88 PCB007 MAGAZINE I FEBRUARY 2024 Printed circuit design and layout is a cre- ative process that has profound implications for electronic products. With the need for more parts on an assembly, or the trend to make things smaller to be portable or for faster speeds, the design process is a challenging one. e process is one of "balancing the density equation" (Figure 1) with considerations for Balancing the Density Equation certain boundary conditions like electrical and thermal performance. Unfortunately, many designers do not realize that there is a math- ematical process to the layout of a printed cir- cuit. e density equation has two parts: the component wiring demand (Wd) on the le, and the substrate wiring capacity (Wc) on the right.
