The information can be applied to almost any PC board package available. This article does not focus on the use of any one package, so This is in no way related to the Protel software. Confusingly, there is now another Windows-based package called AutoTrax EDA. Hobbyists use the excellent freeware DOS-based Protel AutoTrax program, which was, once upon a time, the high-end package of choice in Australia.
Professionals use the expensive high-end Windows-based packages such as Protel 99SE and DXP. Protel is the defacto industry standard package in Australia.

Those days are well and truly gone, with computer-based PCīoard design having replaced hand layout completely in professional electronics and largely in hobby electronics.Ĭomputer-based CAD programs allow the utmost flexibility inīoard design and editing over the traditional techniques. You can imagine how popular were the draftsmen (or probably draughtsmen in those days!) who made a mistake - and even more so, the designer who made a mistake in the first place and tried to blame it on the hapless draftsman! (which believe it or not was only around WWII), patterns were laboriously drawn using pen and ink. Bishop Graphics, Letraset and even Dalo pens will be names that evoke fond or perhaps not-so-fond memories.Įven before that, literally at the dawn of the PC board age Many hours were spent slouched over a fluorescent light box, cutting, placing, ripping up and routing tracks by hand. "If it looks good, it'll work good" is an old catch phrase.īack in the pre-computer CAD days, most PC boards were designedĪnd laid out by hand using black (or coloured) adhesive tapes and pads on clear drafting film. Many PC board designers like to think of PC board layouts as works of art, to be admired for their beauty and elegance.
There are many basic rules and good practices to follow but apart from that, PC board design is a highly creative and individual process. It is, however, quite difficult to "teach" PC board design.

It gives some advice and "rules of thumb" on how to design and lay out your PC boards in a professional manner. This article is presented to take some of the mystery out of PCīoard design. It must be remembered that PC board tracks have resistance, inductance and capacitance, just like your circuit does. In many designs (such as high-speed digital, low level analog and RF), the PC board layout can make or break the operation and electrical performance of the design. Proper PC board design is a crucial part of an electronic This is not surprising, considering that it often takes a great deal of knowledge and talent to position maybe hundreds of components and thousands of tracks into an intricate (some say artistic) design that meets a whole host of physical and electrical requirements. Many companies even have their own dedicated PC board designĭepartments.
Little about PC board design, and they leave it up to the "expert" specialist PC board designers. There are even very experienced circuit designers who know very But for others it can be a very daunting task. Now it's time to turn it into a nice Printed Circuit Board design.įor some designers, producing the PC board will be a naturalĪnd easy extension of the design process. You've designed your circuit and perhaps even built a working prototype.
