Tool Description
Trace max current is a requirement that designers specify to ensure that the trace can handle the required current capacity. This tool calculates the max trace current based upon the following design specifications:
- Trace Width
- Trace Thickness
- Max Desired Temperature Rise
This tool also calculates the following additional valuable information related to the trace:
- Resistance
- Votlage Drop
- Trace Power Dissipation
After a user specifies the trace width, trace thickness, and desired max temperature rise, the tool calculates the max current. This tool is based on charts in IPC-2221
