What is MCR

MCR, in the context of the PCB industry, stands for Moulded Carrier Ring. It refers to a type of tape used in fine-pitch chip packages to support and protect the leads. The Moulded Carrier Ring is created by embedding the ends of the leads in a strip of plastic. This method of construction ensures that the leads remain straight and provides a sturdy and protective structure for the chip package.
