The invention also relates to an apparatus for arranging or aligning an object on a substrate, in particular marking and / or substrate from an object, in particular from at least one light source for irradiating light to at least one marking area of the object to be placed and the object to be placed. And a recording device for recording and selectively evaluating the reflected light from and determining the position of the object and / or modifying the position or alignment of the object based on the reflected light that is recorded and then selectively evaluated, such methods and apparatus It relates to the use of.

While the invention will be described in detail by way of example in particular in terms of fabrication or processing of a printed circuit board, the invention is a method and apparatus for placing or aligning an object on a substrate or in a storage or support device, optionally with different wavelengths. Apparatus and method for recording an object, a substrate supporting an object or reflected light from a support device when irradiated with light, into a recording device and modifying the position or alignment of the object with respect to the substrate as well as the position or alignment of the substrate with respect to the processing machine. It should be noted that this can be applied collectively. Such methods and apparatus can be used in a variety of applications that perform high precision processes or machining, such as, for example, drilling processes, cutting processes, etching processes, and the like. In addition, accurate alignment and placement will be an essential element, for example, in the exposure and insertion process.

In terms of the manufacture or processing of a printed circuit board, for example a drilling process to be carried out, in particular in the case of a laser drilling process, a plurality of bores substantially in the printed circuit board or in a substantially plate-like element which generally comprises a plurality of printed circuit boards. After providing the marking on the printed circuit board or on a plate-shaped element comprising a plurality of printed circuit boards by providing at least two markings to form a hole, the printed circuit board or generally plate-shaped element is transferred to a processing station where In which the bore holes are precisely arranged according to, for example, a computer controlled drilling program, for example connecting individual elements of a printed circuit board, inserting additional elements or For joining different layers of substrate It is known to be used for further processing.

Up to now, this kind of alignment or placement process is to irradiate or apply light, such as a suitably focused bundle of light, onto a printed object, such as a printed circuit board, in the area of the marking or markings, or to a printed circuit board or generally Recording of the reflected light from the substrate to the recording apparatus, and optionally determining the position or alignment of the object to be placed with respect to the substrate when there is a marking from the object to be placed, such as a hole that completely penetrates the object to be placed. And automatic image processing of the recorded reflected light to set or adjust the position or alignment to a specific setting value in order to be able to perform a subsequent processing process such as a drilling process with appropriate precision if necessary.

Such known methods and apparatus in which the reflected light is recorded to determine the position and alignment of the object to be placed are such that the object being placed, in particular a plate-like element comprising a printed circuit board or a plurality of printed circuit boards, has at least partly a reflecting surface. The drawback is that it is difficult or impossible to provide good contrast, for example for bright or white substrates that provide sufficient contrast, in the case where the area surrounding the marking of the object to be placed is a marking or in the form of a full hole. This is because the reflected light or stray light reflected from the reflecting surface of the object to be placed and the reflected light reflected from the marking or the underlying substrate cannot be distinguished with the required precision, which is the arrangement or orientation of the object. Forms the basis for the determination of

In particular, for example, in view of the high precision required for the manufacture or processing of a printed circuit board, for example, taking into account the element having a very small size to be subsequently connected or bonded and the element having a small size to be provided in the element to be applied or the bore hole to be formed. When using the method and the apparatus, it is anticipated that a substantial part of the object will not be processed correspondingly precisely, in particular because it has not been adjusted sufficiently precisely, and therefore failure will be expected. Moreover, significant misalignment or misregistration will result in manufacturing interruption since such control mechanisms would normally cause manufacturing interruptions.

The present invention is simplified and easy to solve the above-mentioned problems of the methods and apparatus of the kind defined at the outset, and in particular to reduce the parts of the object to be treated, i.e., the defective parts, which do not meet the respective quality requirements during the manufacture or processing of the object. It is an object to further develop a method and apparatus of the kind defined at the outset so that an object can be placed or aligned with respect to a substrate with improved accuracy by recording and selective evaluation of a reflected light.

