Component and Pattern editors support a smart library structure and quick component creation using integrated templates. If you select option 'Use Pattern's Pad Properties' it means that this pad has default properties. Like a paste opening shrink percentage would be appropriate rather than a hard dimension. Default pad properties are used for all pads within a pattern except pads that have custom properties. That affect an 0201 on the same board?" - An 0805 aperture size of approximately. 004" aperture shrink is about right for an 0805, how will Board 3D model can be exported to mechanical CAD (STEP, VRML). The 3D module allows the designer to preview the board with installed components on any design stage, rotate and move it in real-time with hardware acceleration. On the pattern design area you can create and edit pattern objects (pads, shapes. Works as a part of the PCB Layout and Pattern Editor. Once weĭiscovered the cause of those issues, I started down the rabbit-hole of "if a. Component Editor draw schematic symbols and attach patterns. 004" - this led to some negative aperture issues that I inquired about in another post. There is an option to undersize the paste layerīy a given value, our default was. Circle, lines (headers, DIP), square (QFP), matrix (BGA), rectangle (RQFP), and zig-zag standard templates. Creation of pattern is basically selecting a template, entering a couple of vital parameters, drawing the silkscreen, and launching automatic pad renumbering. This has led us to some issues when creating our stencils. Custom templates can be created for non-standard patterns. We use many different size components on our boards, everythingįrom 0805 down to 0201. Our company has recently brought our PCB assembly in-house. Maybe we'll see some of the old cobwebs get dusted out after their fascination with Differential Pairs has subsided. As you have witnessed, it's better to start from scratch. (Perhaps it's one of those "invisible" gray elephants in the gray-walled development room?) I agree that it would be nice to be able to edit the spacing without having to select the entire pattern ( Ctrl+ A) and rotate ( Ctrl+ Alt+ R), flip the pads by exchanging the Width and Length values, renumber the pins that have magically received duplicate numbers and then redraw the silkscreen. KevinA wrote.My point is reuse, libraries are there for reuse but if altering a pad can not be done there is no reuse.The weird silkscreen distortion/movement problem while editing an existing pattern has been a DipTrace " feature" for as long as I have been using it, and I am not aware of any official responses to past complaints about this. ![]()
