Definitions
- the present invention relates to a method for producing a circuit board and a molded part for use in this method.
- the conducting wires or conductor elements are positioned on a copper foil and welded to it, then pressed with insulating material before a conductor structure with conductor tracks and connection points is worked out of the copper foil.
- the object of the present invention is to simplify the production of printed circuit boards, in particular with a large number of segments, to save insulating material and thereby also to reduce the height of the printed circuit board, among other things to improve heat management on printed circuit boards much more efficiently.
- the object of the invention is achieved by the method according to claim 1 and the molded part according to claim 6.
- Step A Provision of an electrically conductive molded part with at least two segments which are connected in one piece (along a parting line) via material webs.
- Step B embedding the segments in insulating material to form at least one printed circuit board substrate.
- Step C Attaching a circuit pattern to the circuit board substrate to form the circuit board.
- Step D Release of the one-piece connection of the segments by cutting through the material webs.
- slot-shaped perforations are introduced into the molded part along a perforation line, for example.
- the segments correspond, for example, to the conductor wires according to patent application EP 1 842 402 and/or to the molded parts according to patent application DE 10 2011 102 484, the contents of which are incorporated herein by reference. Basically, little material should be removed when forming the segments, since the required processing time may also increase with increasing segmentation.
- the segmentation of the molded part is intended to create a parting line which is preferably completely filled with insulating material in the final state of the printed circuit board.
- the separating gap between the segments should be at least wide enough to prevent electrical breakdown through the separating gap due to the insulating material to be inserted.
- a minimum width of approx. 200 ⁇ m has proven to be advantageous for the parting line.
- the material deficit can be easily compensated. If the parting line is larger, channel-shaped indentations along the parting line could appear on the surface of the printed circuit board and lead to delamination, which should be avoided if possible. A maximum width of the perforation line or separating gap of approx. 2000 ⁇ m seems sensible.
- the printed circuit board substrate is coated with a copper foil, for example, from which conductor tracks and connection points are subsequently worked out, for example using an etching process.
- prefabricated line wires and pads can also be attached to the printed circuit board substrate as a conductor structure.
- the one-piece connection of the segments is released after the conductor structure has been attached, in that the material webs are severed.
- the conductor structure can be positioned particularly precisely in relation to the embedded segments. By embedding them in the insulating material, the positions of the segments relative to one another are fixed and remain so even after the material webs have been severed aligned.
- the phrase "webs of material" in the plural is also intended to include a single web of material in the singular.
- the invention also promotes the minimization of the amount of insulating material in the production of the printed circuit board, which results in several advantages: on the one hand, material costs are saved and, on the other hand, the thickness or overall height of the printed circuit board is reduced.
- the less insulating material used the thinner the circuit board.
- the insulating material is not only electrically insulating, but also thermally insulating, so that reducing the amount of insulating material also improves the thermal management of the circuit board.
- steps A to D are preferably, but not necessarily, carried out in the order given. As indicated below, the steps and partial steps of the method can also be carried out, at least in part, in a different order.
- step A has at least one of the following sub-steps, with the sub-steps preferably, but not necessarily, being carried out in the order given:
- the reference mark can be, for example, a character, a symbol, a cross or an opening in the molded part. It is important that this reference mark is clearly defined.
- the reference marking is used to determine a coordinate system on the molded part, so that positions on the molded part can be clearly determined using the reference marking. This is particularly advantageous for the positioning of the later conductor structure in relation to the segments and for the later cutting through of the material webs. After embedding the molded part in insulating material, the parting line or the material web is usually covered with insulating material and is not visible. bar.
- the positions of the material webs must be known exactly in order to be able to cut through them in a targeted manner.
- the conductor structure of the printed circuit board can be defined or formed in a precise position, so that the material webs, which must be accessible for the appropriate tool for later cutting, are not covered by the conductor structure or made inaccessible in some other way.
- the reference marking is preferably machine-readable or optically recognizable with an optical device.
- - A-3 Alignment of the molded part (e.g. in relation to a press setup) using at least one reference mark on the molded part. This makes it easier to process the molded part in the subsequent processing steps.
- A-4-1 Forming a self-contained perforation line around the printed circuit board section, so that the printed circuit board section within the perforation line is connected in one piece to a surrounding edge area outside the perforation line only via isolated material webs, the self-contained perforation line preferably having a polygonal shape.
- the printed circuit board section can be easily separated from the molded part along the self-contained perforation line, preferably after the printed circuit board has been completed.
- the polygonal shape makes it easier to separate the circuit board section from the surrounding material.
- A-4-2 forming at least one open (i.e. not closed) or closed perforation line for dividing the printed circuit board section into the segments, this open or closed perforation line preferably starting at an edge of the printed circuit board section, particularly preferably at a perforation line enclosing the printed circuit board section and/or ends.
