DFM guidelines include the Trace Carry Capacity Charts for Maximum Current Amps and the Conductor Thickness and Width for meeting Design for Manufacturing requirements. Several choices of common units are available. It can also be used for copper bars (e.g. tracks) of given width, thickness, length, and temperature. This online web calculator finds the resistance of copper PCB traces (a.k.a. This Printed Circuit Board Design section contains the latest researched information, various design calculators such as a Trace Width Calculator (calculates the trace width based on a curve fit to IPC-2221) and a PCB Via Calculator (calculates the resistance, voltage drop, and power loss). PCB Trace Resistance Calculator January 24, 2006. In addition, you will find information on non-browning soldermasks, an LED materials chart for thermal and dielectric characteristics and thermal property basics. We also provide the latest researched information, archived webinars, industry articles, design tools like thermal calculators, fabrication notes. LED Thermal Management Resource Center The LED PCB Resource Center contains materials for Light Emitting Diode Printed Circuit Boards.
Additionally, the Resource Center contains Fabrication Notes for both Laminate Choice Guidelines and Pb-free HASL Minimum Thickness Guidelines. With the exception of special cases such as very high frequency signaling and high power applications these rules can be applied to every PCB.
We have also archived our Lead Free webinars, research information and industry articles. When picking trace widths to route a PCB, there are a few rules and guidelines that will help inform the value of the trace width. RoHS Lead Free Resource Center The Pb-Free Resource Center contains information regarding RoHS compliance and requirements for specifying Lead Free printed circuit board materials, laminated and final finishes.
