PCB Printed Circuit Board Design Guide. Lets begin with the basics for those new to PCBs. Printed circuit board PCB in general is any structure made of one or more layers of insulating material with electrical conductors designed to mount and connect electronic components. The insulator is typically made on the base of fiber reinforced resins, although it can also use ceramics, plastic, or some other dielectric materials. During manufacturing, the portions of conductors that are not needed are etched off, leaving desired tracks that connect the parts. Alternatively, the conductors can be added by an electroplating process. Currently, the main generic standard for PCB design, regardless of materials, is IPC 2. B. It provides rules for manufacturability and quality, such as requirements for material properties, criteria for surface plating, conductor thickness, component placement, dimensioning and tolerance rules, and more. This standard applies to all printed circuit board types including single sided, double sided and multilayer. For a specific technology, you may then choose an appropriate sectional standard from the IPC 2. For SMPS power conversion designs, additional parameters are recommended by IPC 9. B. To do your design you obviously need a software. Most large companies use Allegro by Cadence. The other choice is PADS by Mentor. There are also some free open source programs. PCB design includes the following main steps. Create footprints of all the components and make a schematic by using a schematic capture program Set design rules such as size of the conductors and spacing between nets Place and route all parts Pour ground planes connected to the ground nets Run connection check Generate files for the board fabrication usually it is Gerber files. When you enter design rules, the width and thickness of the conductors should be chosen based on maximum allowable temperature rise at the rated current per IPC 2. There is another criterion that is often overlooked. The trace should not melt during brief surge currents that can develop in the circuit.

You may use one of the following SI prefix after a value ppico, nnano, umicro, mmilli, kkilo, Mmega, Ggiga. This requires sufficient cross sectional area of copper as a function of overload amp seconds. The spacing between the PCB tracks is determined by peak working voltage, the coating, location of the circuit, and the product application. The minimum possible widths of the traces and of the spacing between them are both limited by the manufacturing capabilities of your fabricator. In any case, I would avoid using the width and spacing less than 4 mils. Typical guidelines for minimum values are 66 mils. Depending on the application and product end use, other standards may also apply. For example, for mains powered or battery powered information technology equipment, the creepage and clearance requirements of IECUL 6.

Once you set the design rules you can place the parts and do the routing. IPC and other standards do not tell you how to properly route the board. Good PCB layout techniques require an understanding of the effects of non zero trace impedance and the coupling of signals from one circuit to another through parasitic capacitances and radio transmission, as well as a basic understanding of circuit operation. Auto placement software may be used for most parts of control circuits, but power, ground and high didt circuits should be routed by hand. At the end, the design information has to be transferred into the form that can be sent to a fabricator. The set of the data that describes the board normally includes Gerber files as well as files in Excellon and other formats.