- this perforation lines any segments can be formed within the circuit board section.
- a self-contained perforation line it is also possible to form a printed circuit board segment within another printed circuit board segment.
- A-4-3 Forming the at least one perforation line with preferably uniform
- Width preferably a width in the range of 200 to 2000 pm, preferably such that slit-shaped perforations are spaced apart along the perforation line through the webs of material.
- the perforation line forms the later parting line between the segments, which is ideally completely filled with insulating material when the printed circuit board is finished.
- the webs of material, measured along the perforation line are approximately 500 ⁇ m or 0.5 mm wide, for example.
- the distance between two webs of material along the perforation line is, for example, approx. 50 mm, i. H. hundred times the width of the material webs. In this example, about 99% of the material of the molded part has been removed along the perforation line.
- - A-4-5 Forming a plurality of identical or different printed circuit board sections in the molded part, preferably such that the printed circuit board sections are distributed in rows and columns in a matrix over the molded part.
- the area of the molded part can be ideally used to form the largest possible number of printed circuit board sections.
- - A-5 forming at least one opening in the molded part, preferably in the area of at least one printed circuit board segment, preferably within a self-contained parting line.
- step B includes at least one of the following sub-steps, with the sub-steps preferably, but not necessarily, being performed in the order listed:
- B-1 Providing the insulating material in a moldable state, preferably as a flexible planar element, preferably as a prepreg (resin-impregnated fiber mat), particularly preferably with a size tailored to the molded part.
- An insulating material mat can have a corresponding reference marking, which is brought to coincide with the reference marking of the molded part, for example. This ensures that the insulating mat is optimally positioned in relation to the molded part.
- B-2 Application of the insulating material to one side or to both sides of the molded part, preferably in such a way that the insulating material covers the surface of the respective side of the molded part, preferably with a uniform layer thickness. This technology makes it particularly easy to embed the molded part in insulating material.
- B-3 Introduction of the insulating material between the segments of the molded part, preferably by pressing the insulating material with the molded part, preferably in such a way that the insulating material partially or completely fills the gap between the (material webs and/or) segments, particularly preferably in such a way that on both sides layers of insulating material arranged in the molded part are connected in one piece by the insulating material.
- each circuit board section is also embedded in insulating material so that the circuit board section is completely surrounded by insulating material on all sides, with the exception of the material webs.
- step C comprises at least one of the following sub-steps, which sub-steps are preferably, but not necessarily, carried out in the order given:
- C-1 Provision of an electrically conductive surface element, preferably made of metal, preferably made of copper, particularly preferably as a foil, very particularly preferably with a size tailored to the molded part.
- the copper foil has a thickness in the range from 15 ⁇ m to 110 ⁇ m, for example.
- step C-2 Application of an electrically conductive surface element to one side or to both sides of the circuit board substrate, preferably in such a way that the electrically conductive surface element covers the respective side of the circuit board substrate, preferably with a uniform layer thickness. This step can already take place in connection with step C, e.g. during step C3.
- C-3 Positioning of the conductor structure, which preferably has conductor tracks and/or connection points, on the printed circuit board substrate depending on at least one reference marking of the molded part, preferably in such a way that the conductor structure is arranged offset to the material webs when projected onto the plane of extension of the molded part and the Material webs not covered.
- the phrase "conductor tracks” and/or “connection points” and/or “material lands” in the plural is also intended to include a single track, connection point or a single material ridge.
- Conductor tracks and connection points do not necessarily have to be etched out of a copper foil. It is also possible to apply conductor tracks and connection points from prefabricated components to the printed circuit board substrate. The positioning of these components is made easier by the reference mark.
- C-4 Working out the conductor structure, which preferably has conductor tracks and/or connection points for electronic components, from the electrically conductive surface element, preferably by removing material, preferably by etching.
- the positions of the conductor tracks and/or connection points are preferably defined in relation to the reference marking.
- step D Connecting the conductor structure to at least one printed circuit board segment, preferably by means of contacts, preferably by means of through-plating.
- a connector to be introduced later can also ensure the connection to the printed circuit board segment without being connected to a conductor structure. It can be advantageous if step D has at least one of the following sub-steps, with the sub-steps preferably, but not necessarily, being carried out in the order given:
- D-2 Alignment of the tool for cutting through the material webs to the printed circuit board depending on at least one reference mark on the molded part. If, for example, the material ridges are covered by insulating material, the positions of the material ridges cannot be seen with the naked eye, but must be determined in some other way. The position of the material webs can be precisely determined using the reference mark. By reading in the reference mark and passing on the information to a tool control, the tool can be guided exactly to the position of a material web to be cut in order to release the one-piece connection of the segments in a targeted manner.
