A Molded Carrier Ring (MCR) is a plastic component used in the packaging hierarchy of electronic devices. It serves as a protective ring that is molded to hold and safeguard certain components, such as plastic quad pack (PQFP) components, during the manufacturing process. The MCR plays a crucial role in ensuring the integrity and stability of the components throughout production. However, it is important to note that MCRs can sometimes have mold flash, which refers to the presence of plastic debris that remains on the ring after the manufacturing process. This debris can be a byproduct of the molding process and needs to be carefully managed to prevent any negative impact on the functionality of the components. Molded Carrier Rings are essential components in the packaging and protection of electronic devices, providing a secure and reliable housing for critical components.
