Abstract

To produce a flat electronic arrangement (20), a carrier strip is provided as a film (10), the longitudinal direction L of which extends in a first direction X. The carrier strip (10) is equipped with electrical components (11). The carrier strip (10) is then folded along fold lines (12a, 12b) in the direction F1 and in the direction F2. The fold lines (12a, 12b) are arranged in one or more fold areas (13) of the carrier strip (10) in such a way that when folding several sections (14a, 14b, 14c) of the carrier strip (10), which are arranged one after the other in its longitudinal direction L. are positioned next to one another in a second direction Y which is perpendicular to the first direction X. The result is a large-area electronics arrangement which, for example, forms a very flat and flexible antenna arrangement.

Description

The invention relates to a method for producing a flat electronic arrangement. The invention also relates to an electronic arrangement which is flat, and an aircraft with such an electronic arrangement.

In various areas of technology, it is necessary for a large number of electrical and electronic components to be arranged in a flat design on a carrier structure. The electrical or electronic components there form one or more electronic units. It is often necessary to design the support structure with the electronic unit or the entire electronic arrangement over a very large area.

The electrical components or components attached to the support structure can be, for example, antennas, antenna units, chips with electronic or microelectronic circuits, sensors, electrical connections, conductor structures, etc., as well as other electrical or electronic components

In the manufacture of flexible circuit boards and printed circuits, such electronic units are often printed on a film. For example, the R2R process or roll-to-roll process is used. In this technology, the film serves as a substrate for the electrical and electronic components that are arranged on the film or in the film, for example by printing the film and / or embedding it in the film. An electrical connection between the components can also be contained on or in the film, so that, for. B. no cables are required.

The film can be very long, its length z. B. can be a few meters up to a kilometer and more. In contrast, the width of the film is very limited, since only a small film width can be handled during the production of the film, which is a maximum of approx. 30 cm to 60 cm. The film is z. B. unrolled from a roll.

Such a film can be arranged on a structure. However, for certain applications it may be necessary for the width of the film to be greater than the width of the film strip that is made available for further processing. For example, the maximum width of the provided film can be 30 cm, while a width of 90 cm is required for a specific application.

A known solution to this problem provides that a long film with a number of different segments is produced and the film is then cut into appropriate strips. The individual film strips are then arranged next to one another strip-by-strip on a structure in order to achieve a larger area with a larger width.

The 2a and 2 B show this known method. In 2a is a relatively long and narrow film 60 shown, which is available for the further procedure. The foil 60 is in different segments 60a , 60b , 60c assigned.

The 2 B shows the slide 60 after which it was cut. The individual separate segments 60a , 60b , 60c are now side by side on one structure 65 arranged.

In many cases it is necessary to have electrical connections between the individual strips or segments 60a , 60b , 60c produce what z. B. by arranging additional bridging foils. However, this has the disadvantage that such an arrangement is very expensive and difficult to manufacture. There may also be other disadvantages, e.g. B. when high frequency signals are to be transmitted.

In addition to the known roll-to-roll or R2R process, another technology is known in which foils are processed on the basis of a foil sheet. Such film sheets can have a size of, for example, approximately 40 cm × 40 cm. However, certain applications require a longer strip of film. In this case, the sheet of film is cut and folded into a long strip.

The 3a , 3b and 3c show this further known method. 3a shows a rectangular slide 70 which is made available for further processing.

3b shows the slide 70 after incisions on two opposite sides 71 into the slide 70 were introduced. This creates an incision on either side of each 71 adjacent strip elements 72a , 72b that can be folded in opposite directions.

3c shows a section of the slide 70 in the cut and folded state. By folding at the end of each incision 71 are the strip elements 72a , 72b lined up lengthways.

The pamphlet DE 10 2015 113 928 A1 shows an object which has an electronic unit and conductor structures on a carrier structure. The carrier structure has a carrier layer which is a plastic film.

DE 10 2016 209 495 A1 describes an electrical arrangement with a carrier for electrical components and a method for their production. A strip-shaped carrier is provided with a gap along its length, so that a section of the strip-shaped carrier is located on both sides of the gap. Now the pieces are folded so that they extend in opposite directions or also form an angle to one another.

1 shows an electronic arrangement 20th according to a preferred embodiment of the invention. The electronics arrangement 20th is formed from a film and includes electrical components 11 that form an electronic unit.

