Abstract:
1. A spatially optimized pattern for surface mount pads on a ball grid array package, comprising: an array of surface mount pads arranged in rows and columns, and spaced less than or equal to 0.5 millimeters measured center-to-center, the array comprising T pads divided into N groups of pads, where T and N are positive integers; each group of pads consecutively numbered G each pad in each consecutively numbered group G a number of pads P each of consecutively numbered groups G wherein the spatially optimized pattern has a quality score equal to FP/T; and wherein the quality score is greater than or equal to 2.0; wherein a total area A of the surface mount pads is A=T*(π*(pad diameter/2)
