Definitions
- the invention relates to a method for producing an electronic circuit in a manufacturing plant.
- a circuit carrier is provided.
- This circuit carrier is subjected to at least one process step for producing the electronic circuit.
- Typical process steps that are used in electronics manufacturing the placement of a circuit substrate with components, the application of joining media, eg. B. the printing of the circuit substrate with a solder paste, the soldering, which selectively, for example, with a
- Lötwellenvoriques can take place or can be done in a reflow soldering oven, or the application of flux to electrical contacts.
- a circuit carrier for example, printed circuit boards can be used.
- other components are to be understood that fulfill the function that an electronic circuit is constructed on this. For example, there is the possibility
- the invention relates to an assembly with an electronic circuit having a circuit carrier up, are connected to the components of the electronic circuit.
- a circuit can be considered as a product to be produced of the above-mentioned method.
- the invention also relates to a production plant for producing an electronic circuit on a circuit carrier, in which at least one process step for production can be carried out.
- This production line is therefore also suitable for carrying out the above-mentioned method.
- Assemblies with electronic circuits, processes for their production and production plants, with which these processes are carried out, are known from the prior art
- test plates can be passed through the manufacturing facilities, which are provided with sensors that allow certain statements about the ongoing manufacturing process. These sensor plates detect data and readings in addition to the built-in sensors in the manufacturing facility, allowing for a review of the manufacturing process as such and the reliable operation of the sensors installed in the manufacturing facility. In this way, reference data for a manufacturing process can be obtained, which are taken into account in subsequent manufacturing steps.
- the object of the invention is to provide a method for producing electronic circuits, with which a comparatively close-meshed quality control of the manufacturing process is possible. Moreover, it is an object of the invention to provide an assembly with an electronic circuit, with which the quality management is simplified during the manufacturing process. Finally, it is an object of the invention to specify a production plant with which an improved quality management of a manufacturing process for the electronics assembly is made possible.
- the circuit carrier is in front of the
- a measuring module in the context of the invention is an assembly to understand with which a measurement can be performed.
- the Measuring module has for the purpose of measurement at least one sensor. The measurement is carried out independently by the measuring module.
- the electronic circuit on the circuit carrier is not yet finished during the process step and its functions therefore can not yet be carried out, or at least not yet completely, according to the invention the measuring module is already able to assume the task of carrying out a measurement.
- the measuring module carries out this measurement during the execution of the at least one process step, so that during the process step additional measurement data are generated which are not determined by sensors permanently installed in the production plant.
- the measuring module After completion of the at least one process step (and possibly even further process steps), the measuring module is disconnected from the circuit carrier.
- the releasable connection is provided according to the invention.
- the advantage of this measure lies in the fact that the measuring module, after being released from the circuit carrier, is available for further circuit carriers to be produced, to which the measuring module can be detachably attached again.
- the measuring technique used in the measuring module can therefore be of comparatively high quality, since it does not remain on the circuit carrier and thus does not directly influence the unit costs of the circuit carrier. Rather, the acquisition of the measuring module or several measuring modules are investments that only indirectly affect the entire series of circuit carriers.
- measurement data can be generated with high-quality measuring modules that describe the states in the immediate vicinity of the circuit carrier. With these, the at least one process step can be controlled directly. Quality problems during the process step can be reacted immediately.
- the measuring module accesses an electronic component which is part of the electronic circuit on the circuit carrier during the at least one process step.
- This must therefore be an electronic component whose function is already ensured during the relevant process step, at least with regard to the intended scope of access by the measuring module.
- the access can be done, for example, for the purpose of checking the function of this component, in which case a measured value can be generated which describes the proper functioning of the component.
- Another possibility is to use the component for a function that ensures the work of the measuring module.
- the component could be used to store data generated by the measurement module. These data are then advantageously also available for later process steps if the measuring module is already separated from the circuit carrier.
- the component could also be an antenna.
- a component in the context of this invention is understood to be a functional unit which makes available the access of the measuring module for the use of the function requested by the measuring module.
- This functional unit can also consist of several components.
- the measuring module after it has been disconnected from the circuit carrier, is replaced by another electronic module.
