Four steps to ensure the success of the PCB design

- Aug 12, 2016-

   To bring products fast and reliable push to the market and make use of the design tool to realize the automation of design process is very necessary, but how can we ensure that design to obtain success?? to greatly improve the design efficiency and product quality. We should pay attention to what the details? Design tools should obviously be intuitive and easy to use and powerful enough to overcome the complex design challenges, but what matters worthy of note? This paper lists to ensure the PCB design can take four steps.

   The first step - do not stay in the basic schematic input

The schematic input is very important for the logical connection of the generative design. It must be accurate, simple and easy to use, and can be integrated into the layout to ensure the design success.

   Simply enter the schematic and send it to the layout is not enough. In order to create a high quality design that meets the expectations, it is necessary to ensure the use of the best components, and the simulation analysis can be performed to ensure that the design will not be a problem in the delivery of manufacturing.

   The second step - do not ignore the library management

Management is an important part of the design process. In order to quickly select the best component and place it in the design, easy to create and easy to manage the device is very necessary.

   PADS allows you to maintain all design tasks in a library, and to update the library in real time, in order to facilitate the use and to ensure the accuracy of the design and development. You can access all of the components information through a single spreadsheet without worrying about data redundancy, multiple libraries, or time consuming tools.

   The third step: effective management of design constraints

Nowadays, the key high speed design is very complex. If there is no effective method to manage the constraint rules, the design, constraint and management of the line, topology and signal delay will be very difficult. In order to build a successful product in the first iteration, the constraint rules must be set at the early stage of the design process so as to reach the goal of the design. Good control rules can prevent you from using expensive or unable to purchase components, and ultimately ensure that the circuit board to meet the requirements of performance and manufacturing.

   The fourth step - to ensure that you have the required layout ability

In recent years, the complexity of PCB layout design is significantly higher than that of the previous. In order to make smaller, more portable electronic devices, the density of the design has to be improved. In addition, the operating frequency is increased, which requires designers to assess the electrical characteristics that may have previously been ignored to ensure that the design is available. In order to keep up with the increasing complexity of the pace, designers must have a wider range of capabilities in order to define a set of advanced rules, create a unique RF shape and implement the calibration structure to improve the overall performance of the design.

   In the process of layout, intelligent layout tools help to create efficient layout and routing strategies. Precise layout can reduce violations of the late design, allowing you to be able to complete the project more quickly in the case of fewer mistakes.

Although generally use manual wiring to achieve the design of the real intention, but the interactive routing and automatic wiring can help to meet the requirements of the market time effective collocation, and improve design quality. Automatic wiring can also help to cope with difficult tasks, such as differential wiring, network adjustment, manufacturing optimization, micro through hole and layer by layer technology, etc.. The efficiency of the use of automatic wiring is greatly improved if the routing strategy is planned in advance.

Another challenge is the modern PCB to maintain thousands of networks, which may bring difficulties in the design of the key areas of the wiring. The best way to avoid this problem is to divide the network into groups in order to create an effective routing strategy. When you create a planning group, you can mark and filter the network group to highlight the key network that requires wiring.
