Quadcept : Various References
Reference: Pad Dimension
The following will explain the reference Pad Dimensions used by our company's Design Department.
These are references used by our company, so they may differ depending on the component type and board manufacturing method.
For taking pad (land) intervals, different dimensions from the references below may be used for creation.
* Principally, Solder Resist is created using the pad (land) dimensions +0.2 (+0.1 for one side), but it may be made smaller when the interval cannot be taken.
Reference Pad Size (SMD)
| Pitch | Lead Width | Electric (Top) Land Width |
