layer. A first plurality of traces is defined in the conductive layer. A plurality of fingers is defined in the conductive layer and partially released from the flex foil, wherein the first insulating layer is removed from the plurality of fingers to expose the conductive layer. A plurality of busbars is connected to the frame and including a first surface, a second surface and a hole from the first surface to the second surface. The plurality of fingers is attached to the first surfaces of the busbar at an attachment location and wherein adhesive in the hole attaches the flex foil to the busbar adjacent to the attachment location.
