Keeping money in YOUR pocket Part 2/5 - Aspect Ratio

Reduce Aspect Ratio Using Pad Via Libraries/Templates in Altium Designer

  In PCB fabrication, the aspect ratio is the thickness of a PCB divided by the smallest diameter size of a drilled hole. It's importance relates to the plating process. Plating solutions must flow through the hole efficiently in order to achieve acceptable copper plating. Hole sizes that are small compared with the board thickness can result in unsatisfactory plating, and also elevate unit cost. To raise the design reuse and management capabilities for Pads and Vias in PCB designs to a new level, Altium Designer has introduced automated Pad and Via templates, Pad and Via template Libraries, and a number of associated Pad and Via management Panels. The concept of Pad and Via templates that can be collected in a Library is not unlike that of PCB footprint Libraries. The templates are composed of design elements with defined properties, and these can populate an associated library. In turn, this saved library can be reloaded and used to place instances of predefined Pads and Vias in any PCB design. However, note that there are a few unique aspects of Pad & Via templates and libraries, and the way they are managed. The advanced Pad and Via Template features in Altium Designer include:   See how the Pad Via Library/Template can help you keep money in your pocket [embed][/embed]   Learn more on Pad Via Library/Templates by visiting   Jamey Larocque, C.I.D Application Specialist CAD MicroSolutions Inc. 65 International Boulevard, Toronto ON, M9W 6L9 Canada | T: (416) 213-0533 ext 232
