pcb electronic products of the body, the final product performance, life and reliability of the electrical system depends on its composition. If properly designed, the circuit has a high-quality product will have a lower field failure rate and field return rates. Therefore, the production costs will be lower, higher profits. In order to produce high quality PCB board on time, without increasing design time without creating costly rework, it must be early detection and circuit design integrity issues in the design process.
For the product to market quickly and reliably, the use of design automation tools to achieve the design process it is very necessary, but how to ensure the success of the design it? To maximize design efficiency and product quality, which should be concerned about the details? Obviously intuitive design tools and should be strong enough to overcome the complex design challenges, but there are issues which deserve attention? This article lists the four steps to be taken to ensure the success of the PCB design.
Step One - Do not stay in the basic schematic entry
Schematic design input for generating a logical connection is essential is concerned, it must be accurate, easy to use and integrated with the layout as a whole in order to ensure successful design.
Simply enter and transmits it to the schematic layout enough. In order to create high-quality design in line with expectations, the need to ensure the best use of elements, and can perform simulation analysis to ensure that the design will not go wrong at the time of delivery and manufacturing.
Step Two - Do not ignore the Library Manager Library
Management is an important part of the design process. To quickly select the best device and place it in the design, easy to create and easily manage the device it is very necessary.
PADS allows you to maintain all design tasks in a library, the library can be updated in real time, ease of use and to ensure that the design and development of accuracy. You can access all components via a single spreadsheet information without worrying about data redundancy, a plurality of tool library, or time-consuming overhead.
The third step - the effective management of design constraint rules
The key in today's high-speed design is very complex, if there is no effective means to manage the constraint rules, then the traces, topology and signal delay and other aspects of design, constraints, and management will become extremely difficult. To the first iteration to build a successful product, must be bound by the rules set early in the design process, in order to meet the requirements of the design goals. Good management constraint rule prevents you from using expensive or unable to purchase the components, circuit boards and ultimately ensure compliance with performance and manufacturing requirements.
Step 4 - Make sure that you have the required layout capability
In recent years, the complexity of the PCB layout significantly higher than before. In order to produce smaller, more portable electronic devices, the design had to increase the density. In addition, the operating frequency is increased, which requires designers to evaluate previously may have been overlooked in order to ensure the electrical characteristics of the design are available. To keep up with the pace of increasing complexity, the designer must have a broader ability to define advanced rule sets, create a unique shape and implement correct RF structures to improve the overall performance of the design.
Layout process, the intelligent layout tool helps create efficient placement and routing strategies. Precision arrangement can minimize irregularities design late, so you can more quickly complete the project in the case of small mistakes.
While the general use manual routing to achieve true design intent, but the interactive routing and automatic routing for effective with the use of the market helps meet deadlines, and improve design quality. Automatic routing can also help cope with difficult tasks, such as differential pair routing, network tuning, manufacturing optimization, and micro vias by layer technology. If the wiring is good advance planning strategy, using automatic routing efficiency will be greatly improved.
Another challenge is to maintain a modern PCB thousands of networks, which may create difficulties for the critical areas in the design of the wiring. Best way to avoid this problem is the network cable into groups in order to create an effective routing strategy. After you create a planning group, you can tag and filter network group, to highlight the critical need for network cabling.
