Definitions
- the invention relates to a drilling device of the type mentioned in the preamble of claim 1 for drilling contacting bores for connecting contact surfaces of at least one first layer of a multilayer printed circuit board with contacting surfaces of at least one second layer of the multilayer printed circuit board.
- printed circuit boards In the course of increasing miniaturization of electronic assemblies, it is necessary to provide an ever larger number of components or printed conductors on a given surface, for example of a printed circuit board. For this reason, it is known to design printed circuit boards as so-called multi-layer or multi-layer printed circuit boards, in which the printed circuit board consists of a plurality of individual printed circuit boards arranged one above the other in layers, so that components or printed conductors on the front and back sides The individual printed circuit boards and thus, due to the layered structure, can also be arranged between the individual printed circuit boards which follow each other in the layer. In this way it is possible in particular to realize printed circuit boards with a particularly high number of printed conductors, which can not be accommodated on a single printed circuit board. NEN.
- the individual printed circuit boards whose layering forms a multilayer printed circuit board, are firmly connected to one another, for example by pressing or gluing.
- the layers on Kunststofftechniksflachen which are also referred to as pads.
- the contacting surfaces can be arranged, for example, perpendicular to the printed circuit board plane of the multilayer printed circuit board, one above the other on the layers.
- the contacting bores must in this case be designed so that an electrically conductive contact between the contacting surfaces is made possible in the desired manner. This is readily possible if the contacting surfaces are arranged exactly above one another perpendicular to the printed circuit board plane of the multilayer printed circuit board. It should be noted, however, that when connecting the layers of the multi-layer printed circuit board, for example by pressing, a high surface pressure is used in conjunction with high temperatures. Due to this, when the layers are bonded, a positional offset between the same ben occur. Such a position offset can be based on the fact that the individual layers shrink or stretch and / or shift relative to one another parallel to the printed circuit board plane and / or rotate relative to one another about an axis running perpendicular to the printed circuit board plane.
- a drilling device of the type in question for drilling contacting bores for connecting contact surfaces of at least one first layer of a multilayer printed circuit board with contacting surfaces of at least one second layer of the multilayer printed circuit board is known.
- the known drilling device has drilling means for drilling the contacting bores and control means for generating control signals for controlling the drilling means corresponding to the contact bores to be bored in each case.
- the circuit board has receiving holes, with which they on corresponding to a carrier, for example a Drill table, the drilling device providedchir ⁇ pins can be plugged. Due to the position of the receiving holes, the position of the printed circuit board is thus defined relative to the carrier.
- the printed circuit board is introduced into an X-ray measuring device, so that any positional offset between the printed circuits Layers of the circuit board can be determined, as known for example from DE 33 42 564 C2. If a position offset is determined, then the position of the receiving holes can be selected such that the positional offset is completely or partially compensated during the subsequent drilling of the contacting holes, provided the positional offset is within certain limits.
- the printed circuit board After determining the positional offset and drilling the receiving holes in the printed circuit board, the printed circuit board is removed from the X-ray measuring device and placed in the drilling device, where it is attached to the receiving pins of the carrier. Following this, the drilling means of the drilling device drill the desired contacting bores.
- the invention is based on the object
- This object is achieved with regard to the Bohrvorrich ⁇ tion by the teaching specified in claim 1 and Hin ⁇ the method by the ange ⁇ given in claim 14 teaching.
- the determination of a positional offset between the first layer and the second layer of the printed circuit board and the drilling of the contacting holes are carried out in one and the same device.
- the printed circuit board can remain fixed both during the determination of the positional offset and during the drilling of the contacting bores on a carrier, for example a drilling table of the drilling device. This reliably prevents inaccuracies in the drilling of the contact holes due to mechanical mating tolerances with respect to the receiving holes and the receiving pins. Since, according to the invention, receiving holes in the printed circuit board are fundamentally not required and the printed circuit board can thus be formed without receiving holes, the accuracy of drilling the contacting bores does not affect the fitting tolerances with respect to the receiving holes.
- the printed circuit board Since both the determination of the positional offset and the boring of the contacting bores in the same device, namely the boring device, are carried out, the printed circuit board is given the same ambient conditions both during the determination of the positional offset and during the boring of the contacting bores. especially with regard to temperature. In this way it is prevented that the geometry of the printed circuit board in particular due to temperature differences between the determination of a positional offset and the drilling of Mais michsbohrun- changed. Such a change in the geometry can occur in conventional devices in particular when the printed circuit board is removed from the X-ray measuring device after the determination of the position offset and introduced into the drilling device, and lead to inaccuracies when drilling the Kunststoffmaschinesboh- ments.
- the drilling means have at least one laser for forming the contacting holes.
- the precision when drilling the contacting bores is even further increased.
- the speed at which the contacting bores are drilled is substantially increased over mechanical drills.
- a further advantage of using a laser for drilling the contacting bores is that, if appropriate, adaptation of the diameter of the contacting bores can be achieved by suitable beam shaping and / or focusing of the laser beam. A time-consuming change of the drill required for mechanical drills is thus eliminated according to the invention.
