In Memoriam – Brian Butler
Brian joined the IPC D-21c High Speed/High Frequency Controlled Impedance Task Group in early 2000. He volunteered for numerous IPC task groups dedicated to high speed/high frequency design, serving as chair of the IPC D-24a Characteristic Impedance Test Methods Task Group and vice chair of the IPC D-24d High Frequency Signal Loss Task Group. In doing so, Brian led numerous efforts to develop and revise IPC-TM-650 Test Methods for usage by printed board fabricators in these technology areas.
His energy, enthusiasm and valuable contributions to the industry will be missed by many. On behalf of the electronics industry, IPC offers its condolences to Brian’s wife, Christine, their sons, Daniel and Ben, and Brian’s parents.
