3.2.9. Text Elements
Typical footprints should have exactly two text elements: {{NAME}}
and {{VALUE}}
.
The name should normally be placed at top of the package body, slightly above the outline and aligned at bottom center. The value should be placed at the bottom center, slightly below the package body and aligned at the top center.
Always make sure that the text elements do not overlap with pads or with the placement layer. Otherwise the text might be unreadable on silkscreen. In addition, text elements should usually be placed outside the Package body to still see them on silkscreen of an assembled PCB.
Keep in mind that the bottom-aligned anchor is placed on the text baseline. This means that some letters like “g” or “y” might extend slightly below the anchor.
Figure 1. Typical footprint name properties
Property | Name text element | Value text element |
---|---|---|
Layer | Top Names | Top Values |
Text | {{NAME}} | {{VALUE}} |
Alignment | Bottom Center | Top Center |
Height | 1.0mm (or larger) | 1.0mm (or larger) |
Stroke Width | 0.2mm (or thicker) | 0.2mm (or thicker) |
Letter Spacing | Auto | Auto |
Line Spacing | Auto | Auto |
Mirror | No | No |
Auto-Rotate | Yes | Yes |
Special cases These rules should be fine for many Packages, but probably not for all of them. For special cases it’s allowed to have slightly different properties if they are more suitable. |
