About the PCB layout
The connections on the PCB should be identical to the circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation between the circuit and the layout.
PCB layout can be performed manually (using CAD) or in combination with an Autorouter. The best results are usually still achieved using atleast some manual routing - simply because the design engineer has a far better judgement of how to arrange circuitry. Surprisingly, many autorouted boards are often completely illogical in their track routing - the program has optimised the connections, and sacrificed any small amount of order that may have been put in place by manual routing. Generally autorouted boards are slightly harder for a technician to repair or debug, for this reason. Historically, PCBs used to be laid out by drawing or using stick on paper shapes on mylar film, - that really was manual routing!
The CAD PCB layout consists of several layers, for illustration purposes the holes, outline and component identification layers can be combined into one diagram. When we produce PCBs for clients, we use actual size checkplots during the design process. A PCB will usually have mounting holes and may possibly have cutouts, by cutting an actual size checkplot and placing it in the enclosure, you can see how it will be positioned in relation to other parts. We can also place components up against the pad markings as a quick double check of sizing.
Why outsource your PCB layout?
Today outsourcing of PCB design became a vital tool for business management which gives competitive cost and technology advantages. As a design house you may need additional resources frequently. Without having to invest yourself we will extend the resources for you. Higher clock speeds, faster switching and increasingly challenging density issues require a greater engineering input at the interface level if yields and output are to be maximized on the test floor. We understand how to design high-density, high-speed PCBs that are manufacturable and testable, meeting time-to-market and unit cost requirements.
Our philosophy on this is simple: we work hard to make the outsourcing model work for you. Without outsourcing, you take on the challenge of adding and balancing many liabilities/costs. During peaks, you hire, train, manage and outfit your in-house team with expensive tools. During valleys, you may need to lay-off designers and continue to pay for idle licenses and overhead. By outsourcing with TopLayout, you save the tangible and intangible time and money required to sustain an extended full in-house design team, all the while getting fast, professional results from an outstanding team that acts as an extension of your engineering department.
