First, a carrier QFN package, the map molding process and process-induced warpage issue is described. In Section 3, the material models for describing the behavior evolution during the curing process are presented. In Section 4, the experimental methods for ...
Leadframe designs for minimum molding-induced warpage
WebFlatness Measurement of Chassis. To measure warpage and flatness, you have to determine the difference in height attained by several sensor heads at different locations on the part. In this instance, you won’t experience any measurement errors that are typically caused by chattering because the sensor heads do not move. Webleadframe, tooling, equipment and magazine design development. At the LF design stage, the optimum design is chosen based on virtual model that showed lowest leadframe warpage at different process tempearture. With availability of this data, the downstream process such as molding, trim and form and new magazine design are also assess upfront. fairdale spaceship