- This other electronic module for example, also take over measurement functions that are needed after completion of the production. For example, measured values could be used for the later transport or operation of the circuit carrier to be helpful.
- the measured values to be generated in this connection are, however, to be produced using less expensive sensors which, for example, do not have to withstand the ambient temperatures of said process step (for example during reflow soldering).
- the other electronic module can be advantageously carried out cheaper because of this.
- a particular embodiment of the invention is obtained when the measurement module generates measurement data during the measurement and forwards it to the production facility via an interface. This advantageously makes it possible to evaluate the determined measurement data even during the process step and thus also to be available for controlling the process step.
- a control unit is used, which in the context of the invention is understood as part of the production system.
- this control system can also process further data, which are determined, for example, by sensors permanently installed in the production plant.
- the interface is the storage of the measured data in the measuring module or, as already mentioned, on the circuit carrier.
- the measured data are available for an evaluation following the process step. This also makes it possible to carry out a quality control in production processes that are already running with optimized process parameters. For example, aging-related quality fluctuations in the production plant can be demonstrated in this way.
- the measuring module generates measurement data during the measurement, processes it and, depending on the result of the processing, forwards the data describing the measurement result to the production plant via an interface.
- the measurement module does not deliver the measurement data itself to the production plant, so that they are only there for data processing Generation of control commands, but the measuring module itself already has a means for data processing (intelligent measuring module). For example, only leaving certain tolerance ranges can be sent from the measuring module to the manufacturing facility, such. For example, a diagnostic feature is detected for "offset in XY plane.” The control commands are then generated in response by the controller, such as "correct offset in XY plane".
- the measure is that the measuring module, depending on the measured data, even forwards control commands for influencing the at least one process step via the interface to the production plant.
- the measuring module can be hierarchically embedded in a control environment for the production plant, so that the control commands are implemented directly by the production plant.
- the control command is first passed via the interface to the control device of the manufacturing plant, so that the sum of the control commands converges in the control device.
- measurement data which originate from a sensor outside the measuring module are also processed in the measuring module.
- Other sensors may be either other measuring modules which are mounted on the circuit carrier located in the process step or of other circuit carriers also located in the process step.
- sensors that are permanently installed in the production plant can also be used if they can pass on the measured data to the measuring module via the interface.
- the interface of the measuring module according to the invention must ensure the transmission of data.
- This can be wireless or wired.
- a wireless design advantageously simplifies the handling of the measuring module, for example when mounted on the circuit carrier. The handling of the circuit module equipped with the measuring module carrier is thereby simplified.
- Interface advantageously has an increased reliability in the transmission of the measured data.
- the coupling of the measuring module with other sensors can be used advantageously for different purposes.
- the comparison of measured data makes it possible to calibrate the sensors (outside and inside the measuring module).
- sensors with the highest measuring accuracy can be given priority.
- Another possibility is to prioritize the measurement data generated by the measurement module at the location of the circuit carrier, while stationary sensors of the production device, which can generate measurement errors due to the distance to the circuit carrier, are calibrated with the aid of the measurement data generated by the measurement module.
- By recording a data history it is also possible that, for example, drifting of the measured values caused by aging of the sensors in the production plant can be corrected.
- the measuring module can be attached to the circuit carrier by gluing, burping, plugging or with magnetic forces. All these compounds can be advantageously easily solved again and thus allow multiple use of the measuring module.
- the at least one process step to be examined can consist of soldering of the circuit carrier, loading of the circuit carrier, wetting of the circuit carrier with a flux or the formation of solder connections on the circuit carrier (by wave soldering or reflow soldering).
- These process steps are usually required for the manufacture of electronic circuits.
- the measuring module can only pass through one of the mentioned process steps or, as a consequence, several of these process steps, it also being possible for several sensors to be accommodated in the measuring module, which are adapted to the requirements in different process steps.
- the above-mentioned object is achieved by the assembly according to the invention, wherein the circuit carrier, which carries the assembly, moreover, releasably connected to a measuring module.
- the measuring module according to the invention is functional in terms of its power supply and its measured value generation independently of the electronic circuit. With this module and the measurement module detachably mounted thereon, the above-mentioned method can be carried out according to the invention. The advantages mentioned in connection with the above-mentioned methods can be achieved thereby.