- the Vorrich ⁇ inventive device is particularly simple and inexpensive to produce, as compared to the prior art, the design complexity is significantly reduced. While in the prior art due to the fact that both a se ⁇ parate device for determining a positional offset, for example in the form of an X-ray measuring device, as well as a separate drilling device are required, essential and expensive components, for example in the form of the control, a positioning table for positioning the printed circuit board and a housing, must be present twice, these components in the drilling device according to the invention, in which the means for determining a positional offset are integrated into the Bohr ⁇ device, only once required.
- the drilling device according to the invention is thus not only substantially simpler and less expensive to produce than the prior art, but also has a considerably reduced space requirement.
- an integration of the means for determining a positional offset in the drilling device is understood according to the invention that the drilling means and the means for determining a positional offset are in spatial and / or functional contexts such that, in particular, the determination of the positional offset and the boring of the contacting bores can take place without changing the position of the printed circuit board relative to a carrier which holds the printed circuit board.
- an integration of the means for determining a positional offset into the drilling device means that the drilling means and the means for determining the positional offset are arranged in immediate spatial proximity to one another.
- the teaching of the invention provides a support for the circuit board, wherein the carrier, the circuit board during drilling of Kunststoffssentechniksbohrungen substantially Positionsver Sungsok based on the position of the circuit board holds in the determination of the position offset.
- the circuit board occupies substantially the same position relative to the carrier both in determining the positional offset and in drilling the contacting bores. In this way, misalignments of the contacting bores, which could result from a change in position of the printed circuit board relative to the carrier, are reliably avoided.
- the printed circuit board can be fixed to the carrier during the determination of the positional offset and during the drilling of the contacting bores by means of fixing means.
- the fixing of the printed circuit board to the carrier can take place in any suitable manner, for example by mechanical clamping or by firmly squeezing the printed circuit board on the carrier via a suction device.
- a carrier is understood to mean that component which directly holds the printed circuit board, irrespective of the mechanical structure of the carrier.
- the carrier may be, for example, frame-like or as a table on which the circuit board rests flat, be formed.
- the carrier is designed such that the printed circuit board can only be released for removal from the device after drilling of the contacting bores.
- the control means with fixing means which fix the circuit board to the carrier, are in Steuer ⁇ compound, and control the fixing means after drilling the Kunststofftechniksbohrungen so that the circuit board is released for removal.
- Another embodiment of the invention Teaching provides positioning means for positioning the circuit board relative to the drilling means and / or the means for determining the positional offset.
- the printed circuit board can be brought into a desired position relative to the drilling means or the means for determining the position offset, so that the drilling means and the means for determining the positional offset are stationary can be arranged on a base body of the device.
- the positioning means can spielvati be formed by a precision XY table, which has or forms the support for the circuit board.
- the printed circuit board can be positioned by the positioning means at least in a plane parallel to the printed circuit board plane relative to the drilling means and / or the means for determining the positional offset. If desired in accordance with the respective requirements, however, the printed circuit board may also be positionable in a direction perpendicular to the printed circuit board plane, relative to the drilling means and / or the means for determining the positional offset.
- the determination of the layer offset can be carried out by means of any suitable method.
- An advantageous development of the teaching according to the invention provides that the means for determining the positional offset determine the positional offset by means of an imaging method.
- the means for determining the position offset at least one X-ray Measuring device for measuring the position offset aufwei ⁇ sen.
- Such X-ray measuring devices allow a measurement of the circuit board and thus a measurement of the position offset with high accuracy.
- the X-ray measuring device has at least one microfocus X-ray tube. In this embodiment, the measurement of the Lagen ⁇ offset can be done with very high accuracy.
- the X-ray measuring device can be designed in particular as an X-ray microscope.
- control means are programmed such that the control of the drilling means only takes place when the determined positional offset of the layers relative to each other exceeds a predetermined value.
- the contacting holes are drilled only when it is ascertained on the basis of the determined positional offset that the desired electrically conductive connection between the layers of the printed circuit board can be achieved by means of the contacting bores. If, on the other hand, it is determined that the positional offset falls below a predetermined value, due to which a desired electrically conductive contacting of the layers by means of the contacting bores is not possible, the printed circuit board can be discarded. In this way, a time-consuming and cost-consuming further processing of such printed circuit boards is avoided, which can not be functional due to a layer off-set lying outside predetermined tolerances and must accordingly be discarded.
- the means for determining a positional offset can Determine gene offset based on the Kunststofftechniksflachen the Schich ⁇ th the circuit board and / or based on arranged in or on the layers of the circuit board Markierun ⁇ gene.
- Printed circuit board of a carrier when drilling the Kontak- t istsbohronne relative to the carrier held substantially positional change in relation to the position of the circuit board in the determination of the positional offset.
- the contacting bores can be drilled with high accuracy, without this accuracy being caused by position changes of the printed circuit board relative to the carrier, which occur in the prior art in that the printed circuit board is supported by a carrier of a device for determining ⁇ ment a positional offset is removed and placed on a Trä ⁇ ger a separate drilling device is impaired.
- Essential in this context is the freedom of changes in position of the printed circuit board relative to the carrier in a plane parallel to the printed circuit board plane.
