PCB design and manufacture of commercialization to follow these rules

This article will introduce the most effective design rules for electronic design engineers should keep in mind and practice in the use of design software for PCB layout design and commercial manufacturing ten. Engineers do not need to chronological order or the relative importance of the implementation of these rules, just follow the actual conditions can dramatically change the product design.
 Rule 1: Choose the correct mesh - and always capable of setting up matching element grid spacing. Although the multi-grid utility seems obvious, but if engineers can think more about some of the PCB layout design stage, will be able to avoid the problems encountered and to maximize the application circuit board when the interval. Since many devices are available in a variety of package size, engineers should be most conducive to their own designs. Further, the circuit board copper polygon critical, the circuit board carrying multigrid typically produce a copper-clad polygon polygon filling variation, although not based on a single network then the standard, but it can provide the required service life beyond the circuit board.
Rule two: Keep the shortest most direct path. This unusual sounds simple, but it should be at each stage, even if the means to change the circuit board layout to optimize wiring length should be kept in mind. This system is also particularly suitable for the performance is always limited by the impedance portion and parasitics analog and high speed digital circuits.
Rule three: as a power supply layer using the distribution management of the power line and ground. Power for most copper layer PCB design software is also faster simpler option. Large number of conductors carried by a common connection, can ensure maximum efficiency or pressure drop and having a minimum impedance of the current, while providing sufficient ground return path. If possible, the plurality of power supply lines can also run in the same region of the circuit board, to confirm whether a ground layer covering most of a certain layer PCB level, it is a good interaction between adjacent layers on the work line.
Rule 4: grouping together related elements with a desired test point. For example: The discrete components required for the operational amplifier OpAmp placed in the part close to the device from the bypass capacitor and the resistor can be co-located therewith, to help optimize the wiring length mentioned two rules, while also allowing testing and fault detection it easier.
Rule five: the desired repetition copy board another many times larger circuit board PCB imposition. Choose the most suitable size used by the manufacturer of the device helps reduce prototyping and manufacturing costs. First performed on the panel circuit board layout, the circuit board contact the manufacturer to obtain their preferred sizes of each panel, and then modify your design specifications, and try to be repeated several times in your design within these panel sizes.
Rule six: integration component values. As a designer, you can select some elements or high or low, but performance as discrete components. By integration, simplified bill of materials in a smaller standard value, and may reduce costs. If you have a range of PCB products based on the value of the device of choice, then the longer term perspective, but also more conducive to you to make the right inventory management decisions.
Rule Seven: as much as possible to perform design rule checking (DRC). Despite running DRC functions on the PCB software only takes a very short time, but in a more complex design environment, as long as you always check is performed during the design process can save a lot of time, which is a good habit worth keeping. Each routing decisions are critical, may at any time by performing the DRC prompt you that the most important wiring.
