The C&P20 placement head uses a vacuum-based holding circuit as part of its component handling process. That makes the 03005123 Hold Circuit Assembly a head-level service component, rather than a general machine circuit board or an individual nozzle part.
For SMT maintenance teams, its value lies in servicing the holding-circuit section of the C&P20 head. The part is listed in the SIPLACE X Series maintenance documentation as a replacement item when required, so it can be sourced as part of targeted head maintenance rather than automatically replacing the entire placement head.
We supply ASM SIPLACE spare parts and can check availability of the 03005123 assembly for your maintenance or inventory requirements.
