SolidWorks in automotive electronics design

   In order to shorten time to market and the competition ahead of the competition, electronic product designers need to address the changing needs of the electronics industry.

    The continuous development of electronics and semiconductor technology, resulting in electronics, mechatronics (electro-mechanical, electronics and software co) and design tools to rapidly changing system components.

    Need to make products with more features, but the product size is not greater than previous products and competing products, or even require less. Competition to promote the development of the electronics industry, smaller but more perfect devices. This requires tools for product design to "a more economical use of" physical space.

   More features usually means a higher complexity of electronic products and components required to dissipate. The sake of market demand, even in the new models to add new features, products can not change the size of shell,ratchet tie dowm but that it needs to maintain the original size of the same, or even smaller. In addition, greater levels of packing density for greater level of detail parts to optimize the appropriate fluid analysis.

   Some of the emerging global environmental standards, such as RollS (Restriction of Hazardous Substances), the directive restricts the use of lead and other substances harmful to the environment, and requires from 1 July 2006 onwards, sold in the EU market and deal with all products must meet the requirements.

   With the continuous micro-controller system miniaturization, more traditional hardware components (such as switches and displays) are being replaced by software functions. For example, a few years ago required a total of 12 buttons to operate a product, now with two buttons plus an LCD display can do it.

   Automotive electronics industry challenges.

   As technological advances in the electronics industry, ECAD systems are becoming increasingly complex. They become more and more expert system requires the operator to use them to carry out a very professional design.

   Due to mechanical engineers and electronics designers to use a different system, so the lack of interoperability between these systems, resulting in duplication of work and takes too much time to convert data between them.

   As in electronic engineering and mechanical engineering lack of interoperability between CAD systems, thus creating inefficient products, this is because the electronic and mechanical design will be added in the product. Repeated elements "to make up for the lack of accurate information between the two systems for this shortfall.

   In order to sell products under the global economic environment, international standards are being expanded, not only include DIN.ANSI and ISO. Also RoHS (Restriction of Hazardous Substances). In order to provide products to the market in time, early in the process must know the electronic components and materials necessary to comply with this standard, because it involves costs and procurement issues.

   Many electronic components have not yet formed a unified industry standard. Now, more and more established 3D model, but together with the geometric data, there is no standard to how to pass those embedded with the components of non-geometric properties (such as materials, compliance with standards, source, etc.).

   Automotive design process.

   Product development cycles are becoming shorter, so that all stages of the design cycle, your challenges and can deliver results are different. You need to be completed within a shorter time, more work. Let us look at the basic electronic product development process.

   Determine the parts specifications - first request a new product concept. This can be provided to improve the current product, it can be put forward a new original concept (breakthrough). Can determine the start of the project components in the specification, but more often is accompanied by the generation of concept carried out. Component specification is defined to determine the initial product concept is effectively trying to aim the concept into practical products.

   The package design of a next stage of product design by many to be the core of the conceptual design process. This stage of product design process can be extended to include its own process, but in terms of electronic product design, from industrial designers and mechanical engineers to determine the appropriate concept (the concept outlined in the product meet the specified requirements, but also for the requirements of square inch area of ??the data originally provided by the electrical engineer), then get on board through their size and shape of the tips.

   If the package design of a PCB design is the core process of product design, then the electronic design PCB design is the core of the process. The preliminary PCB layout (with the main components, connectors, and switch / interface with the location) after the transfer of electrical engineering, electronics engineer will be responsible for the detailed design of PCB and interconnect. Almost inevitably, PCB designers will have to specify the components of mechanical engineers, the minor position (and sometimes major) changes. Also, avoid designated areas, and between electronic engineers and mechanical engineers agreed to this in order to avoid invasion, tracking areas. After the initial design through the IDF will return to the mechanical engineer.

   Production prototype - in some stage of product design process, must be in the form of physical prototype "implementation" design. Prototype a variety of forms, from the mechanical test case to the circuit board, to a one-time, full-featured "near production status," the working model and so on. This design process is an important milestone, all the professions into a unified solution. Mechanical shell and prototype PCB and interface are important for different purposes, including fit and trim, thermal analysis, functional analysis (stress, drop test, etc.) and for assembly manufacturing. The group also focuses on the prototype for proof of concept.

   Delivery of production - Finally, the production of customer documentation and manuals. This is another time-consuming and cumbersome process. Late in the development cycle if design changes occur, you must also update these manuals, spare parts and maintenance process in order to maintain bill of materials information.

   Of course, this is not a linear process. Driven by many factors, always like to design iterations many times, and these factors include: changes in customer demand; internal engineering design changes: the manufacturing sector and suppliers and request changes.
