If We evaluate the past few years, when most electronics companies faced the commercial crisis and the slow recovery. To keep ahead of competition, demand development increased significantly. The project ‘Technical Leadership Award “Mentor was an obvious evident because of this. Every year, most companies around the globe to present their innovative design are invited, and paid a group of independent experts from industry the initial assessment. Finalist design from 2012 is much more complex, methods of design and style and the tools used in the process is also much more advanced than before. in this article the use of the technology described in expected to promote the role future will not be a luxury, but an essential development.
a survey by Aberdeen Group, many leading electronics companies confirmed that it will meet with the design of six practices that will meet the business objectives actively. with the slow recovery of the economic situation, these basic practices of PCB technology can be an essential part of every company increased in 2012.
the electronics companies are trying to recover commercial crisis, the pressure to provide comprehensive support from design to manufacturing process also may be increasing greatly. electronics companies worldwide have differentiated to take to the market faster with a much lower cost, along with the trend will continue due to economic weakness products. Even in China PCB market, to further improve productivity also have to apply modern technology to design systems and manufacturing support tools.
The following is additional information on six key strategies that can make smarter work, we assume that in these six key strategies can be key to future development.
I. process of collaborative product development
in general, collaboration refers to the ability to change operation serial to parallel operation, and now has two modes. First model was allowed several programmers work simultaneously on the same design flow. No back on the market, however, is the difference in efficacy compared before. Designers are always able to operate the database and PCB design division, each designer is doing work in the design process. But the database must recombine, though rapid ejaculation time consuming and error easily occurs, it could shorten the cycle look towards the end!
Currently, we now have the ability to allow multiple designers to work simultaneously on the same database, without splitting the database. Usually used for various PCB design processes, for example, entries schemes, which limit inputs, management and physical distribution. In addition, design leaves begin to see the results in real time of others. It is not only significantly reduces the cycle time of the structure, and also improve productivity with superior product designers. reports show some users technology saves 30 to 70% of the time structure. Companies need to get similar improvements to help keep competitive.
The second model is the ability to run several different processes, and is a parallel pattern which may be different sequences form. Schemes, restrictions and distribution analysis can be parallelized, thereby improving productivity and shorten best designer design cycles. However, this mode requires the management of complex design data containing version management, synchronization, calibration, permits, which is explained later in this post.
II. virtual prototyping
Usually companies to build and test several prototypes to validate many. To design a PCB, building physical prototypes, testing laboratory that changes are needed, then re-design, and after repeating the appropriate processes. However, there are many problems in this way. First, it is extremely expensive and time-consuming. You will miss the best time in the event that the indicated time can be quite urgent. Secondly, we simply can not discover each of the potential problems. For example, if you expect how the product can be used for several years in a strong vibration along with other harsh environments, but ‘vibration and hot treatment’ laboratory maybe can not run a sufficient length to find the long cyclical problems. In addition, signal integrity contains the same problem. Extremely critical condition may not get inside the laboratory.
Solutions are simulated in software from now on, including virtual prototyping. This can be operated within PCB design process, and applied to a growing number of areas, for example IC package, PCB and simulation of the entire thermal management system ,? PCB manufacturing? And practice mounting 3D mechanical interface, etc. . In all the flow, you can ensure that the design and style continue without backup and correction. What’s more, the application can detect extremely critical condition, and simulate the problems that may occur in the laboratory for a lot of weeks and months, only a few hours. Although designers prefer to get real products and virtual prototyping coextensive made could be delayed, however, it can help limit the cycle and lowering the price, too, the productivity of designers, high quality and reliability with products to be improved.
III. Support process from design to manufacturing costs
and right time for the market is the factor of many industries. Even the aerospace and automotive industries military additionally limit any long development time and high cost faced as it needs to be improved. In addition, PCB designer has to be aware that their responsibilities are still continuous data are within the manufacturing process. What’s more, from the perspective of EDA vendor support could be more important compared with the end of the design phase and style, standing with manufacturers to optimize their production lines and achieve the lowest cost of delivery they tend to be important that enable designers to simply fulfill their responsibilities can manufacture products.
Flow is evolving the many time, help manufacturers define support policies and practice from the beginning, a confidence in the product and reliability impact. These rules DFM will be used to create process. DFM software can identify problems in the design environment and style and could be corrected because the designers. Coincidentally, most manufacturers make use of the same rules and design software to determine the received data. This ensures that once the design and style put into the manufacturing process, can still perform without rework design.
Once the design and style get through intelligent interfaces including ODB ++, when they end up in the manufacturing process, manufacturers can use the software program for modeling and optimizing series. When the line of development is executed, the software continues to monitor on-time delivery of parts, downtime of the machine and product traceability and also other problems. Even in the case of quality defects, what is more, it can make sure the track and highlight the unit or process with low failure rate.
IV. Managing complexity
For differentiated products that could beat competitors, companies will have to spend advantage in the latest technology and innovative, more features, probably will be compressed into a smaller space and meet timing positive market at the same time, they will be more important in the future. integrated circuit technology for high-density areas, is likely to be continued high speed improved. manufacturing techniques of printed circuit boards, such as HDI / tiny holes, the density may be higher, but the design and style is also more difficult. Faced during use of increasing complexity, which is precisely maintain and improve designers’ productivity? The answer is to increase the functionality of the design tools.
For example, recently, a standard design may include some high-speed networks that can meet the length and standards. These networks can be easily handled by designers. Now, reading great designs transmit more than 50% in the high-speed network, and also some about 90%. Another example is the greater of BGA pin count and density. This will become a challenge when fan-out of PCB. This situation raises a problematic issue, productivity will decrease and the time that appears will expand significantly if no advanced design tools.
V. Interdisciplinary Cooperation
Product development and delivery requests interdisciplinary cooperation. In the field of electronics. And now we have experts in analog integrated circuits, packaging, FPGA, RF, and aspects of digitization. Moreover, from the field of mechanics, we now shell design engineers and CAE analysis. What’s more, we now hiring, supply chain and manufacturing personnel and embedded software development. All these need the effective cooperation of research and development. This paper and e-mail cooperated before, now largely electronically, but in reality is still a problem for members to save huge amounts of data.
Actually, most of the interaction is a form of consultation. For example, if the mechanical engineer found an item in the PCB would shell interference physical product, believes can change the location on the component. a stepwise manner (not until replacement) offer PCB designers will be required. Then PCB designers should check and ensure the proposed sequence. Gradual changes in the proposed performance standard EDMD by Mentor Graphics, PTC and users, but they got the approval of ProSTEP. This proposal is likely to be shown as an image PCB designers, the second will, reject or make a better suggestion depends on the actual situation on the PCB related. This continues before reaching an agreement, in addition to the database mechanical and electrical will be updated. This is a sign of great importance and fully electronic cooperation in tangible real operations.
VI. management of intellectual property
Top-One electronics companies determine that managing their work processes and databases is the answer for future success. For members of the team structure, whether they are in the scattered site local or world wide, is needed to produce a valid authorization, and manage the most important asset strictly business. database administrator places the components qualified for infrastructure approved management information could be assessed by designers. PCB predesigned could be added to the database and is used in the future
With the progress of board design, layout, PCB design constraints, and manufactured data. It is very complicated for data management, and yes it is necessary to create special systems infrastructure for IP management. The date of issue will face different problems associated synchronization and version management. Companies can hire agencies to create product parts, and easily share part of the IP, which exclude the complexity by using standard PLM system. Means, mature development of the site, the latest design data need to be uploaded to any enterprise PLM, ERP systems management lifecycle.