The electronics arrangement 20th is made by an elongated, relatively narrow carrier strip 10f formed, the electrical components as a substrate in the form of a film or plastic film 11 stops and on fold lines 12a , 12b is folded. The longitudinal direction L. of the carrier strip 10f extends in the X direction.

By folding the carrier strip 10f at the fold lines 12a , 12b are originally sections arranged one after the other 14a , 14b , 14c of the carrier strip 10f in the electronics arrangement 20th arranged side by side. The arrangement of the adjacent sections extends here 14a , 14b , 14c of the carrier strip 10f in the Y direction, that is, perpendicular to the longitudinal direction L. of the carrier strip 10f or in the direction of width B. of the carrier strip 10f

The electronics arrangement 20th is flat. It extends in the XY plane. It thus forms a printed circuit board that is flat. Since it is flexible, it can be curved or applied to a curved or uneven structure, depending on the application.

On the carrier strip 10f are folding areas 13 designed in which two layers of the carrier strip 10f lie on top of each other. The folding areas 13 are located on opposite sides of the electronics assembly 20th , in the figure above and below, and each connect two of the adjacent sections 14a , 14b , 14c of the carrier strip 10f . In the folding areas 13 is the Carrier strip 10f or the film that makes up the carrier strip 10f is formed, designed thinner than in the other areas or in the adjacent sections 14a , 14b , 14c of the carrier strip 10f .

In the foil or electronics arrangement 20th that form a circuit board are each two adjacent sections 14a , 14b or. 14b , 14c of the carrier strip 10f aligned parallel to each other. The sections border 14a , 14b , 14c of the carrier strip 10f with their lateral edges or longitudinal edges against one another. The sections 14a , 14b , 14c can in this way adjoin one another in a form-fitting manner, so that they form a continuous or uninterrupted surface.

For a better representation, possible distances or inaccuracies between the sections are shown in the figure 14a , 14b , 14c shown enlarged. The figure is a schematic, sketch-like representation showing the essentially parallel course of the sections 14a , 14b , 14c and its side edges as well as the shape of the electronic arrangement and its parts, as it is described here, shows in principle and should also be understood as such.

Depending on the application, the carrier strip 10f also be folded so that the individual sections 14a , 14b , 14c are arranged laterally spaced from each other. It is also possible that the adjacent sections 14a , 14b , 14c are arranged laterally overlapping or partially overlapping.

The areas shown hatched in the figure show the course of an underlying section of the carrier strip 10f that by folding at the fold line 12b is covered.

The folding directions F1 and F2 at the fold lines 12a or. 12b are indicated in the figure by curved arrows. The first fold line 12a runs obliquely at an angle α of 45 ° to the longitudinal direction L. of the carrier strip 10f . After the first folding in the folding direction F1 is in the folding area 13 the underside of the carrier strip 10f arranged lying on top.

The second fold line 12b also runs obliquely at an angle of 45 ° to the longitudinal direction L. of the carrier strip 10f . By folding the carrier strip a second time in the folding direction F2 is in the folding area 13 the ones with numbers 1 to 6th marked upper side of the carrier strip 10f again arranged lying on top. This is how all the adjacent sections are 14a , 14b , 14c arranged so that the same side of the carrier strip 10f in all sections above.

Every fold F1 , F2 takes place at 180 degrees, which means the carrier strip is on the fold lines 12a , 12b in the directions F1 , F2 folded down.

The individual sections 14a , 14b , 14c of the carrier strip 10f are with a lateral offset V arranged to each other, whichever is the width B. of the carrier strip 10f corresponds. The sections 14a , 14b , 14c border each other.

The fold lines 12a , 12b border each other with one of their two ends and form an angle β of 90 ° to each other.

The longitudinal direction L. of the carrier strip 10f runs in the adjacent sections 14a , 14b or. 14b , 14c each in the opposite direction. This is in the longitudinal direction L. of the carrier strip 10f sequentially arranged areas 1-2, 4-3, 5-6 arranged side by side by folding. The identification of the successive areas of the carrier element by numbers is chosen so that after folding the odd-numbered areas 1, 3, 5 or the even-numbered areas 2, 4, 6 lie next to one another in the Y direction.