In order to achieve these objectives, the kind of method defined at the outset is achieved by using light emitting materials in particular in the marking area, whereby the light used for irradiation is converted into light of different wavelengths, and the light of the different wavelengths is recorded on the recording apparatus and selectively evaluated.

In contrast to known methods in which light reflected directly from an object, in particular marking or substrate, is recorded and optionally evaluated, according to the invention, the wavelength of the light used for irradiation, in particular by using a luminescent material, is a light having a different or changed wavelength. Or in general due to the fact that the conversion to electromagnetic radiation is carried out, and then the light with this changed wavelength is simply recorded on the recording device and selectively evaluated, relative to the substrate by an alternatively simplified recording and evaluation method or For example around markings with wavelengths of light originally used to irradiate objects and markings, such that determining the actual position or alignment of at least one marking of an object to be aligned or aligned to a substrate or storage or support device is performed. Reflected light from objects in the area is not recorded on the recording device. Is guaranteed.

By converting the light used to irradiate the object, in particular the marking area, into a light of a different wavelength, in particular using a material of luminescence, ie fluorescence or phosphorescence, the accuracy of alignment and placement will be improved, thereby improving and more precisely Depending on the placement and alignment, it becomes possible to further process the object to be processed with improved precision, thereby reducing the inaccurate placement or alignment of the object to be placed or actual so that the portion of the processing object that does not meet each quality requirement and causes rejection is reduced. Unstable processing caused by incorrect determination of position or alignment will be considerably reduced or entirely avoided. It is also possible to avoid or eliminate the problems involved in downtime due to very incorrect alignment or misadjustment. Furthermore, by the method according to the invention, the time required for alignment or placement will be reduced so that the application of the method according to the invention results in an improvement in efficiency or productivity. Indeed, in the case of the method according to the invention, essentially, the reflected light cannot be introduced into the recording and evaluation device, but the light projected from the at least one light source to the object to be placed or aligned has a different wavelength by luminescence, fluorescence or phosphorescence.

2 is a partial cross-sectional view of the embodiment according to FIG. 1 on an enlarged scale in the marking area of the object to be placed or aligned;
3 is a partial cross-sectional view of a modified embodiment of the device of the invention for carrying out the method of the invention in a view similar to FIG.
FIG. 4 shows another modified embodiment of the device of the invention for carrying out the method of the invention in a view similar to FIG. 2.

1 schematically illustrates an object 1 to be placed or aligned formed by a substantially plate-like element comprising a plurality of printed circuit board elements, for example indicated as approximately two separated into individual printed circuit board elements after processing and completion. Illustrated. The object 1 to be arranged and / or aligned in the embodiment according to FIG. 1 comprises two markings 3 in the form of a complete hole 3, which will be described in more detail with reference to FIG. 2, for example.

The light emitted from the light source 4 is irradiated to the marking or marking 3 region of the plate-like element 1 along the approximately indicated beam path 5, thereby being explained in more detail with reference to the following drawings. Due to the provision of a luminescent material in the marking 3 area, light or generally electromagnetic radiation along the beam path 6 with a changed wavelength for light emitted from the light source 4 through the beam path 5 It is delivered to a recording device, such as a camera, indicated at approximately seven. The camera 7 is arranged with an optical filter 8 on the front, which allows, for example, only light of a changed wavelength along the beam path 6 to enter the recording device or the camera 7, in particular below with reference to the other figures. As will be explained in more detail in, for example, reflected light having a wavelength equal to the wavelength reflected in the area surrounding the marking 3 and emitted from the light source 4 will be prevented from passing through the filter 8.

The recording device 7 is coupled with the evaluation and display device or the unit 10 via the generally indicated connecting line 9, and as a function of the signal received by the recording device 7 in the unit, for example, of the object 1 to be positioned. Evaluation regarding position and / or alignment, in particular automatic image evaluation, is performed.

