Definitions
- the invention relates to a method for producing vias according to the preamble of claim 1.
- plated-through holes in general and in particular micro-plated-through holes in a small space with a pad diameter of less than 200 ⁇ m are a problem ⁇ m and a pad diameter of 250 to 300 ⁇ m.
- document WO 2004/015161 A1 discloses a method and an arrangement for processing carrier material by heavy ion irradiation and subsequent etching process, which are used to roughen the surface of a carrier means of a printed circuit board structure or of the carrier material of the printed circuit board structure, so that a subsequently applied copper layer holds securely on the appropriately machined surface of the carrier or the carrier material.
- the roughening of the surface is particularly important if the copper layer is applied to the carrier or carrier material without adhesive and if the carrier or carrier material is plastic, such as polyimide.
- Polyimide (PI) is used for high-quality printed circuit board structures that are bendable, that is, flexible.
- Other examples of such carriers are polyethylene naphthalate (PEN) or polyester (PET).
- PEN polyethylene naphthalate
- PET polyester
- CEM1, FR2 or FR4 can be used as the carrier.
- the object of the present invention is therefore to specify a method for producing printed circuit board structures of the type mentioned at the outset, which has a simplified production process, which enables the production of very small vias, and which can also be used in printed circuit board structures which are produced without adhesive and are flexible.
- At least one hole is produced at a point in the later printed circuit board structure intended for through-plating using a hole production method for producing at least one hole in each case at a respective point.
- the method of drilling, lasering or shooting heavy ions can be used as the hole production method.
- the latter has the particular advantage that the smallest vias can be implemented.
- the fabricated holes can be etched to a desired size. If the hole production process used means that more than a single hole is created at the same time next to one another, as is possible, for example, when bombarding heavy ions, holes that are close together are melted together to form a single hole of the desired size. Such an end hole then has, for example, a hole diameter of 1 to 3 ⁇ m, which is currently the possible smallest hole for a via.
- the thickness of the copper cladding was minimal. The finest conductor track structures can thus be produced with these copper claddings.
- the small diameters of the vias have the advantage that they are completely filled with copper when the electrical vias are being made. This is advantageous for a possible maximum current density that can flow through these plated-through holes and is advantageous with regard to a flat surface of the carrier.
- the through-contacts therefore do not have to be filled in a further process step in order to obtain a flat surface.
- plated-through holes are very small, plated-through holes can be provided accordingly on a predetermined area of the carrier means or the printed circuit board structure. This is particularly “advantageous if the circuit board structure is to be used, for example, for displays in which it is necessary to be able to control a large number of control points, and this in increasing numbers.
- the heavy ion bombardment can be used as the hole production process. As already mentioned above, this enables the smallest realizing stanchions. If such small vias are not required, the holes can also be created using a laser method. If the plated-through holes can be coarser, the holes can also be made using a conventional drilling method.
- Another advantage is the possibility of using flexible materials such as polyimide as a carrier, because it can be used to produce flexible printed circuit boards. Even with the smallest vias and the finest conductor structures.
- the process step of roughening the surface of the carrier means to ensure the adhesive strength with respect to the copper cladding does not have to be carried out in advance if the bombardment method with the heavy ions is selected for hole formation for the plated-through holes.
- the bombardment method can be used in addition to the production of the holes for the plated-through holes with appropriate control of the heavy ion radiation at the same time for roughening the surfaces of the carrier.
- the heavy ion radiation is set accordingly less intensely. At points where through holes are desired, a correspondingly increased bombardment is carried out so that the heavy ions penetrate through the entire thickness of the carrier at these points. This saves costs and production times.
- the possibility of roughening the surfaces of the carrier means has the advantage that the circuit board structure can be realized without adhesive.