The ones from the folded carrier strip 10f formed electronics assembly 20th can vary depending on the number of folding areas 13 by placing any number of sections next to each other 14a , 14b , 14c of the carrier strip 10f extend in any extent in the Y direction. That is, the dimension of the electronics arrangement 20th in the direction of width B. of the relatively narrow carrier strip 10f can be designed in any size. In other words, the originally relatively narrow electronics arrangement in the form of the originally unfolded carrier strip 10 is made by folding along the fold lines 12a , 12b widened.

Furthermore, the dimensions of the electronics arrangement 20th in the X direction or in the longitudinal direction L. of the original carrier strip by choosing the length of the sections 14a , 14b , 14c can be designed as desired. The electronics arrangement 20th can thus extend at the same time in very great length and width.

In the printed circuit board or electronic assembly designed as a film 20th is an electrical connector 15th arranged that through and / or over the entire electronics assembly 20th extends and is electrically contactable at different points. The electrical connector 15th connects the electrical components 11 which is based on the entire, large-area and flexible electronics arrangement 20th are distributed.

That is, the connecting element 15th extends in the longitudinal direction L. through the entire folded backing strip 10f over and / or through its sections 14a , 14b , 14c and the fold lines 12a , 12b . It can be placed anywhere on the electronics assembly 20th be contacted and all electrical elements 11 in the adjacent sections 14a , 14b , 14c electrically connect with each other.

The connecting element 15th is for example a conductor structure with one or more conductor tracks or metallizations.

The foil or electronic assembly 20th is on a structure 31 arranged, which is an auxiliary material in this example, which is also designed as a film.

The alignment of the electronic assembly can 20th or their sub-areas when positioning on the structure 31 or the auxiliary material. This can result in advantages in terms of accuracy and manufacturing or installation costs. The auxiliary material can be, for example, an adhesive layer or adhesive layer.

The electronic assembly arranged on the structure can be attached to a surface.

The structure 31 can also be an outer surface or the outer skin of an aircraft, for example. In this case, the electronics assembly is aligned 20th and / or their sub-areas or sections 14a , 14b , 14c during attachment to the structure 31 or to the aircraft.

The electronics arrangement 20th with their electronic unit 11a by the electrical elements 11 can be formed on the structure 31 for example, can be attached by gluing.

Markings on the foil or electronics arrangement 20th , which are not shown in the figure, allow the exact alignment of the electronic assembly 20th and / or their sections 14a , 14b , 14c if they are on the structure 31 is arranged.

The electrical elements or components 11 that are embedded in the electronics assembly and / or on the electronics assembly 20th are arranged, antennas and antenna elements with different functions and configurations are in the particularly preferred embodiment described here. You are in the electronics assembly 20th integrated and together form, for example, a single flat antenna or antenna unit. For example, there can be 30 to 40 and more different antennas on or in the electronics assembly 20th be arranged. The one through the electronics assembly 20th formed antenna or antenna arrangement can work in different frequency ranges.

Furthermore, as electrical components 11 a very large number of electronic chips and other electronic components, including antenna elements, for example, on the large-area film or the electronic arrangement 20th arranged and / or in the film or electronic assembly 20th embedded.

The electronics assembly or foil 20th is still very thin. In this exemplary embodiment, their thickness is only a few millimeters.

Depending on the embodiment, the thickness of the film or the electronic assembly is 20th preferably less than 20mm, particularly preferably less than 10mm, particularly preferably less than 5mm and in certain cases a maximum of 2mm.

Through the electrical connector 15th are all components or electrical components 11 electrically connected to each other. For this purpose are used as a connecting element 15th different metallization layers in the foil or electronic assembly 20th contain, which interconnect the electrical components 11 enable.

The electronics arrangement 20th , which in this example forms an antenna device, has a diameter or a length or width in the range of, for example, one to three meters.

The following is based on the 1 and 4th an example of a method for manufacturing an electronic assembly 20th described according to the invention.

First is a carrier strip 10 provided that the electrical components 11 includes. The carrier strip 10 has a relatively great length and a relatively small width. It is flat, preferably as a film. Its longitudinal direction L. extends in a first direction X (please refer 4th ).

The components 11 are designed as described above and are in the carrier strip 10 embedded and / or on the carrier strip 10 attached. Furthermore, the connecting element described above is in and / or on the carrier strip 15th arranged so that it extends through the carrier strip 10 in its longitudinal direction L. extends,

Between every two sections 14a , 14b or. 14b , 14c of the carrier strip 10 becomes a folding area 13 arranged. Any folding area 13 is in 4th represented by a hatched area.