If misalignment or misalignment of the plate-like object 1 with respect to a specific value is detected in the evaluation device 10, the plate-like object 1 in the direction of the x, y arrows, for example in the Cartesian coordinate system, with respect to the substrate or the storage or support device 13. The arrangement or displacing device) will be controlled via a positioning control line 11, for example, in order to fit the marking 3 to a particular set point in terms of the correct placement and alignment of the object 1.

In the case of misalignment of the object 1, the device 14 for displacing the substrate 13 or the storage or support device in the direction of the X, Y arrows may alternatively or additionally provide for the correctness of the plate-like object 1 for subsequent processing steps. It can be controlled by the evaluation unit 10 to enable placement. Such subsequent processing steps may include, for example, laser drilling using drilling means not shown in detail.

In the embodiment according to FIG. 1, a first having a corresponding second light source 4, for example for the second marking 3 arranged radially opposite in order to achieve an accurate spatial arrangement or alignment of the object 1 to be placed. 2 recording apparatuses 7 may be provided. Alternatively, the recording device 7 can be moved correspondingly into the marking 3 area, in particular light having a wavelength changed or converted to the wavelength originally used for irradiating an object to the marking 3 area or In general, recording of electromagnetic radiation will be done again.

From the detailed illustration according to FIG. 2, it is clear that the marking 3 of the substantially plate-shaped placement object 1 is formed by a complete hole. In addition, the substrate or storage or support device indicated at 13 in FIG. 2 includes a layer 15 of luminescent material at least in the region of the marking 3 of the object 1 to be placed so that the beam path 5 in the light source 4 can be obtained. The light emitted along) is schematically indicated to be converted by the light emitting layer 15 into light of a different wavelength along the beam path 16. After appropriate selection of the optical filter 8, light of this other wavelength 6 passes through the filter and enters the recording device 7. In contrast, light of invariant wavelengths reflected at the surface of the object 1 along the beam paths 16, 17 will be blocked by the optical filter 8 and prevented from entering the recording device 7, thus recording The light entering the device 7 will be the light of the changed wavelength converted by the light from the light source 4 hitting the luminescent material 15 located below the marking 3 along the beam path 5. Therefore, it will be ensured in a simple and reliable manner that the influence of the stray light or the influence of the reflected light does not affect the evaluation of the correct placement or alignment of the object 1 to be placed.

Thus, by simply providing the light emitting layer 15 and thus the light along the beam path 5 with the original wavelength is simply converted to light in the beam path 6 with the changed wavelength, so as to reduce or eliminate misalignment. It is possible to reliably and accurately arrange the object 1 to be arranged.

What is essential in the present case is that the light irradiated from the at least one light source to the object to be disposed corresponding to the beam path 5 is absorbed by the light emitting layer 15 which will emit light, generally electromagnetic radiation of the changed wavelength 6. Said radiation along the outlined beam path 6 is subsequently recorded in the recording device, in particular after passing through the filter 8 and optionally further evaluated.

The fluorescent or luminescent layers shown in FIGS. 1 and 2 may be replaced by, for example, fluorescent or fluorescent colored film or foil, polymer or glass.

FIG. 3 shows a modified embodiment, in which light from the light source 4 along the beam path 5 has a raw or initial wavelength and is irradiated back onto the substantially plate-shaped object 18 in the region of the marking 19. In the embodiment shown in FIG. 3, the object 18 to be disposed is formed by, for example, a multilayer printed circuit board. As is apparent from FIG. 3, the marking 19 is formed by a recess or blind hole provided in the surface of the object 18 to be placed, and the multilayer object 18 to be placed is a beam path 5. Concave so that the light impinging along the light, generally along the beam path 6 and having a changed wavelength, is later converted through the optical filter indicated at 8 into electromagnetic radiation entering the recording device 7. Or a light emitting material layer 20 in the bottom region of the marking 19.

