| Parameter | Recommended Value | |-----------|-------------------| | Minimum trace width | 0.25 mm (10 mil) for signals; 0.5 mm for power | | Minimum clearance | 0.2 mm (8 mil) | | Pad size for THT | 1.6 mm diameter (hole 0.8 mm) | | SMD pad dimensions | According to component datasheet | | Copper pour (ground) | Recommended on top layer if bottom is crowded |
Let us walk through creating a macro specifically for a 60% keyboard top layer. We will assume a standard MX switch footprint (1U size) with a through-hole diode.
The biggest complaint about 60% is the lack of arrows. Solve this with a macro that turns the bottom-right modifiers into a navigation cluster.
When working on a 60 top (small board, lots of traces), layer confusion is your enemy. Sprint Layout uses a color-coded system: macros sprint layout 60 top
| Layer Name | Color (Default) | Purpose in 60% Keyboard | | :--- | :--- | :--- | | C1 (Top Copper) | Red | Signal traces, switch pads, component footprints. | | C2 (Bottom Copper) | Blue | Ground plane, USB routing, jumper wires. | | Silkscreen Top | Yellow | Key legends (A, S, D, F). | | Board Outline | White | The physical 60% shape (approx. 285mm x 95mm). |
| Error | Consequence | Solution | |-------|-------------|----------| | Macro placed on wrong layer | Copper appears on bottom side | Edit macro and reassign pads to top layer | | Missing silk outline | Component placement ambiguity | Add silk shape on top silk layer | | Incorrect pad numbering | Assembly/auto-routing issues | Verify pad sequence matches schematic |
This feature introduces a dedicated Macro Management system tailored for the Top Layer of PCB designs. It allows users to record, save, and parameterize common layout patterns (pads, traces, and silkscreen) to expedite the creation of custom components and repetitive geometries without relying on external libraries. Insert date/time:
Sprint-Layout 6.0 uses a specialized macro-library located on the right side of the interface to manage component footprints like ICs, resistors, and transistors. Managing Macros and Layers
Top Layer Visibility: Macros are placed on a workspace that supports copper and silkscreen layers for both the top and bottom sides. You can toggle these layers on or off at any time using the layer changer tool.
Installation Path: To add new or custom macros to your library, place them in the following directory on your computer:C:\Users\Public\Public Documents\Layout60\MAKROS. Window manager switch:
Placement: To use a macro, select it from the tree-view in the library and drag and drop it directly onto your layout. Key Macro Features
