Fiber Reinforcement Induced Warpage on Injection Molded Thermoplastics

1 Abstract The warpage characterizations of injection molded plastic parts are not standardized and very challenging due to its complex process. This paper presents a novel examination method of the deformation of injection molded plastic parts especially for fiber reinforced materials. A special, but simple part was introduced for the description of the effect of different technological parame...

Analysis of Cavity Pressure and Warpage of Polyoxymethylene Thin Walled Injection Molded Parts: Experiments and Simulations

Process analysis and simulations on molding experiments of 3D thin shell parts have been conducted. Moldings were carried out with polyoxymethylene (POM). The moldings were performed with cavity pressure sensors in order to compare experimental process results with simulations. The warpage was characterized by measuring distances using a tactile coordinate measuring machine (CMM). Molding simul...

Investigation of Warpage Induced on Molded Strip of Qfn Package

Warpage is known to be one of the primary molding issues during assembly of QFN package. It affects the package sawing process, and cause reliability issues. The main cause of warpage of area array packages is the coefficient thermal expansion (CTE) mismatch between the moulding compound and other components inside the package. The objective of this study is to investigate the warpage induced o...
