Pre Cap Visual Inspection per Mil-Std-883 (TM 2017)

Pre Cap Visual Inspection per Mil-Std-883 (TM 2017)

Instructor: Thomas Green

Description: Hybrids/MCMs/RF Microwave Modules all require a visual inspection step just prior to encapsulation or hermetic seal. This is a critical process step that requires a high degree of operator skill and understanding of what to look for and reject as part of the inspection process. This course defines the inspection criteria based on traditional Mil Spec requirements in conjunction with industry accepted best commercial practices. Over 250 color photographs of actual production defects are reviewed and discussed in detail. The students are exposed to a variety of defects and how the defects relate to the materials and process flow. Students learn what to look for as part of Pre Cap visual inspection and how to interpret and apply the very latest MIL-STD-883 criteria.

The course is intended for quality assurance personnel, inspectors, QEs and Process engineers, component engineers and lead operators and others responsible for inspection of the hardware prior to the final package sealing process.

The following is an approximation of what will be covered in each online or “virtual” training session.
