Abstract: Size reduction of two new multianode microchannel array (MAMA) readout systems is described. The systems are based on two analog and one digital application specific integrated circuits (ASIC). The new readout systems reduce volume over previous discrete designs by 80% while improving electrical performance on virtually every significant parameter. Emphasis is made on the packaging used to achieve the volume reduction. Surface mount technology (SMT) is combined with modular construction for the analog portion of the readout. SMT reliability concerns and the board area impact of MIL SPEC SMT components are addressed. Package selection for the analog ASIC is discussed. Future systems will require even denser packaging and the volume reduction progression is shown. !2
