CALICE SiW ECAL - Development and test of the chip-on-board PCB solution

Résumé

The highly granular silicon-tungsten electromagnetic calorimeter (SiW ECAL) is the reference design of the ECAL for the International Large Detector (ILD) concept, one of the two detector concepts proposed for the future International Linear Collider (ILC). Prototypes for this type of detector are developed within the CALICE Collaboration. This contribution reports on the development of an ultra-thin PCB called Chip-on-Board (COB) that is equipped with wirebonded ASICs and pixelated silicon wafers. This set will form the basic unit of detection of the SiW ECAL. It will favour the design of an ultra compact calorimeter since these boards feature a thickness of 1.2 mm to be compared with the 3 mm of the default solution variant using ASICs in BGA packaging. We report also on the first results obtained with the COB boards on a beam test at DESY.
