摘要

Processing variables in the polyurethane foam encapsulation procedure on an electronic assembly timer occasionally yielded foam which was dimensionally unstable. This change in size was large enough that the affected timers would not meet gage require¬ments and had to be reworked. This instability was indicative of a marginal process. A thorough investigation of the problem determined that inadequate mixing of the two constituents of the foam was the cause. To eliminate the cause of the marginal process, requirements were defined which were used as guidelines in specifying the necessary equipment. This specification was then issued to suppliers for quotes. Once the quotes were received, the capabilities of the different foam processing systems were reviewed to assure conformity to the specification.
