AI Technical Summary

Problems solved by technology

Because the extrusion ram must be heated during at least part of the lamination step, the extrusion ram may change shape slightly due to heating, so that the extrusion surfaces will not be perfectly parallel
This causes the lamination pressure to vary at different points of the laminated film, thereby adversely affecting the quality of the laminate

Embodiment Construction

[0013] The extrusion head 1 is arranged in a lamination press, which is not shown in the figure, but is known to experts in the field from DE8518808U1. Extrusion head 1 has upper head 2 and bottom head 3 . The pressing surface 4 of the bottom ram 3 is covered by a plastic layer 5 made of silicone. The bottom ram 3 comprises grooves 6, 6' which divide the pressing surface 4 into separate partial surfaces. As an example, the groove 6 is formed in the bottom indenter 3 before the plastic layer 5 is applied, and the groove 6' is formed in the bottom indenter 3 after the plastic layer 5 is applied. Therefore, the surface of the groove 6 is also covered by plastic, while the surface of the groove 6' is not covered by plastic. Coating can be performed on the upper or lower indenter, or can be performed on both indenters at the same time.

[0014] In the structure shown, the film or foil 7 extending at the bottom along the plastic layer 5 may comprise a copper foil, to wh...

Abstract

The present invention relates to an extrusion ram of a lamination press, the extrusion ram comprising an upper ram and a bottom ram, wherein the upper ram and / or the bottom ram comprises a heatable pressure surface for Heat is supplied to the material to be extruded and at least the extrusion surfaces of the upper and / or bottom extrusion rams comprise at least part of a heat resistant plastic material.

Description

technical field [0001] The present invention relates to an extrusion ram of a lamination press, the extrusion ram comprising an upper ram and a bottom ram, wherein the upper ram and / or the bottom ram comprises a heatable pressure surface for applying pressure to the The extruded material is heated. Background technique [0002] Extrusion heads of this type are known from DE3539990A1 or DE8518808U1. One use of extrusion rams of this type is in lamination presses for the manufacture of laminated films, as described in EP 656 310 B1 or EP 775 054 B1. Laminated films of this type comprise at least one layer of metal foil and at least one layer of plastic film. They are used, for example, to produce conductive strips for circuit boards on which microchips are mounted. Modules produced by these devices are used, for example, in so-called smart cards, such as credit or telephone cards, flip-chip cards, semiconductor carriers or circuit substrates. [0003] The films or foils to...
