The Effect of PCB Layout on ACS706 Thermal Performance
Eight different PC boards were fabricated to characterize the effect of PCB design on the operating junction temperature of the
Hall-effect IC inside of the ACS706. These PC boards are shown in the figure below.
2 oz. Cu on one side of board
2 oz. Cu on both sides of board
An ACS706 device was soldered on to each PCB for thermal testing. The results of the testing are shown in the following table.