The connecting element 15th runs through the sections 14a , 14b , 14c of the carrier strip 10 and through the folding areas in between 13 .

How out 1 The next step is to use the carrier strip that is available 10 along the fold lines 12a , 12b folded twice. This will be the fold lines 12a , 12b in several folding areas 13 of the carrier strip 10 arranged so that when folding multiple sections 14a , 14b , 14c of the carrier strip 10 in a second direction Y positioned next to each other. The second direction or Y direction runs perpendicular to the first direction or X direction.

To the sections 14a , 14b , 14c of the carrier strip 10 to be arranged side by side by folding twice in each case, the fold lines 12a , 12b obliquely to the longitudinal direction L. of the carrier strip 10 arranged or designed to run. To the different sections 14a , 14b , 14c to be arranged parallel to each other, the two fold lines run 12a , 12b at an angle β of 90 ° to each other.

To the lengthways L. on both sides of the folding area 13 adjacent sections 14a , 14b or. 14b , 14c The two fold lines are bordered by the two folds that are adjacent to one another or to place them edge-to-edge next to one another 12a , 12b each with one end to the other.

In other configurations, depending on the intended application, it is also possible to use the fold lines 12a , 12b to be arranged so that their two ends are spaced apart. This creates a space between the sections 14a , 14b or. 14b , 14c when they are placed side by side by folding.

• Ausgehend von dem sich in einer Ebene in Längsrichtung L erstreckenden Trägerstreifen 10 erfolgt zunächst das erste Falten an der Faltlinie 12a. Dabei wird der an den Abschnitt 14a angrenzende Faltbereich 13 einmal in Richtung F1 gefaltet, sodass seine Unterseite oben liegt und der restliche Trägerstreifen sich in die y-Richtung erstreckt. Anschließend erfolgt das zweite Falten in Richtung F2 an der Faltlinie 12b, wobei der sich an die Faltlinie 12b anschließende Faltbereich 13 wieder in die X-Richtung, d.h. in die Längsrichtung L des ursprünglichen Trägerstreifens 10 erstreckt. Durch das Umklappen des Trägerstreifens 10 an beiden Faltabschnitten 12a, 12b ist die Oberseite des Trägerstreifens 10 in dem nächsten Abschnitt 12b wieder oben gelegen.

The double folding in the different folding areas 13 takes place in the following way:

• Starting from which is in a plane in the longitudinal direction L. extending carrier strip 10 the first folding is done on the fold line 12a . This is done by the section 14a adjoining folding area 13 once towards F1 folded so that its bottom is on top and the rest of the carrier strip extends in the y-direction. Then the second folding takes place in the direction F2 at the fold line 12b , being attached to the fold line 12b subsequent folding area 13 again in the X direction, ie in the longitudinal direction L. of the original carrier strip 10 extends. By folding down the carrier strip 10 on both folding sections 12a , 12b is the top of the carrier strip 10 in the next section 12b located upstairs again.

Any number of other folds F1 , F2 take place in a corresponding manner, so that a large number of adjacent sections 14a , 14b , 14c , etc. shows what the electronics assembly 20th as described above (see 1 ).

According to the invention, a long film is produced or provided, which is then folded in such a way that a greater width is achieved. The limitation of the width of carrier strips and in particular of foils with electrical elements, which is in the range from 30 to 60 cm, for example, is thereby overcome. The invention enables a large-area structure with a very large area that is covered with a large-area film, electrical connections being made possible between all structural elements or electrical and electronic components on and / or in the film.

In particular, the invention enables very large and at the same time very thin antenna arrangements in which the various antenna elements are connected to one another with high-frequency connections and / or connections with high data rates. As described above, the flat and flexible electronics or antenna arrangement 20th be fixed positively on curved surfaces. A structure-integrated or structure-conformant antenna or antenna arrangement is thus created which is particularly suitable for attachment to aircraft.

The production of flat electronic arrangements and their attachment to surfaces of structures, such as in particular on the outer skin of an aircraft, is made easier and more cost-effective by the invention, since no connections between the electrical elements then have to be attached in different areas of the foil and different areas of the foil do not more need to be bridged.