- D-3 Separation of the material webs by material removal, preferably by drilling or milling, preferably perpendicular to the plane of extension of the molded part. Ideally, the entire web of material is removed when the material is cut, minimizing the risk of electrical breakdown at the location of the previous web of material. In this way, two slot-shaped perforations (filled with insulating material), which were previously separated by the material web, are connected to form a continuous parting line.
- D-4 Filling the separating points of the material webs with insulating material, preferably in such a way that a separating gap between the segments is completely filled with insulating material. This minimizes the risk of electrical breakdown between segments across the parting line.
- a circuit board consisting of several levels can also be produced using this method.
- the mold parts can be arranged parallel to one another.
- the conductor structure can also extend over several levels.
- a further aspect of the present invention relates to a molded part for producing a printed circuit board, preferably using the method according to one of the preceding statements, comprising two segments which are connected in one piece only via isolated material webs.
- This molded part can be prefabricated as a mass component and made available for the production of a large number of printed circuit boards in series production.
- the molded part has slit-like perforations along a perforation line, which are interrupted by the material webs.
- a further aspect of the present invention relates to a printed circuit board arrangement, comprising at least two printed circuit boards and at least one molded part according to one of the two preceding embodiments, each segment of the molded part being connected to the at least two printed circuit boards and the segments of the molded part being electrically insulated from one another with the material webs being severed .
- the segments can be used to create articulated or angled and electrically conductive connections between the printed circuit boards in a particularly simple manner.
- a molded part is preferably understood to mean a flat, plate-shaped component, in particular made of an electrically conductive solid material such as metal, in particular copper.
- the molded part preferably has no irregularities or interruptions within its outline.
- the term "conductor structure” is understood to mean everything that can bring about an electrically conductive connection to at least one of the segments through the insulating material.

- a printed circuit board LP is produced in a layered construction starting from an electrically conductive molded part 1 in the form of a rectangular copper plate with a thickness in the range of, for example, 200-1000 ⁇ m.
- the molded part 1 is made available for subsequent processing.
- two segments 2a, 2b of a printed circuit board section 2 are formed by introducing corresponding perforation lines P into the molded part 1.
- the circuit board section 2 is formed within a self-contained, polygonal perforation line P with eight corners.
- slit-shaped openings with a preferably constant width in the range from about 200 to 2000 ⁇ m are made in the molded part 1 by appropriate removal of material, so that the segments 2a, 2b remain connected in one piece only via isolated material webs M.
- the entire circuit board section 2 is connected to the surrounding edge area of the molded part 1, in which a reference marking R is located, via the self-contained perforation line P.
- the reference mark R is used to determine the position on the surface of the molded part 1 and is, for example, an opening with which the molded part 1 is placed on a pin.
- a number of reference markings R can be provided on the molded part 1 .
- the molded part 1 is embedded at least in sections in insulating material 3 in step B of the method according to the invention.
- the resulting intermediate product is referred to as the printed circuit board substrate LS.
- Two resin-impregnated fiber mats (prepreg) 3, ideally with a shape and size tailored to the molded part 1, are applied to the molded part 1 on the top and bottom. These resin-impregnated fiber mats 3 are pressed with the molded part 1 in such a way that the flowable resin penetrates into the perforations along the perforation line P and completely penetrates the gaps between the webs of material M.
- the electrically conductive surface element 4, from which the conductor structure is worked out in step C can also be simultaneously connected to the insulating material by pressing.
- a sandwich-like layered composite as shown in FIG. 3, consisting of the molded part 1, two insulating material mats 3 and two copper foils 4, is pressed together.
- the hardening of the insulating material 3 fixes the positions and orientations of the segments 2a, 2b relative to one another, so that they are retained later—even after the material webs M have been severed.
- step C of the method according to the invention the conductor structure 4a, 4b is attached to the printed circuit board substrate LS.
- this step includes the attachment of at least one copper foil 4 as an electrically conductive surface element to the printed circuit board substrate LS, for example a copper foil 4 each on the upper side and on the underside of the printed circuit board substrate LS.
- This is preferably already done in step B, so that the copper foils 4 are pressed with the molded part 1 and the insulating material 3 arranged between the copper foil 4 and the molded part 1 to form a composite layer or material.
- step D for example in the etching process, a conductor structure with conductor tracks 4a and connection points 4b is worked out.
- the conductor tracks 4a are connected to the segments 2a, 2b via contacts 5 (eg vias or laser vias (left) or through contacts (right)).
- the material webs M which connect the segments 2a, 2b in one piece, are severed by removing material. This is accomplished, for example, with a drill that is guided to the corresponding positions of the material webs M using the reference marking R.
- the entire material of the material webs M is preferably removed over the entire length, which corresponds to the width of the previous perforation line P and which now forms a parting line.
