The Complete Set
|This book is available in two versions:
Paperback, from Amazon.com (click link) ($35.00 USD)
PDF**, directly from UltraCAD (see below.) ($20.00 USD)
|Brooks has been looking at these relationships since the mid '90s,
and entered into a multi-year collaboration with Johannes Adam in 2014.
And he has assembled 27-plus years of knowledge into these pages.
Detailed PCB trace current/temperature charts cover 7 trace thicknesses
and 11 trace widths: 1/4, 1/2, 1.0, 2.0, 3.0, 4.0, and 5.0 Oz trace
thicknesses and 15, 25, 50, 80, 100, 150, 200, 250, 300, 400, and 500
mil trace widths. The text summarizes the factors that influence trace
heating (i2R) and trace cooling (thermal conductivity through the
dielectric, convection, and radiation.)
Internal traces are cooler than external traces because the thermal conductivity through the dielectric is more efficient. The change between internal and external temperatures increases as the external temperature increases, and also as the trace depth increases. Guidelines are provided to help estimate an internal trace temperature based on what the external temperature is/would be and the relative depth of the trace.
The charts are based on the work Brooks and Adam did in their recent book, “PCB Trace and Via Temperatures: The Complete Analysis,” 2nd Edition, 2017 (available on Amazon.com) and on subsequent modeling using Dr. Adam’s simulation software Thermal Risk Management (TRM).
