Altium's PCB Layout Capabilities PCB Layout Documentation PCB Component Placement

Technical Documentation Object & Layer Transparency The Object Visibility region of the View Configuration panel can be used to set the transparency of each PCB object. Use the Transparency slide bar to set the percentage or enter the desired percentage directly in the percentage field. Altium Designer also provides support for setting the transparency of each object type individually and on a per-layer basis for each layer that can be used in…

Technical Documentation Laying Out Your PCB The Demands of Electronic Product Design Welcome to the world of board design in Altium's electronic design software. Inside every electronics product is a printed circuit board, or PCB. In the early days of printed circuit board design the demands on the PCB were simple, the board provided mechanical mounting for the components and connected the appropriate pins together - implementing the…

Technical Documentation High Speed Design Understanding the Challenge This article does not attempt to provide a complete discussion of high speed design, for that there are a number of highly experienced and scholarly designers and engineers that have written excellent reference papers and books on the subject. Refer to the References section for links to these authors, and the papers used during research for this article. The purpose…

Technical Documentation Designing a PCB with Embedded Components The traditional approach to circuit board design has been to place the components on the top and bottom surfaces of the board. This process is well supported by circuit board assembly houses, which typically use automated pick and place machines to position each component, ready to be soldered onto the surface. The ever-increasing demand for smaller and more integrated electronic products,…

Technical Documentation Board Panelization A printed circuit board is not fabricated as a single entity; typically a number of boards are fabricated on a panel. The panel can be defined by the fabricator, or alternatively, the board designer can create a panel in the PCB editor, using a feature referred to as an Embedded Board Array, also known as panelization. An Embedded Board Array is a primitive design object that you place into the…

Technical Documentation Board Insight System Board Insight is a configurable system of features that gives you complete control over viewing and working with your PCB design. A complex multi-layer board makes for a visually dense and often difficult to interpret design space. Altium Designer's Board Insight system makes it easier to view and understand the objects in your design. It consists of an integrated set of features developed to…

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 PCB Positional Annotation A key ingredient of good board design is component layout. In a large design, a component's position on the board may have no relationship to its designator. For example, R1 may end up on the opposite side of the board to R2. To make it easier to locate a component on the board, you can reassign the designators (re-annotate the board) positionally. To systematically assign designators of targeted…

Technical Documentation Testpoint Rule Types The design rules of the Testpoint category are described below. The Testpoint 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…