- the separation point is filled with insulating material 3, so that the risk of electrical breakdown between the segments 2a, 2b—in particular at the points of the former material webs M—is minimized. Whether the point of separation is filled with insulating material 3 or not can be determined primarily as a function of the dielectric strength of the printed circuit board or the insulating material.
- the finished printed circuit board LP is then separated from the surrounding area along the self-contained perforation line P, which surrounds the printed circuit board section 2 and the segments 2a, 2b.
- the second embodiment of the present invention which will be described below with reference to FIGS. 5 and 6, is essentially based on the first embodiment. Identical features are given identical reference numbers, with the relevant differences being explained below.
- the shaped part 1 designed as a rectangular copper plate comprises a total of four largely identical printed circuit board sections 2 which are arranged in a matrix in two columns and two rows over the surface of the shaped part 1 .
- An octagonal, self-contained perforation line P surrounds each of the four printed circuit board sections 2.
- Each printed circuit board section 2 within the circumferential perforation line P is connected in one piece via the isolated material webs M to a surrounding edge area of the molded part 1, on which various reference markings R are located.
- a plurality of segments 2a-i are formed by further perforation lines P.
- the subsequent conductor structure 4a, 4b with connection points 4b and conductor tracks 4a extending between them is drawn in by dashed lines in each printed circuit board section 2. It can be seen here that the conductor structure 4a, 4b does not cover the material webs M when projected onto the extension plane of the molded part 1. Consequently, the webs of material M are accessible for later processing.
- the segments 2a-i and perforation lines P preferably completely fill the respective printed circuit board section 2 in terms of surface area, as shown in the two printed circuit board sections 2 in the left-hand half of FIG.
- a printed circuit board section 2 or at least one printed circuit board segment 2a-i to have at least one opening 2j, 2k, as is shown in the two printed circuit board sections 2 in the right half of FIG.
- the two printed circuit board sections 2 in the right half of FIG. 5 have two openings 2j, 2k in the printed circuit board segment 2a instead of the segments 2h, 2i.
- the material of the molded part 1 corresponding to the areas of the openings 2j, 2k is completely severed and removed from the molded part 1 in step B along a closed parting line T in each case.
- a preferably hardened insulating material 3 is introduced into each opening 2j, 2k in order ideally to completely fill up the openings 2j, 2k and later to form an electrically non-conductive printed circuit board segment.
- insulating material 3 makes sense because when the molded part 1 is then pressed with insulating material in the form of resin-impregnated fiber mats (prepreg), the free resin of the insulating material 3 is only available or flowable to a limited extent, and serves primarily to fill the perforations along the perforation line P.
- An almost identical height of the insulating material plates placed in the openings 2j, 2k in relation to the height of the molded part 1 is preferred, so that the upper and lower sides of the insulating material 3 are flush with the upper and lower sides of the molded part 1.
- this molded part 1 (still without the conductor structure shown purely for purposes of illustration) is embedded in insulating material 3 and then provided with a corresponding conductor structure 4a, 4b at the positions shown in FIG.
- the material webs M are severed along the perforation lines P and the boreholes that are produced in the process are filled with insulating material 3, if necessary.
- each printed circuit board LP is separated from the composite material along the outer perforation line P surrounding the printed circuit board section 2 .
- the number and the shapes of the printed circuit board sections 2 and segments 2a-i as well as reference marks R can be changed at will.
- the third exemplary embodiment of the present invention which is described below with reference to FIGS. 7 to 10, is essentially based on the first and second exemplary embodiments. Identical features are given identical reference numbers, with the relevant differences being explained below.
- each segment 2a, 2b, 2c is connected to two printed circuit board substrates LS or printed circuit boards LP, so that the respective segment 2a, 2b, 2c forms an articulated or angled connection between two or more printed circuit boards LP or substrates LS.
- the shaped part 1 is here an approximately ladder-shaped element which is machined from a flat, rectangular copper plate (FIG. 7a) in step A of the method according to the invention.
- the horizontally extending sections in Fig. 7b correspond to the segments 2a, 2b, 2c, the vertically extending sections, which connect the segments 2a, 2b, 2c, correspond to the material webs M.
- step B the molded part 1 is embedded in insulating material 3 to form printed circuit board substrates LS.
- Each segment 2a, 2b extends over almost half of its length in a first printed circuit board substrate LS and over almost half of its length in a second printed circuit board substrate LS.
- step C conductor structures for forming the circuit board LP are produced on one or more of these circuit board substrates LS.
- the molded part 1 is connected to an electrically conductive surface element such as a copper foil, or via connecting means sections, as is known from DE 10 2018 203 715.
- the conductor tracks 4a and the connection points 4b for contacting the segments 2a, 2b, 2c are worked out of this electrically conductive surface element, e.g. by etching from the electrically conductive surface element.
- step D the material webs M are severed so that the one-piece connections between the parallel segments 2a, 2b, 2c are released.
