Most fabricators can do 5 mil lines and 5 mil spacing, but 8 mil spacing is a typical minimum spacing used by board designers. I'll try and update this as a reference Real world typical figures are 10/10 (1.27mm) and 8/8 for basic boards. Printed Circuit board PWB layout and design guidelines. This plane is commonly formed by a metal case or ground area on a PCB. I went ahead and updated my references from IPC-D-275 to IPC-2221. This Javascript web calculator calculates the trace width for printed circuit boards based on a curve fit to IPC-2221 (formerly IPC-D-275). I'm doing lots of PCB layout at the moment for RF and digital projects and have been come up with these rules of thumb from various sources. Relevant material, summarized the PCB design process design SMT member of the self-examination and professional technology personnel review content and the engineering project, for product designers and craft reference. In time you'll begin to see several commonly used conversions like 100mil = 1.27mm. One of the key aspects that most designers forget is that when the product is in large volume production, PCBs are panelised (multiple PCBs in one large standard PCB size). I was asked to write a white paper for the APEX/IPC conference in Las Vegas, on the subject of basic thermal management of LEDs on MC-PCBs. The Poor Man's PCB Via Modeling Methodology. The method of mounting will impact the PCB design, specifically, the hole placement for the, as yet, undecided method of supporting and fastening the faces. In general 100mil is the basic reference point for all aspects of pcb design. So while the area is based on a non-linear formula, the thickness has a basic linear scaling effect. IPC standards see http://www.johnstowers.co.nz/blog/index.php/reference/altium-designer-tips/ for some grate tips. The ground plane acts as a counterpoise that forms the other 1/4-wave element, creating in essence a half-wave dipole. Abstract: based on the PCB design process, designers should follow the principles and methods of design, stage complete, designers must the self-examination and process engineering staff review of projects with the content are discussed.