- the measuring module should be reusable, ie after carrying out the process step in which the measured values which are to be generated can be detachably connected to another circuit carrier which has not yet passed through said process step.
- the measuring module has a self-sufficient energy source. This has the advantage that the measurement module does not have to be contacted with an external energy supply during the measurements during the process step. The self-sufficient energy source ensures the function of the measuring module during the process step.
- an energy storage such as an electric battery can be used.
- This can be equipped with a charger, which enables a wireless charging of the measuring module.
- Another possibility is to provide an energy converter which converts, for example, thermal energy of the process step (eg during reflow soldering) into electrical energy for the measuring module.
- the energy converter can also be used as a charger for an energy store in the measurement module, so that even in times when the energy converter does not produce enough energy, the energy required for operation can be made available in the measurement module via the energy store.
- an electronic memory module and / or an electronic transmission module and / or an electronic memory module on the circuit carrier can be advantageously provided that an electronic memory module and / or an electronic transmission module and / or an electronic memory module on the circuit carrier
- Receiving module (this includes an electronic transmitting and receiving module with) is provided, which / which is releasably electrically contacted with the measurement module / are. These are thus components that are to fulfill a specific function on the circuit carrier after its completion. These can, if this function can already be called up during the production step, be used by the measuring module when the measuring module is electrically contacted with these. Of course, this electrical contact must be made detachable, since the measuring module to be removed after completion of the process module of the circuit board.
- the cited individual modules can be designed to be separated from one another on the circuit carrier in each case as individual components or assemblies. Alternatively, however, these functions can also be integrated into an assembly or a component, which as a whole is electrically contacted with the measurement module.
- a transmission module ensures unidirectional communication with the production plant. This is a prerequisite for the measurement module to be able to pass measured data, measurement results or control commands to the production facility. If a transmitting and receiving module or one transmitting module and one receiving module are provided, the measuring module can also receive data from the production plant. For example, different measuring functions of the measuring module can be called up by the production plant if the occasion for a specific measurement for Securing the running process step exists. As a result, the transmitted data rate can advantageously be reduced since the measuring module only has to carry out measurements when required.
- Measured values can be stored in a memory module. These measured values can be evaluated either by the measuring module itself or by the production device. For example, a measurement data history can be used to determine whether there are drifting process parameters that must be corrected in case of doubt. It is also possible to use the measurement data for calibrating the sensors in the measurement module or for external sensors from the production plant (as already described).
- the further modules memory module and / or transmitter module and / or receiver module
- the further modules can of course also be integrated in the measuring module. These are then removed together with the sensors after the process step has been removed from the circuit carrier.
- all these components of the measuring module are housed in a common housing.
- the object is also achieved by the production plant specified at the beginning, the production facility having a measuring module with at least one sensor which is movable in the production plant.
- This mobility ensures that the measuring module can be releasably fixed on the circuit carriers to be produced and can remain firmly connected to the circuit carrier during a process step of the manufacturing plant to be performed. Subsequently, the releasable fixation allows removal of the measuring module and mounting on another circuit carrier to be produced.
- the production facility according to the invention has a data interface via which a data connection to the measurement module can be established. This makes it possible while the implementation of said process step to establish a data connection with the measuring module, so that the manufacturing plant can evaluate this data for the purpose of process control.
- the associated advantages have already been described in connection with the method according to the invention indicated above.
- a sensor mounted in the production facility is present, which can communicate with the measurement module via the data interface.
- the measurement module can communicate with the measurement module via the data interface.

- quality control can be carried out by means of short control loops in the production process. The result is a reduction of the scrap of products to be manufactured (circuit boards), as can be intervened in the running manufacturing process at a relatively early stage.
- Detailed process details during the entire process chain for the manufacture of the circuit carrier can be determined and stored specifically for specific products or workpieces.
- Another advantage is a reduction in the maintenance of the system, for example, by omitting a program creation on site.
- the maintenance intervals and manually tracked process corrections are also reduced, as errors can be detected more quickly and the necessary measures can be initiated based on this.
