"Quo vadis Single Pair Ethernet" - News from the SPE World and a critical Review of Possible Applications in the Industry more
With the IEEE 802.3 SPE transmission standards now available, speeds of 10 Mbit/s over long distances and 10 Gbit/s over short distances are feasible. The presentation highlights the resulting requirements on the interconnection technology, especially the RF requirements up to bandwidths in the GHz range. SPE will conquer many application fields in the future. However, an essential point besides the advantage of SPE with its continuous IP communication is the question of power supply. The main market requirement here, especially for sensor networks, is a cable with an interface. The standard answer to the issue of remote power supply is usually Power over DataLine (PoDL). But is this the most favorable solution or are hybrid interfaces not perhaps the better solution?

The participants learn in the lecture:
  • Status of relevant standardization for SPE at IEEE 802.3, IEC 63171-x and for cabling and interconnect requirements
  • Industrial applications and considerations for the simultaneous transmission of SPE and the power supply
  • Outlook and further development of SPE especially at IEEE 802.3

High Power Levels for Single Pair Ethernet (engl.) more
An SPE connector is introduced that is designed for industrial environments with two pin pairs where one is used for data transmission up to 1 Gbps/600 MHz as defined by IEEE 802.3bp and the other one supports power transmission with currents up to 8 A. This connector is standardized in IEC 63171-6 together with a variant without an extra power pair, which was published on the 20th of January 2020. The hybrid connector with a data and power pin pair features a metal shield separating the pin pairs to avoid the interference of the power signal with the data signal. This all is placed within the form factor of an M8 connector what leads to the challenge of avoiding that higher harmonics from the power transmission, like from switch mode power supplies, do not significantly deteriorate the data transmission.

The participants learn in the lecture:
  • An industrial SPE connector is standardized with separate power contacts that can handle currents up to 8 A
  • The importance of shielding between the power and data contacts to maintain proper data integrity
  • Possible network topologies with a hybrid connector

Floating elements - movement instead of standstill more
The technology of through-hole technology has been used in the electronics industry for decades, which means that components with solder tabs are inserted through a hole in the board and soldered on the back. However, this does not make sensible use of valuable space on the back of the board and the idea of surface mounted solutions, i.e. products placed and soldered on one side only, was developing. Combined with the risk that the connection is only electrically and mechanically connected via the soldering point and therfore any error, especially if the board is only slightly contaminated, could lead to poor connection and thus also to unstable mechanical adhesion of the component. From this WECO developed the Floating Elements Technology, in which components have the property to adapt to the surface, its mechanical deformation with temperature differences and with different melting points of the soldering paste, to a certain extent, and to compensate for these types of defects by the individual mobility of the inner metallic components. This is, in a sense, starfish technology. In the presentation, the pioneering ideas, solutions, advantages and technical properties are presented with examples, investigations and results, and the groundbreaking solution is explained by means of customer solutions.

Application-specific Analysis of the Heating of Power Connectors at High Transient Currents Using Equivalent Thermal Circuit Diagrams more
Connectors as used in high-power architectures of electric vehicles are experiencing high thermal stresses. On the other hand, the high loads in the automotive industry are present for short times only in most cases. Therefore, it is necessary to pay special attention to thermal aspects during design of high-power connectors. Thermal networks provide the opportunity to simulate complex and long current profiles, as occurring in real driving cycles, in an easy manner. Additionally, it is possible to consider specific cooling conditions in the harness/surrounding and convection conditions like ducts or radiators. To harmonize this simulation approach a technical guideline has been generated under leadership of ZVEI (Zentralverband Elektrotechnik- und Elektronikindustrie e.V.).

Optical Dimensional Measurement of Press-fit Zones with Focus Variation more
The rapidly growing electromobility market is just one example of the application of special press-fit technologies for the production of solderless electrical connections. Different types of these press-fit zones have one thing in common: the geometry is one of the crucial factors for a high-quality connection. This fact and additionally the growing demand for this technology lead to more and more complex requirements for the measurement technology. Important parameters, such as the thickness, the diagonal, the radii at the press-fit zone, as well as the geometry at the transitions from the press-fit zone to the press-fit tip must be measured traceably with high accuracy, but also with high measuring speed. The presentation will show how the two technologies Focus Variation and Real3D make it possible to measure high-resolution 360° 3D datasets, which in a further step serve as the basis for evaluating the required parameters. The main focus is on meeting the high accuracy and traceability requirements of the measurement tasks of these components according to the new "IPS 9797-Press fit Standard for Automotive Requirements and other High-Reliability Applications", in which the optical dimensional measurement of the press-fit zone has also been included.

The market is very confusing due to the large number of variants and the large number of private labels. This not only makes the selection of passivation very difficult, but often also prevents several suppliers from being qualified. The creation of transparency is an objective of the project. The precise definition of the testing is also important. There are differences in the test regulations of the manufacturers, but also of the users. Therefore, another goal of the project is to compare the different test methods.

    The participants learn in the lecture:
    • What types of passivation for silver are there?
    • What are the differences?
    • How to test passivation?

    Precious and non Precious Marriages. Is it Possible to Marry Different Contact Surfaces? more
    Noble and non-noble contact surfaces are often offered in identical designs. Manufacturers and industry recommend to match only identical surfaces. The purpose of the contact surfaces is known, the Brownian molecular movement explains the background for the nickel barrier layer. The electrochemical voltage series is the real reason why different contact surfaces should not be plugged together. In connection with the decomposition voltage of water, it explains why contact corrosion can occur. This thesis is supported by practical experience. However, one has to be aware of the effects of pairing uneven contact surfaces, because not only the voltage levels may change, but also the other properties of the connector pair become limited.