Similar to the embodiment according to FIG. 2, the light reflected from the surface of the object 18 along the beam paths again indicated by 16 and 17 can not pass through the filter 8 or only pass at a very reduced intensity. It is not possible to enter the recording apparatus 7.

Therefore, in the embodiment shown in FIG. 3, it is not necessary to provide the light emitting layer on the substrate 13 or the storage or support device as compared with the configuration according to FIG.

In the embodiment shown in FIG. 4, the object to be placed indicated by 21 has a marking 22 on its upper surface, the marking being similar to the preceding embodiment, the beam path after hitting the light emitting marking 22. The light emitted from the light source 4 along (5) is reconverted to light having a changed wavelength along the beam path 6 so that the converted light is recorded again in the recording device 7 and then optionally subsequently evaluated. It is formed of a luminescent material.

Similar to the embodiment according to FIG. 3, the substrate 13 does not have any light emitting layer of the embodiment according to FIG. 4.

With respect to the substrate 13 or for placement of the plate-shaped object 18 or 221 with the substrate, an apparatus 12 for displacing the plate-shaped object and / or an apparatus 14 for displacing the substrate 13 with the plate-shaped object is provided. It is also provided and can be coupled to the evaluation device arranged to follow the recording device 7 of the embodiment according to FIGS. 3 and 4 similarly to the embodiment according to FIGS. 1 and 2.

2 and 4 indicate that each of the beam paths 5, 6 may be provided with at least one additional light source indicated at 4 ′ in addition to the light source 4, which is indicated or provided for explanation, and further light sources. Can be used, for example, to improve the resolution in the area of the recording apparatus 10.

Instead of the additionally indicated light source 4 ', for example, a plurality of light sources 4' can be arranged almost annularly around the recording device or the camera 7. The advantage of this arrangement over the off-center arrangements represented in FIGS. 1 and 2 is that the influence of shadows, especially with annular configurations, for example in a plurality of light sources 4 'is reduced.

The light source 4 is preferably a light emitting diode, a laser diode, various kinds of lamps, etc. in combination with color filters, for example, to emit light in the visible or ultraviolet or infrared region having a narrow spectral range and thus a well formed color and wavelength. Can be made. The light source 4 of the appropriate wavelength and color will be selected in cooperation with the luminescent material 15, 20 or 22 used to convert the wavelength of the light employed for irradiation of the object 1 to be placed.

In the case of selecting the appropriate electromagnetic radiation, for example ultraviolet light, it is also possible to use the intrinsic fluorescence of the printed circuit board or the object 1 that is generally placed and in particular the material of the polymer, which is carried out according to FIGS. 3 and 4. It is particularly applicable to the example. In a similar manner, this can be applied to the embodiment according to FIGS. 1 and 2 as so-called reversed contrast.

Correspondingly tuned optical filter with filtering function adjusted to the color or the changed wavelength of light emitted by the luminescent material to the marking (3, 19, 22) region with the wavelength changed by the luminescent material 15, 20 or 22 Is used, in particular the light from light sources 4, 4 'will be shielded.

The optical filter 8 having the serially arranged recording device 7 is adapted to distinguish or set, for example, the wavelength changed by the color discrimination or light emitting material 15, 20 or 22 of the recording device 7. It may be replaced by a recording device 7 having a plurality of color channels such as, for example, an RGB camera, which is enabled by the selection of the combination.

Instead of a recording device or camera having several color channels, various kinds of cameras, such as black / white CCD, CMOS and the like, may be employed as the recording device 7.

It is also possible to use a dichroic mirror for the recording device 7 and / or at least one light source region.

For example, when using a plate-like object 1 to be disposed having a plurality of printed circuit boards or printed circuit board elements 2 as indicated in FIG. 1, a plurality of drill holes in the area of the individual printed circuit board elements 2, The treatment of the printed circuit board using a drilling device, in particular a drilling device such as a laser drilling device, to provide passages or microvias is carried out, for example, after completing the placement and alignment of the object 1. Alternatively or additionally, a milling process using at least one milling machine can also be employed.
