  • PBGA singulated substrate for model melamine cleaning
    Patent number: 6834658
    Abstract: An apparatus is provided to clean melamine deposits from tools and components that are used to form molds around and to therewith encapsulate BGA devices. The cleaning apparatus uses a dummy BGA substrate as part of and during the cleaning procedure. This dummy BGA substrate replaces the conventionally used copper strips that shield areas of the molding tools during the cleaning cycle. The dummy copper strips require, during and as part of the melamine cleaning process, frequent cleaning, which adds considerably to the time and expense of the melamine cleaning process.
    Type: Grant
