Technical Documentation SMT Rule Types The design rules of the SMT category are described below. The SMT category of design rules. Done - 26.6, at Beta release: disable Beta and Altium employee for the conditional box above, enable Beta and Altium employee for the conditional box below. When PCB.Rules.RuleSets is out of Closed Beta, at the Public release: delete the conditional box and the content above, remove the box below, leave…

Technical Documentation Routing the PCB Parent page: More about PCB Design Working in harmony with the component placement, the routing is the other key factor in the success of your PCB design. Altium Designer includes a number of intuitive interactive routing features to help you efficiently and accurately route your board, from a simple double sided board all the way through to a high density, high speed, multi-layer board. It also…

Technical Documentation Automated Board Layout using the Situs Topological Autorouter An Introduction to Topological Autorouting Parent page: The Routing Routing the connections on a printed circuit board is a complex and time consuming activity. On large or dense boards, the process of routing can take a designer considerable time - time that is becoming increasingly rare as pro duct life-cycles shorten. Autorouters aid a designer in the routing process by automatically placing…

Technical Documentation Routing Rule Types Parent page: PCB Design Rule Types The design rules of the Routing category are described below. The Routing category of design rules. Width Default Rule: required i This rule defines the width of tracks placed on the copper (signal) layers. Constraints Constraints for the Width rule, which apply to all layers. Enter layer-specific values in the grid (hover the cursor over to show). Preferred…

Technical Documentation Preparing a PCB for Routing Is it Ready to Route? There is a saying that PCB design is 90% placement and 10% routing. While you could argue about the percentage of each, it is generally accepted that good component placement is the most important aspect to good board design. Keep in mind that you may need to tune the placement as you route too, perhaps running a test autoroute on a dense area first to see if it is route…

Technical Documentation Quick Routing Tools The Quick Routing command (accessed from the main menu and the Active Bar) offers lighter routing with less settings and capabilities, suitable for simpler designs. Its general behavior and shortcuts is the same as the standard Interactive Routing command. Capabilities include: A number of routing modes, such as: stop at first obstacle, walkaround, and push and shove. Powerful dragging…

Technical Documentation Fanout & Escape Routes Parent page: Routing the PCB Altium Designer includes excellent surface mount component fanout tools, which also support BGA escape routing. The escape routing engine will attempt to route each pad out to just beyond the edge of the device - making routing connections to them much easier. Fanout and escape routing is launched from the Route » Fanout sub-menu of the main menus or using the…

Technical Documentation Glossing & Retracing of Existing Routes Parent page: The Routing Routing a printed circuit board is a detailed, iterative process. Rarely are you able to simply route, or ActiveRoute, all of the nets in a single pass. More often you will be routing set of nets, and as you move on to the next set of nets you are continually adjusting and moving existing routes, perhaps manually dragging them, or perhaps pushing and shoving them as you…

Technical Documentation Modifying Existing Routes Parent page: Routing the PCB Routing a printed circuit board is a detailed, iterative process. Rarely are you able to simply route all of the nets in a single pass. More often, you will be routing a set of nets and as you move on to the next set of nets, you are continually adjusting and moving existing routes, perhaps manually dragging them, or perhaps pushing and shoving them as you…

Technical Documentation Strategies for Selecting the Routing Parent page: Routing the PCB One of the great challenges with interactive software tools is interfacing those tools to the designer's fingertips so they can easily and fluidly move between the various tasks, such as creating, reshaping and cleaning the routing. For this to happen, it must be easy to select the routes of interest. To select a routed net (or nets): Click to select an object…