    Under power - Conductive plastics cleverly used! more
    Under power - Conductive plastics cleverly used! Across all industries, the requirements for materials with regard to the functional integration of electronic components are growing due to more compact construction methods and new design concepts. The topics of thermal management and EMC shielding play a major role in this context. Their necessary properties can be achieved by the use of plastics. A fundamental understanding of the interrelationships between materials and their effects is the basis for using this group of materials to effectively dissipate heat from components or to achieve the required shielding effectiveness. Within joint projects, investigations have been carried out in this context. In order to derive options for action for one’s own product development, the results are reflected in this presentation. The results of which will be reflected in this presentation with the aim of deriving options for action for one's own product development.

    PVD technology - from corrosion protection to surface conductors more
    A new form of surface modification is presented. A combined process technology is de¬scribed to apply precious metals, e.g. gold environmentally friendly, resource-saving and cost-effective to a large extent geometry-independent (3D) on small parts, e.g. connectors on an industrial scale. PVD technology has been state of the art for many years and is often used to improve tool life. However, the donor material used achieves only about 20 % of its target while the re-maining 80 % land on the walls of the reactor. The coating material is very inexpensive and environmentally neutral, which is why these losses are irrelevant. In the case of precious metals, however, this is the core problem. WBT has developed a method that reverses the benefit/loss ratio. And the remaining 20 % pure gold is almost completely recycled., ecologi-cally problem-free. This process technology consists essentially of the direct connection between high-current plasma polishing and special 3D-PVD technology, which makes working with precious met¬als useful. There are hardly any application restrictions compared to electroplating. The (gold) layers are thinner, but error-free (high vacuum), densely structured and equipped with higher bind¬ing energy. The process energy requirement is about 26 % and the resource consumption is about 35 % lower. It is the qualitative and ecological alternative to electroplating. The disadvantages lie in the high investment in equipment and the demanding handling. On the other hand, the unit costs are even lower in industrial use! Finally, this technology opens up future development possibilities, e.g. to the surface con-ductor, using new, also non-metallic conductive materials, e.g. doped carbon or possibly graphene. Interesting is not only the scalable conductor function of such perspectives, but also the permanent corrosion resistance without additional corrosion protection. In our PP presentation, we would like to present the research results of external institutes on the topics of abrasion resistance, corrosion behaviour and contact quality.
    Speaker: Wolfgang B. Thörner | WBT-Industrie

    The business economist (FH) gained technical experience in the automotive industry before founding the WBT industry in Essen in 1985. The purpose of the company was the development and production of high-quality electromechanical connectors. In the course of time, what began as a purely mechanical engineering company has become more and more a company with nanotechnical know-how within the framework of precision engineering. Today, in addition to plastic manufacturing, WBT also runs complex surface (3D) PVD-Plasma modification, which can process metals incl. precious metal, and potentially also semiconductors, on a serial scale. The performance range spans from corrosion protection to surface function conductors. ...and the WBT high-performance connectors are available after-again.

    Latest Developments in Multi-slide Die Casting more
    The trend in connector industry targets for years in reducing space, reducing weight, performance compression, shielding and developing modular systems. In this respect, "miniaturization" is no longer limited to designing devices and components ever smaller, but increasingly requires more precise and complex components and surfaces. This leads to new challenges for die-cast parts: - increasingly thin walls - tighter tolerances - surfaces with technically, visually and haptically higher quality While the optimization potential of conventional tool and casting machine technologies has been largely exhausted, interesting further developments in multi-slide die casting have been advanced and brought into mass production readiness. In the presentation, the multi-slide die casting technology will be presented as well as its possible application areas (including advantages and disadvantages) compared to conventional die casting technology. The main part of the presentation shows the latest developments in multi-slide technology: - Shortening the casting runners (distance of the melting pot to the die cavities) - Servo drives for better process control (parameterization of the complete injection process) - Development of the hot chamber multi-slide technology for aluminum The consequential new design options for components made of zinc, aluminum and magnesium are then presented by using examples. The presentation targets at die casting experts as well as expressly at non-experts. The non-expert (e.g. project manager, strategic buyer) will be introduced to the function of multi-slide die casting technology and its typical areas of application, and will learn which components and geometries can be advantageously manufactured with this technology. The experts (e.g. device developer and component designers) will be introduced to the latest developments in multi-slide die casting technology and the resulting expanded design options with regard to geometries and tolerances.

    State of the Art and Trends in the Additive Manufacturing of Connectors more
    Additive manufacturing offers enormous potential based on a significant increase in design freedom. In order to be able to fully address these big advantages, it is necessary to qualify new materials for additive manufacturing.  PROTIQ has succeeded in developing a process with which copper can be processed using additive manufacturing. With an innovative copper alloy, PROTIQ was the first service provider, which was able to produce inductors of the highest quality. Today PROTIQ can also process 100% pure copper in 3D printing.  The material zinc opens another interesting field of application. Components made of the zinc alloy Zamak 5 for zinc die casting are widely used. PROTIQ has succeeded in developing a process for additive processing of the series material Zamak 5. Based on that, prototypes as well as small series are now able to be produced at a low component price.
