Which materials fall into the "FR-4" category is defined in the NEMA LI 1-1998 standard. Typical physical and electrical properties of FR-4 are as follows. The abbreviations LW (lengthwise, warp yarn direction) and CW (crosswise, fill yarn direction) refer to the conventional perpendicular fiber orientations in the XY plane of the board (in-plane). In terms of Cartesian coordinates, lengthwise is along the x-axis, crosswise is along the y-axis, and the z-axis is referred to as the through-pla… riding two up on atvWebDec 1, 2024 · A typical operational goal is to keep the conductor temperature rise in your board within 10-20 °C. The goal in a high current design is then to size the trace width and copper weight so that temperature rise is kept within some limit for the required operating current.
