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

[0012] The extrusion head 1 is arranged in a lamination press, which is not shown in the figures but is known to experts in the field from DE 85 18 808 U1. 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.

[0013] In the structure shown, the film or foil 7 extending at the bottom along the plastic layer 5 may comprise a copper foil, t...

Abstract

The invention relates to press ram for laminating press. In a press of a type in which an upper ram and a lower ram which are press rams for a laminating press are provided and the upper ram and / or the lower ram have a heatable pressing surface for supplying heat to a press material, the pressing surfaces of at least the upper ram and / or the lower ram are at least partially formed of heat-resistant plastics.

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 DE 35 39 990 A1 or DE 85 18 808 U1. 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 ...
